#Monofacial or #Bifacial? This is another question！ In the rapidly evolving photovoltaic (#PV) industry, both monofacial and bifacial modules hold significant market positions. Most solar modules were monofacial before 2018, as the back side of solar cell used to be covered by aluminum for backside field passivation. Monofacial modules generate electricity solely through front-side sunlight absorption. The backside is encapsulated with opaque materials to protect internal cells from environmental factors like moisture and dust, ensuring stability and longevity. This changed around 2018 with PERC cell design, as the backside of solar cell can be exposed for additional power generation. Canadian Solar was one of the first to introduce bifacial modules in 2018. We introduced bifacial modules based on #Topcon and #heterojunction (#HJT) #solar cells subsequently. Bifacial modules are encapsulated by glass or transparent sheet on the back so that they capture reflected light (e.g., from sand, buildings) and diffuse light under cloudy/low-irradiance conditions, boosting total energy yield. For example, in desert power plants with sandy ground (reflectance ~20–40%), bifacial modules achieve 10–30% higher output due to rear-side reflected light. Similarly, in distributed systems surrounded by buildings, rear-side gains further enhance performance. Are there standards for measurement of the backside power generation? The answer is Yes. IEC 61215 IEC61730 were officially modified in 2021 and 2023, respectively, to include “Bifacial Nameplate Irradiance” or #BNPI in addition to the Standard Test Condition (#STC) used for frontside power rating.  • STC Power: Measured under 25°C, 1000W/m² front-side irradiance, and AM 1.5. This metric provides a universal benchmark for comparing module performance under idealized conditions. • BNPI Power: Combines front-side irradiance (1000W/m²) and rear-side irradiance (135W/m²), reflecting dual-sided energy generation in real-world applications. For example, Canadian Solar 182Pro 620W bifacial module are labelled as: • 620W STC power (23.0% efficiency). • 687W BNPI power (25.4% efficiency), calculated using the same dimensions (2382 x 1134 mm). BNPI metrics more accurately represent the total energy yield of bifacial modules. BNPI power easily surpasses what monofacial technologies can achieve. In my next post, I will share our field testing results, comparing (1) bifacial with monofacial modules, and (2) high bifaciality modules such as Topcon and HJT with low bifaciality modules such as backside contacts (xBC). #SolarTechnology #ModulePerformance #SolarTesting

A team of scientists in Germany has created an ultra-thin type of solar panel that has the potential to revolutionize solar energy collection and usage. Developed at Martin Luther University Halle-Wittenberg, these panels are made from a unique layered combination of crystals—barium titanate, strontium titanate, and calcium titanate—stacked to a thickness of just 200 nanometers, which is roughly 400 times thinner than a human hair. Despite using significantly less material, these panels can produce up to 1,000 times more electric current than conventional silicon-based solar cells. The key innovation lies in the crystals’ natural ability to generate electricity when exposed to light, eliminating the need for the complex architectures found in current solar technologies. In addition to boosting efficiency, this breakthrough could reduce material waste and lower manufacturing costs, making solar power more affordable and easier to produce. This advancement contributes to the expanding range of solar energy innovations focused on making clean energy more accessible and sustainable for the future. #solarpower #solarpanels #renewableenergy

Germany has introduced transparent solar panels that let sunlight nourish crops while simultaneously generating electricity. Designed for agricultural greenhouses, these panels filter out only the light frequencies that plants don’t use, converting them into energy. Each panel can produce up to 165 watts per square meter, enough to power irrigation systems, sensors, and lighting directly from the roof. Farmers can now generate clean energy and food on the same land, doubling efficiency without harming yields. This breakthrough could transform farming, making it both energy-independent and sustainable. Experts call it a model for agrivoltaics, where agriculture and solar power coexist harmoniously. In Germany’s greenhouses, sunlight is no longer divided — it’s shared between food and energy. #SolarInnovation #GreenEnergy #Agrivoltaics

Stanford University researchers have achieved a significant breakthrough in renewable energy: solar panels that generate electricity at night by capturing the infrared radiation naturally emitted by the Earth. Unlike conventional panels that rely on sunlight, these systems exploit the temperature difference between the Earth and the cold night sky, converting thermal energy into electricity using thermophotovoltaic cells. The design features a bottom layer that absorbs Earth’s heat and a top layer that emits infrared light to space, which photovoltaic cells then capture. Early tests show that the panels can produce up to 25% of daytime solar output even at night, providing a continuous energy supply without the need for batteries or fuel. This technology addresses one of solar energy’s biggest challenges: intermittency. Continuous power generation could stabilize grids, reduce dependence on fossil fuel backups, and accelerate the adoption of renewables worldwide. Researchers envision rooftops, solar farms, and desert installations leveraging this passive, 24/7 energy source. The implications are enormous: with the ability to harvest energy day and night, communities can rely on cleaner, more reliable electricity while reducing carbon emissions. Stanford’s innovation marks a new era in sustainable energy engineering, merging physics, materials science, and environmental stewardship. #SolarInnovation #StanfordResearch #RenewableEnergy #CleanTech #SustainableFuture #NextGenSolar

BREAKING NEWS: A company in Texas has introduced a new vertical “solar tower” design that could dramatically improve how solar power is collected. Instead of spreading panels flat across the ground, these towers stack panels in a three-dimensional formation, allowing them to capture sunlight from multiple angles throughout the day. The panels also rotate to follow the sun’s movement, collecting low-angle light in the morning and evening that standard flat panels often miss. As a result, these towers can generate up to fifty percent more electricity while using only about one-third of the land area compared with conventional solar farms. Tests show that the towers achieve a capacity factor of roughly thirty-two percent, significantly higher than the average twenty-two percent seen in traditional installations. They also smooth out power generation by producing steadier output across the entire day rather than peaking at midday. The structures are built to withstand extreme wind speeds of up to one hundred seventy miles per hour, making them durable and practical for harsh environments. Because of their compact footprint, these vertical systems could be especially valuable in areas where land is limited or costly. Potential uses include powering airports, data centers, and electric vehicle charging stations. Early pilot projects suggest that these 3D solar towers could help maximize renewable energy output in urban and industrial settings, offering a promising solution for efficient, space-saving solar power generation.

Echo… Wow! South Korea’s scientists just built a transparent solar panel that looks like glass — but generates electricity from sunlight. At the Korea Institute of Energy Research, a team unveiled photovoltaic panels that are not only clear but also efficient enough to power homes, offices, and even cars without blocking natural light. Unlike traditional panels that are dark and opaque, these transparent versions can be used as windows, skylights, or even smartphone screens. The breakthrough comes from using organic photovoltaic materials layered in nanoscale films. These films selectively absorb invisible parts of the solar spectrum — ultraviolet and infrared — while letting visible light pass through. The result is a panel that appears just like ordinary glass, but silently generates clean energy in the background. This innovation could revolutionize urban design. Imagine skyscrapers where every window is a hidden solar generator, or buses and trains with energy-producing glass. Even household devices could carry self-charging transparent screens, reducing the need for frequent plugging in. One of the challenges in the past has been balancing efficiency with clarity. Many earlier prototypes sacrificed too much energy output for transparency. But the Korean design achieves over 12% efficiency while maintaining up to 80% transparency — a record for the field. The panels are also lightweight, flexible, and easier to install than bulky rooftop systems. If mass-produced, transparent solar panels could transform cities into invisible power plants. Energy-hungry buildings would become energy producers, shrinking reliance on fossil fuels and dramatically reducing carbon footprints. Researchers estimate that outfitting just half of a city’s glass surfaces with this technology could meet most of its electricity demand.— in New York, NY.

Switzerland made an invisible solar panel that turns windows into clean energy In a sunlit energy lab near Zurich, Swiss researchers have developed transparent solar cells that look like ordinary glass — but quietly generate electricity all day long. These invisible solar panels could turn entire buildings into power plants without changing their appearance. Unlike traditional solar panels that rely on opaque, black photovoltaic layers, these use organic photovoltaics (OPVs) tuned to absorb infrared and ultraviolet light — the parts of the spectrum humans can’t see. That means the visible portion remains clear, making the cells appear like standard window glass. When laminated between double-glass panes, the result is stunning: a building that looks like pure glass but silently powers itself using invisible wavelengths. These OPV layers are only nanometers thick, flexible, and extremely light — allowing for use in skyscrapers, cars, or even smartphone screens. In lab tests, the panels achieved 14% conversion efficiency — lower than traditional silicon, but far more versatile. Even better, they work in diffused light, cloudy weather, and from both sides of the window. Unlike older tech, they don’t block the view or need exact angles to function. Swiss architects are already integrating these into smart building designs, where the entire glass façade becomes a living solar skin. Combined with battery walls, such buildings could go off-grid entirely — producing more energy than they use. This could turn every city skyline into a solar farm — with no one even noticing
