Dynamic photovoltaic blinds for glaze-façade buildings
Scientists from China have built photovoltaic blinds that can reportedly regulate thermal load, daylight penetration, and energy generation in high-rise buildings with glazed facades. Their creators claim the blinds offer superior architectural aesthetics and notable energy-saving potential.
Tandem solar cell based on cadmium telluride, iron disilicide promises 43.9% efficiency
Researchers in Bangladesh have designed a dual-junction tandem solar cell with a bottom device based on iron disilicide (FeSi2), an emerging absorber material know for its high thermal stability and good optoelectronic properties. Their simulation showed the advantage of combining the larger bandgap of the top cadmium telluride cell and the smaller bandgap of the bottom FeSi2 cell.
Austrian startup offers standardized system for solar bike roads
Austrian startup Mo Energy Systems has developed a standardized system for solar bike roads, featuring 12-meter-long structures with a variable width ranging from 2 meters to 4.5 meters. It includes anchoring, without the need for concrete or excavation work.

Jolywood has suspended plans to build 100,000 metric tons (MT) of polysilicon capacity at a facility in Gujiao, China’s Shanxi province.
Energy communities more profitable than individual self-consumption in Italy, Portugal
Researchers behind a techno-economic analysis of energy communities in Italy and Portugal say that collective self-consumption is a more lucrative solution than individual installations.
Indian scientists design 26.24%-efficient triple-junction all perovskite solar cell
The researchers simulated an all perovskite solar cell offering the advantage of effectively harnessing sunlight across a wide range of wavelengths. The device has the potential to achieve an open-circuit voltage of 3.76 V, a short-circuit density of 10.70 mA/cm², and a fill factor of 69.00%.
First attempt to build antimony photovoltaic modules
An Italian research team claims a first for solar modules based on air stable lead-free and tin-free antimony-based light absorber, a perovskite-inspired material. The mini modules have a 1.2% power conversion efficiency over a 2.52 cm2 active area.
Stacking algorithm for PV module fault diagnosis
Researchers in Norway have created a PV module fault diagnosis technique based on a stacking algorithm. It utilizes augmented digital images of PV modules collected by unmanned aerial vehicles and is able to detect snail trails, delamination, glass breakages, discoloration, and burn marks.
Construction starts on polysilicon production facility in Oman
Construction has begun on a $1.35 billion polysilicon production facility in Oman, billed as the first project of its kind in the Middle East. It is scheduled to start operations next year, producing 100,000 metric tons of metallurgical silicon per year.
Longi introduces HPBC photovoltaic modules with 22.8% efficiency
The Chinese panel manufacturer said its new products have a temperature coefficient of -0.28%/C and a power output ranging from 565 W to 590 W. They rely on the company’s proprietary hybrid passivated back contact (HPBC) cell technology.
