JA Solar said that the smallest solar panel in its new n-type product line has a power output of 435 W and a power conversion efficiency of 22.3%. The largest module in the series has an efficiency rating of 22.4% and 625 W of nominal power. Their temperature coefficient is -0.30% per degree Celsius.
In other news, Shinshu University researchers developed a graphene-wrapped molecular-sieving membrane that is reportedly 100 times more efficient than that of conventional polymer separation membranes. Topsoe aalso nnounced the construction of the “world’s largest electrolyzer production facility,” and Toho Gas said it would produce blue hydrogen in Japan for local consumption.
The new solar module can be purchased with different levels of transparency, depending on the project, with light transmittance ranging between 30% and 40%. It has a power output of 245 W to 300 W and a temperature coefficient of -0.30% per C.
Cost efficiency while maximizing power output is the name of the game in solar project development and asset management. And the automation of the provision of utility scale solar operations and maintenance (O&M) is fast becoming one of the most compelling opportunities.

German scientists have conducted a series of experiments on gallium-doped silicon solar cells to understand the causes of degradation in PV cells and modules treated with gallium rather than boron. They confirmed that the performance losses are caused by a bulk defect in the material, and found that the right combination of light and temperature can “heal” earlier damage and even lead to small improvements in overall cell efficiency.
Energy management startup Ez4EV has introduced an electric-vehicle charging solution with integrated battery storage. The complete unit-in-a-box can be charged using electricity produced from solar, compressed biogas, and compressed natural gas.
Researchers in China have fabricated a heterojunction solar cell with a 244.63 cm2 Czochralski n-c-Si wafer. They used light soaking to improve the dark conductance of the hydrogenated amorphous silicon films.
Researchers in Singapore have developed a new technique in which polycrystalline silicon is pulverized into powder and pelletized into ingots. The process relies on spark plasma sintering to dope the silicon with germanium and phosphorus.
