China mulling restrictions on polysilicon, wafer production tech exports
The Chinese government is considering the introduction of export restrictions on solar wafers, black silicon, and silicon casting equipment. It has launched a public consultation process on the proposed measures.
Novel snow-removal tech uses electricity from uncovered PV panels
JA Solar has worked with Chinese scientists to test a new electrical heating system for solar panels that uses the heat from uncovered panels to remove snow. The system starts by using grid electricity, but then relies on the thermal effect of resistance to uniformly heat the whole PN junction area of the snow-covered panels.
TÜV Rheinland opens solar module testing lab in China
Germany’s TÜV Rheinland said it will invest €22 million in the 5,000 m2 facility for testing photovoltaic modules as part of a massive lab.
Spray passivation to reduce losses in TOPCon, HJT cell-to-module process
Chinese researchers have developed a new passivation technique for shingled solar panels based on tunnel oxide passivated contacts (TOPCon) or heterojunction (HJT) tech. It reduces recombination losses in the cell-to-module process and reportedly increases open-circuit voltage, fill factor, and efficiency.
JA Solar to build new vertically integrated solar factory in China
JA Solar says it will build a new manufacturing facility in Inner Mongolia, China. The plant will produce everything from polysilicon to solar panels.
Renac unveils high-voltage hybrid inverters for residential applications
