heterojunction solar panels

REC has developed a new series of residential heterojunction solar panels with efficiencies ranging from 20.6% to 22.2% and an operating temperature coefficient of -0.24% per degree Celsius.

Huasun has secured an order for 2 GW of solar panels from Power China, while Deye said it is seeking to raise CNY3.5 billion to expand its inverter production capacity.

University of New South Wales researchers have identified four failure modes caused by damp heat in heterojunction solar panels with a glass-back sheet configuration. The failures could result in power losses ranging from 5% to 50%.

Huasun’s new PV modules have an open-circuit voltage of 49.46 V, a short-circuit current of 17.57 A, and a fill factor of 83.29%. Germany’s TÜV SUD has confirmed the results.

The consortium says it intends to develop a simplified approach and best practices to produce 2T perovskite-silicon tandem solar products. The modules should have a bifacial design, glass-glass encapsulation, and a power output of over 300 W/m2.

China’s 35.com said it will invest CNY 1.5 billion ($218.4 million) in the production of solar modules based on heterojunction cells.

Enel CEO Francesco Starace says the company is talking to an unspecified international investor about the sale of a 50% stake in its new 3 GW heterojunction solar module factory in Catania, which is scheduled to start operations in September.

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.

Recom’s newest solar panels feature efficiencies of up to 21.68% and a temperature coefficient of -0.24% per degree Celsius. The company is offering a 30-year power output guarantee for 91.25% of the initial yield.

Enel Green Power’s new solar panel has average efficiencies ranging from 22.6% to 22.9% and a temperature coefficient of -0.24% per degree Celsius. It is based on an n-type solar cell with G12 format and a power conversion efficiency of 24.6%.
