heterojunction solar modules

Beijian Energy says it will build a new factory to make heterojunction (HJT) solar cells and panels. The facility in Liaoning province will produce 4 GW of cells and 3 GW of PV modules.

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.

Enel has obtained €560 million ($610.2 million) for a solar module factory it is building in Catania, Sicily.

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%.

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.

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.

Indian manufacturer Goldi Solar has unveiled a 710 Wp bifacial solar module based on heterojunction (HJT) technology. The module is built with 132 half-cells and has a conversion efficiency of up to 22.85%.

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%.

A Dutch research group has developed a passivation technique for heterojunction solar cells based on a hydrogenated amorphous silicon layer. Their cell achieved an in-house-certified power conversion efficiency of 24.18%, an open-circuit voltage of 726.0 mV, a short-circuit current of 39.97 mA/cm2, and a fill factor of 83.3%.

The largest product of the series is a solar module with an efficiency of up to 22.5% and a power output of up to 700 W. For all the panels of the series, the temperature coefficient is -0.26% per degree Celsius and the manufacturer offers a 12-year product guarantee and a 30-year power output guarantee.
