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.
Recom launches bifacial heterojunction solar panel with 395 W output
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 unveils 680 W n-type heterojunction solar panel for utility-scale applications
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%.
Jinergy unveils all-black solar module series for rooftop PV
The all-black series includes a monofacial PERC module with an efficiency of up to 20.86% and an n-type heterojunction product with an efficiency of 21.68%. Both products feature all-black integrated design, with black backsheet, black busbar, black frame and black encapsulant material.
Enel, European Commission sign grant agreement for 3 GW Italian module factory
Enel plans to invest around €600 million in the expansion of its module manufacturing facility in southern Italy. The European Commission will contribute around €118 million to the total sum.
Enel mulls building heterojunction solar module factory in the US
In a recent media brief, new Enel Green Power CEO Salvatore Bernabei said the company’s heterojunction solar module factory in southern Italy will be scaled up from 200MW to 3GW by mid-2024. He also revealed that another factory may be built abroad, with the United States being a possible location.
Longi improves efficiency of its heterojunction cell from 25.82 to 26.30% in just one week
The result was confirmed, once again, by Germany’s Institute for Solar Energy Research Hamelin (ISFH).
TCO-free heterojunction silicon solar cell with 22% efficiency
The cell was built with a phosphorus-doped n-type Czochralski (Cz) silicon wafer with a resistivity of 1.09Ωcm and a thickness of 170mm. Ti/Au/Ag metal stacks were used for the contact with the hydrogenated amorphous silicon (a-Si:H) layers.
Meyer Burger unveils 400 W heterojunction solar module
The solar module will be available in three versions – white, black, and glass-glass. The products have an output of up to 400 W, but when the bifacial effect is optimally used, the output of the glass-glass module can reach up to 430 W. Both the white and black modules weigh less than 20 kg
Meyer Burger buys wafers from different manufacturers
Before the official start of production, the Swiss photovoltaic manufacturer signed contracts with several suppliers that only use polysilicon produced by Wacker Chemie. Meyer Burger plans to start producing its solar modules and cells in Germany in the second quarter.
