Researchers in China have investigated the impact of phosphorus diffusion gettering on industrial silicon heterojunction solar cell and have found that, with an optimized gas flow, higher efficiencies ...

A research team led by Switzerland's EPFL has sought to simplify TOPCon solar cell production by combining the two required high-temperature steps – front-side emitter formation and rear passivating ...

According to the report’s authors, LECO is now used in the production of around one-quarter of TOPCon cells. Image: Trina Solar. A new study has found that the laser-enhanced contact optimisation ...

Perovskite solar cells also contain a small amount of lead that is necessary for high efficiency, but this also places great demands on a functioning recycling process. In addition, there are also ...
