A new UNSW study shows that laser-enhanced contact optimization (LECO) can boost industrial TOPCon solar cell efficiency by improving contact properties and reducing recombination losses. By combining ...
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 ...
The TOPCon solar cells with fabricated with screen-printed, fire-through copper rear contacts and silver front contacts, using laser-enhanced contact optimization (LECO) to significantly reduce ...
