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 ...
Imec has successfully integrated silicon heterojunction PV cells into curved surfaces, resulting in a 6% efficiency increase compared to passivated emitter and rear contact (PERC) half cells.
Although the efficiency of their graphene-on-silicon solar cell is currently quite low, the researchers envisage that it can be improved by optimizing the conductivity and transparency of the ...
