Researchers at Germany's Fraunhofer ISE have developed a silicon heterojunction (SHJ) solar cell utilizing intense pulsed light-processed screen-printed metal contacts, and claim to have achieved a ...

Since graphene has a low absorption coefficient in the absorption band, researchers generally use graphene as a carrier collection layer, and look for another strong light-absorbing material as the ...

Korean researchers revealed that efficiency losses in heterojunction solar cells arise from two coexisting defect types – dangling bonds and weak silicon-silicon bonds. Their findings explain how ...
