ABSTRACT

ABSTRACT

Fullerene-free organic solar cells show over 11% power conversion efficiency, processed by low toxic solvents. The applied donor and acceptor in the bulk heterojunction exhibit almost the same highest occupied molecular orbital level, yet exhibit very efficient charge creation.

Palavras-chave

aligned HOMO levels; efficient charge creation; efficient charge transport; green solvents; non-fullerene organic solar cells
