Solution-processed tandem organic solar cells

摘要

Organic solar cells(OSCs)show great potential in non-grid energy supply due to its unique properties including light-weight,flexibility,semi-transparency,design flexibility,low cost and so on.Thanks to researchers'tremendous efforts in materials development and device engineering,the power con-version efficiency(PCE)for single-junction OSCs(SJ-OSCs)has exceeded 18%[1,2].
