Semi-transparent organic solar cells based on large bandgap star-shaped small molecules as mixed donors with PM6

Abstract

Two new star-shaped organic materials have been applied as ternary components in organic solar cells to give greater light transparency with only a small sacrifice in power conversion efficiencies.

Regioisomeric thieno[3,4-d]thiazole-based A-Q-D-Q-A-type NIR acceptors for efficient non-fullerene organic solar cells

“…1 Moreover, OSCs attract considerable research attention for their cost-effective fabrication, 2 large area printing, exibility, light weight, and semitransparency. 3 Typical bulkheterojunction (BHJ) OSCs comprise two mixed components of different energy levels and bandgaps, i.e., a p-type donor and n-type acceptor. The energetic difference between donors and acceptors induces a potential which results in charge dissociation of excitons at the donor-acceptor (D-A) interface, generated under solar irradiation.…”
