Ternary Polymer Solar Cells based on Two Acceptors and One Donor for Achieving 12.2% Efficiency

Wenchao Zhao et al. Adv Mater. 2017 Jan.

Abstract

Ternary polymer solar cells are fabricated based on one donor PBDB-T and two acceptors (a methyl-modified small-molecular acceptor (IT-M) and a bis-adduct of Bis[70]PCBM). A high power conversion efficiency of 12.2% can be achieved. The photovoltaic performance of the ternary polymer solar cells is not sensitive to the composition of the blend.

Keywords: bis[70]PCBM; polymer solar cells; power conversion efficiency; ternary blends.
