Fullerene Free Polymer Solar Cells with over 11% Efficiency and Excellent Thermal Stability.
A nonfullerene based polymer solar cell (PSC) that significantly outperforms fullerene based PSCs with respect to the power conversion efficiency is demonstrated for the first time. An efficiency of >11% which is among the top values in the PSC field, and excellent thermal stability is obtained using PBDB T and ITIC as donor and acceptor, respectively.
