报告摘要:

Tandem organic solar cells consisting of two subcells with complementary absorption in series, provide a feasible way to harvest a broader range of solar spectrum and effectively minimize the thermalization losses of energy photons. For a highly efficient tandem cell, it is important for the subcells to minimize the absorption overlap and generate high and balanced currents. Therefore, to develop highly efficient blend system with wide-bandgap (WBG) polymer as donor and fullerene derivative as acceptor in the front cell would be an effective strategy. However, it is a challenge to obtain high short current density (Jsc) for this blend system. Herein, we introduced high efficiency WBG polymer as the donor material in the front cell of the tandem device, and get PCE of over 15.5%.
