文摘
The large energy loss (>0.6 eV) in polymer solar cells (PSCs) is limiting the improvement of photovoltage. In article number 1600148, Xiaofeng Xu, Wei Ma, Ergang Wang, and co-workers report that a low band gap (1.49 eV) polymer attains a high photovoltage of 1.0 V with efficiency of 6.7% in PSCs. It represents an impressively low energy loss of 0.49 eV, which challenges the current paradigm and reveals the potential to further enhance the performance of PSCs.
