Abstract

Solution-processed hybrid solar cells employing a low band-gap polymer and PbSx Se1-x alloy nanocrystals, achieving a record high PCE of 5.50% and an optimal FF of 67% are presented. The remarkable device efficiency can be attributed to the high-performance active materials, the optimal polymer/NCs ratio and, more importantly, the vertical donor/(donor:acceptor)/acceptor structure which benefits charge dissociation and transport.

摘要

采用低带隙聚合物和 PbSx Se1-x 合金纳米晶的溶液处理混合太阳能电池，实现了创纪录的高 PCE（光电转换效率）5.50%和最佳 FF（填充因子）67%。显著的器件效率可归因于高性能的活性材料、最佳的聚合物/NCs 比例，更重要的是，垂直施主/（施主：受体）/受体结构有利于电荷的解离和传输。
