We have designed two new BODIPY derivatives, denoted as 6a and 6b, substituted with truxene moiety and triphenylamine (TPA) unit groups and have investigated their optical and electrochemical properties. Dyes 6a and 6b were employed as donor along with PC₇₁BM or Y6 as acceptor for the fabrication of binary and ternary organic solar cells. After optimization of the binary and ternary active layers, we have achieved over all power conversion efficiency (PCE) of 11.37 % and 13.32% for 6a:PC₇₁BM:Y6 and 6b:PC₇₁BM:Y6 ternary organic solar cells, respectively, which are higher than the binary organic solar cells based on PC₇₁BM or Y6 acceptor. The higher power conversion efficiency for ternary OSC is possibly attributed to the better exciton generation rate, exciton dissociation and charge collection.

我们设计了两种新的 BODIPY 衍生物，表示为6a和6b，它们被三苯胺部分和三苯胺 (TPA) 单元基团取代，并研究了它们的光学和电化学性质。染料6a和6b与PC ₇₁ BM或Y6作为受体一起用作供体，用于制造二元和三元有机太阳能电池。在对二元和三元有源层进行优化后，对于6a : PC ₇₁ BM : Y6和6b : PC，我们实现了 11.37% 和 13.32% 的总功率转换效率 (PCE)₇₁ BM：分别是Y6三元有机太阳能电池，高于基于PC ₇₁ BM或Y6受体的二元有机太阳能电池。三元 OSC 更高的功率转换效率可能归因于更好的激子产生率、激子解离和电荷收集。
