Here comes the sun: Three highly efficient organic sensitizers with sterically hindered fluorenyl units and planar indenothiophene derivatives were designed and synthesized (see figure). Devices based on one of these compounds, JK‐303, gave overall conversion efficiencies of 8.69, 9.04, 7.27, and 5.82 % using I−/I3−, CoII/CoIII, polymer gel, and solid‐state electrolytes, respectively. These efficiencies
太阳来了:设计并合成了三种具有位阻芴基单元和平面茚并噻吩衍生物的高效有机敏化剂(见图)。基于这些化合物中的一种设备,JK-303,得到整体的转换效率的8.69,9.04,7.27,和5.82%使用I - / I 3 - ,钴II /钴III,聚合物凝胶,和固态电解质,分别。这些效率是基于有机敏化剂的DSSC报告的最高效率。
