南开大学 陈永胜 有机小分子太阳能电池 7.4%
注意:在苏州GOPV太阳能会议上,陈永胜报告PPT上,类似结构达到8.2%效率 光伏中心验证效率为7.6%,相关文献应该很快会出来。为目前溶液加工报告最高效率
ABSTRACT: Small molecules, namely DCAO3TBDT and DR3TBDT, with 2.ethylhexoxy substituted BDT as the
central building block, octyl cyanoacetate and 3.ethylrhodanine as different terminal units with the same linkage of
dioctyltertthiophene, have been designed and synthesized. The photovoltaic properties of these two molecules as donors
and fullerene derivatives as the acceptors in bulk heterojunction solar cells are studied. Among them, DR3TBDT shows
excellent photovoltaic performance and power conversion efficiency as high as 7.38% (certified 7.10%) under AM 1.5G
irradiation (100 mWcm.2) has been achieved using the simple solution spin.coating fabrication process, which is the
highest efficiency reported to date for any small molecule based solar cells. The results demonstrate that structure fine
turning could cause significant performance difference and with that, the performance of solution processed small
molecule solar cells can indeed be comparable with or even surpass their polymer counterparts. |
