设计、合成了四种新型吲哚并[3,2-b]咔唑基多供体π受体型有机染料QX01-04，并将其应用于染料敏化太阳能电池。这些染料由作为主要供体基团的吲哚并[3,2-b]咔唑核心和作为次要供体的乙苯、N,N-二乙基苯胺、乙氧基苯和辛氧基苯等几个基团组成。光物理、电化学和理论研究表明这四种染料都可以作为光敏剂。当引入N,N-二乙基苯胺作为第二供体时，QX02表现出更宽的吸收区域和显着提高的IPCE值，从而保证了良好的光捕获能力和15.2 mA cm(-2)的高J(SC)。最终，基于QX02的电池在100 mW cm(-2)照射下实现了8.09%的高效率，非常接近基于商业N719的电池（8.26%）。 (C) 2016 Elsevier B.V. 保留所有权利。
Four novel indolo[3,2-b]carbazole-based multi-donor-pi-acceptor type organic dyes QX01-04 have been designed, synthesized, and applied for dye-sensitized solar cells. These dyes consist of an indolo [3,2-b]carbazole core acting as the main donor group, a couple of groups such as ethylbenzene, N,N-diethylaniline, ethyloxylbenzene, and octyloxylbenzene acting as the secondary donors. The photo physical, electrochemical, and theoretical studies indicate that the four dyes are all capable as the photosensitizers. When introducing N,N-diethylaniline as the secondary donor, QX02 exhibits a broader absorption region and significantly improved IPCE values, which ensured a good light-harvesting ability and a high.) J(SC) of 15.2 mA cm(-2). Finally, QX02-based cell achieved a high efficiency of 8.09% which is very close to that of the commercial N719-based cell (8.26%) under 100 mW cm(-2) irradiation.
