4',6-Diamidino-2-phenylindole (DAPI) and Hoechst 33342 (H33342) were used as novel energy relay dyes (ERDs) for an efficient energy transfer to the N719 dye in I(-)/I3(-) based liquid-junction dye-sensitized solar cells (DSSCs). The introduction of the ERDs, either as an additive in the electrolyte or as a co-adsorbent, greatly enhanced the power conversion efficiencies (PCEs), mainly because of an increase in short-circuit current density (Jsc). This was attributed to the effects of non-radiative Förster-type excitation energy transfer as well as the radiative (emission)-type fluorescent energy transfer to the sensitizers. The net PCEs for the N719-sensitized DSSCs with DAPI and H33342 were 10.65% and 10.57%, and showed an improvement of 12.2% and 11.4% over control devices, respectively.
4',6-二脒基-2-苯基吲哚（DAPI）和Hoechst 33342（H33342）被用作新型能量中继染料（ERD），用于在基于I⁻/I₃⁻的液结染料敏化太阳能电池（DSSC）中向N719染料进行高效能量转移。将ERD作为添加剂添加到电解质中或作为共吸附剂引入，极大地提高了功率转换效率（PCE），这主要是由于短路电流密度（Jsc）增加所致。这归因于非辐射福斯特型激发能量转移以及向敏化剂的辐射（发射）型荧光能量转移的作用。含DAPI和H33342的N719敏化DSSC的净PCE分别为10.65%和10.57%，与对照器件相比分别提高了12.2%和11.4%。
