In this work, we have investigated the interaction of hydrothermally synthesized Zn₂SnO₄ (ZTO) nanoparticles (NPs) with two different commercial photo sensitizers such as N719 and N3 dye molecules and studied their performance in dye sensitized solar cells (DSSC). Interestingly, the ZTO NPs exhibited band edge emission in the mid UVA region and as a result possibility of enhanced light harvesting in the terminal UVA region was anticipated in the device due to the efficient energy transfer observed in case of the sensitizer N719 than N3. The dye sensitization property has been found to be higher for the N3 dye molecules than the N719 dye molecules as based on the time dependent dye loading study. The devices fabricated with ZTO-N719 exhibited improved photovoltaic performance compared to the ZTO-N3 based devices exhibiting an overall conversion efficiency of 2.56% by the former compared to the later (1.90%) under 1SUN 1.5AM illumination and sensitization for 12 h.

在这项工作中，我们研究了水热合成的Zn ₂ SnO ₄的相互作用（ZTO）具有两种不同的商业光敏剂（例如N719和N3染料分子）的纳米颗粒（NPs），并研究了它们在染料敏化太阳能电池（DSSC）中的性能。有趣的是，ZTO NP在UVA的中部区域表现出能带边缘发射，由于在N719敏化剂的情况下观察到了有效的能量转移，因此预期在设备的终端UVA区域中增强了光收集的可能性。根据时间相关的染料负载研究，已发现N3染料分子的染料敏化特性高于N719染料分子。与基于ZTO-N3的器件相比，用ZTO-N719制成的器件表现出更高的光伏性能，在1SUN 1下，前者的整体转换效率为2.56％，而后者为1.90％。
