Here, we present a new DSSC design, consisting of sequential QDs and dye sensitization layers, that opens the path toward high optical density DSSCs that cover a significant part of the solar spectrum. The new configuration is enabled by the application of an amorphous TiO2 layer between the two sensitizers, allowing both electron injection from the outer absorber and fast hole extraction from the inner sensitizing layer. Utilizing two sensitizing layers, we obtain a 250% increase in cell efficiency compared to a QD monolayer cell.
在此，我们展示了一种新型染料敏化太阳能电池（DSSC）设计，它由连续的量子点（QD）和染料敏化层组成，为实现高光密度的DSSC开辟了道路，这种DSSC能够覆盖太阳光谱的很大一部分。通过在两种敏化剂之间应用非晶TiO₂层实现了这种新配置，这既允许电子从外层吸收体注入，又能实现从内层敏化层快速提取空穴。利用两层敏化层，与量子点单层电池相比，我们使电池效率提高了250%。
