作为染料敏化太阳能电池的一个分支，量子点敏化太阳能电池（QDSSC）由于其导带电子密度高而受到人们的广泛关注。本文报道了高效In2S3敏化太阳能电池的合成。重复吸附循环以优化In2S3负载并因此优化光伏性能。在24个循环的In_2S_3吸附下，获得了1.30%的能量转换效率（AM 1.5G下）。相对高的转换效率结合简单的制备证明了In2S3量子点在QDSSC中的潜在用途。
As a branch of dye − sensitized solar cell, quantum dot − sensitized solar cells (QDSSCs) have attracted growing interests because of promisingly theoretical electron density on conduction band of TiO2nanocrystallite. Here we report the synthesis of efficient In2S3sensitized solar cells. The adsorption cycles are repeated to optimize In2S3loading and therefore photovoltaic performances. A promising power conversion efficiency of 1.30% (under AM 1.5G) is recorded at 24 cycles of In2S3adsorption. The relatively high conversion efficiency in combination with simple preparation demonstrates the potential use of In2S3quantum dots in QDSSCs.
