On the bright side: A solution-based strategy was developed for in situ synthesis and film deposition of Cu2ZnSnSe4 nanocrystal films (samples a-d). The obtained Cu2ZnSnSe4 nanocrystal films can be used as an effective counter-electrode (CE) material to replace Pt, and yield low-cost, high-efficiency dye-sensitized solar cells (DSSCs). The assembled solar cell devices exhibit an efficiency of 7.82 % under 1 sun irradiation (see figure).
积极的一面是
开发了一种基于解决方案的策略，用于原位合成和薄膜沉积 Cu2ZnSnSe4 纳米晶薄膜（样品 a-d）。所获得的 Cu2ZnSnSe4 纳米晶薄膜可用作有效的对电极 (CE) 材料来替代 Pt，并产生低成本、高效率的染料敏化太阳能电池 (DSSC)。组装后的太阳能电池器件在 1 个太阳光照射下的效率为 7.82%（见图）。
