双尺寸CdS量子点被用作太阳能电池的光收集器，以实现高功率转换效率。采用化学浴沉积和退火处理制备不同尺寸的量子点。研究发现，双尺寸 CdS 量子点的共敏化策略可以通过形成 I 型能带结构来有效提高太阳能电池的性能。我们的工作表明，量子点的合理配置对于提高太阳能电池的性能至关重要。
Dual-sized CdS quantum dots were employed as light harvesters of solar cells to achieve high power conversion efficiency. Chemical bath deposition and annealing treatment were adopted to produce quantum dots with different sizes. The strategy of cosensitization by dual-sized CdS quantum dots was found effective to improve the performance of solar cells by forming a type-I band structure. Our work indicates that a reasonable configuration of quantum dots is crucial on boosting the performance of solar cells.
