Abstract

In order to improve the power conversion efficiency (PCE) of Cu(In,Ga)Se (CIGS) solar cells, a BaTiO (BTO) layer was inserted into the Cu(In,Ga)Se. The performances of the BTO-coupled CIGS solar cells with structures of Mo/CIGS/CdS/i-ZnO/AZO, Mo/BTO/CIGS/CdS/i-ZnO/AZO, Mo/CIGS/BTO/CdS/i-ZnO/AZO, Mo/CIGS/CdS/BTO/i-ZnO/AZO, Mo/CIGS/BTO/i-ZnO/AZO, Mo/CIGS/CdS/BTO/AZO, and Mo/ CIGS/CdS(5 nm)/BTO(5 nm)/i-ZnO/AZO were systematically studied via the SCAPS-1D software. It was found that the power conversion efficiency (PCE) of a BTO-coupled CIGS solar cell with a device configuration of Mo/CIGS/CdS/BTO/AZO was 24.53%, and its open-circuit voltage was 931.70 mV. The working mechanism for the BTO-coupled CIGS solar cells with different device structures was proposed. Our results provide a novel strategy for improving the PCE of solar cells by combining a ferroelectric material into the - junction materials.

摘要

为了提高铜铟镓硒（CIGS）太阳能电池的功率转换效率（PCE），在铜铟镓硒（CIGS）中插入了一层钛酸钡（BTO）。通过SCAPS - 1D软件系统研究了具有Mo/CIGS/CdS/i - ZnO/AZO、Mo/BTO/CIGS/CdS/i - ZnO/AZO、Mo/CIGS/BTO/CdS/i - ZnO/AZO、Mo/CIGS/CdS/BTO/i - ZnO/AZO、Mo/CIGS/BTO/i - ZnO/AZO、Mo/CIGS/CdS/BTO/AZO以及Mo/CIGS/CdS(5 nm)/BTO(5 nm)/i - ZnO/AZO结构的BTO耦合CIGS太阳能电池的性能。结果发现，具有Mo/CIGS/CdS/BTO/AZO器件结构的BTO耦合CIGS太阳能电池的功率转换效率（PCE）为24.53%，其开路电压为931.70 mV。提出了不同器件结构的BTO耦合CIGS太阳能电池的工作机制。我们的结果为通过将铁电材料结合到p - n结材料中来提高太阳能电池的功率转换效率提供了一种新策略。
