摘　　要：采用半透明有机太阳能电池和铜锌锡硫硒太阳能电池构成四端串联太阳能器件,并且利用表面具有微型金字塔结构的微米聚二甲基硅氧烷(PS-PDMS)膜的减反射作用来提高太阳能电池的效率。为了研究PS-PDMS的尺寸和放置位置对四端串联太阳能电池性能的影响。制备了尺寸分别为18μm、14μm和9μm微型金字塔结构的PS-PDMS薄膜,比较了不同尺寸下PS-PDMS薄膜的减反射效果,发现9μm尺寸的PS-PDMS薄膜的减反射效果最好。将9μm尺寸的PS-PDMS薄膜用在四端串联太阳能电池的底电池时,四端串联太阳能电池具有最佳效率。最终获得了效率为11.26%的四端串联太阳能电池。与单结铜锌锡硫硒太阳能电池相比,四端串联太阳能电池的最佳效率提高了27.51%。4-T tandem solar cells was constituted of a semi-transparent organic solar cells and the Cu_(2)ZnSn(S,Se)_(4) solar cells.The anti-reflection of the pyramidal micron polydimethylsiloxane(PS-PDMS)was applied to trap the sunlight.The impact of size and position of PS-PDMS on the performance of 4-T tandem solar cells were analyzed.The width size of the micro-pyramidal structure was various of 9~18μm,and the results showed that 9μm width of PS-PDMS films could achieve the most significant anti-reflection effect when it was pasted on the bottom cell of 4-T tandem solar cells.11.26% PCE of the 4-T tandem solar cells was obtained.Compared with that of the single Cu_(2)ZnSn(S,Se)_(4) solar cells,the optimal PCE of 4-T tandem solar cells increased by 27.51%.
