Organic/inorganic hybrid solar cells have attracted much attention with simple fabrication and high performance because the combination of organic and inorganic materials compensates their disadvantages each other. This work tried to realize highly efficient hybrid solar cell based on crystalline Si and poly(3,4‐ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) junction. Performance dependences on the resistivity of Si substrate and the thickness of PEDOT:PSS layers were analyzed. Photocurrent of hybrid solar cells strongly depended on Si substrate, while overall performance depended on total resistance of hybrid solar cells not Si substrate. The charge transfer of PEDOT:PSS layer was varied by its thickness, and the 30‐nm‐thick PEDOT:PSS layer showed the best characteristics of charge transfer. The conductivity of the PEDOT:PSS layer was finally improved by solvent treatment using acetonitrile. As a result, the photovoltaic performance was much enhanced, and it was defined by 0.56 V of VOC, 30.24 mA/cm2 of JSC, 0.68 of FF, and 11.52% of efficiency.

基于最佳电阻Si和溶剂改性聚（3,4-乙烯二氧噻吩）聚（苯乙烯磺酸盐）结的有机/无机混合太阳能电池光伏性能的研究进展
有机/无机混合太阳能电池以其简单的制造和高性能而备受关注，因为有机材料和无机材料的组合可相互弥补其缺点。这项工作试图实现基于晶体硅和聚（3,4-乙撑二氧噻吩）聚（苯乙烯磺酸盐）（PEDOT：PSS）结的高效混合太阳能电池。分析了性能对硅衬底电阻率和PEDOT：PSS层厚度的依赖性。混合太阳能电池的光电流强烈依赖于Si衬底，而整体性能取决于混合太阳能电池而不是Si衬底的总电阻。PEDOT：PSS层的电荷转移因其厚度而异，厚度为30 nm的PEDOT：PSS层表现出最佳的电荷转移特性。PEDOT的电导率：通过使用乙腈的溶剂处理，最终改善了PSS层。结果，光伏性能大大提高，其定义为V的0.56 VOC，J SC为30.24 mA / cm 2，FF为0.68，效率为11.52％。
