采用一种低成本、无真空的叠层工艺制备了半透明聚合物基太阳能电池。这一过程是在透明的银膜上沉积导电胶溶液，然后与有源层叠层。使用胶水溶液和聚(3，4-乙二氧基噻吩基)：聚苯乙烯磺酸(PEDOT：PSS)和邻山梨醇的混合物。为了进一步提高这些电池的转换效率，我们研究了导电胶层的主要因素与光伏性能之间的关系。结果表明，在导电胶层厚度的一定范围内，光伏特性与导电胶的导电性关系不大，而与接触面积有很强的相关性。优化后的电池在正面和背面100 mW cm(-2)AM1.5G反光纸照射下的功率转换效率分别为2.22%和2.41%。
Semitransparent polymer-based solar cells were fabricated by using a low-cost, vacuum-free lamination process. This process is to deposit a conductive glue solution on the transparent Ag film, followed by lamination with the active layer. The glue solution and a mixture of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) and o-sorbitol was used. To allow future improvements in the conversion efficiency of these cells, we investigated the relationship between major factors of the conductive glue layer and photovoltaic property. As a result, it was suggested that photovoltaic property had less of a relation to conductivity of the conductive glue layer but a strong correlation with the contact area within a certain range of the film thickness of the conductive glue layer. The optimized cells exhibited 2.22% and 2.41% of power conversion efficiencies during front and backside 100 mW cm(-2) AM1.5G illumination with reflection paper, respectively.
