Abstract

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.
