Abstract
Window- or building-integrated semi-transparent solar cells are particularly interesting applications for organic photovoltaic devices. In this work, we present an easy-to-process inverted device architecture comprising fully solution processable poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) bilayer top-electrodes for efficient semi-transparent organic solar cells. By incorporating dyes with a complementary absorption to the light harvesting polymer poly[[9-(1-octylnonyl)-9H-carbazole-2,7-diyl]-2,5-thiophenediyl-2,1,3-benzothiadiazole-4,7-diyl-2,5-thiophenediyl] (PCDTBT) into the PEDOT:PSS electrode, we achieve fully color neutral transparency perception and a color rendering index approaching 100. This makes the devices suitable for applications such as window shadowing or the integration into overhead glazing.
