Semi-transparent organic solar cells (ST-OSCs) have a great attention for their potential applications in various ways, such as building-integrated photovoltaics (BIPVs), greenhouse roof, etc. ST-OSCs have been studied for enhancing performance and transparency. But they still have weak absorption and poor surface properties. In this study, we fabricated ST-OSCs by introducing the multi-layer structure suitably. We controlled photoactive layer using interdiffusion method with polymeric additives for improving the device's performance. The polmeric additives play a key role of rearrangement film-forming in Multi-layer boosting charge transportation simply. These works showed that device's transmittance and high efficiency through the Multi-layer technique.
