Influence of an Additional P3HT Layer on the Performance of P3HT: IC60BA Polymer Solar Cell

A simulation study utilizing SCAPS 1-D software was conducted to explore the effects of an additional P3HT (Poly 3-hexylthiophene) layer on the performance of bulk heterojunction polymer solar cells, specifically with the active layer P3HT: IC60BA. The investigated cell structure is ITO/PEDOT:PSS/P3HT/P3HT:IC60BA/ZnO NPs/Al. Following the standardization of the software, we determined the optimal parameters of the solar cell structure by analyzing various factors influencing cell performance across different layers. Subsequently, after optimizing the structure, the power conversion efficiency (PCE) improved significantly, rising from 5.18% without additional layer to 15.26% with additional layer.
