Semitransparent organic solar cells (ST-OSCs) have promising prospects for building or vehicle integrated solar energy harvesting with energy generation and see-through function. How to achieve both an adequate average visible transmittance (AVT) and high-power conversion efficiency (PCE) is always the key issue.
Herein, a simple but effective strategy for constructing high performance ST-OSCs by introducing a small molecule [2-(9-H-Carbazol9-yl) ethyl] phosphonic acid (2PACz) into a low-donor content active layer is reported.
The TPV technique using Paios was based on monitoring the photovoltage decay upon a small optical perturbation during different constant bias light-intensity. As were dark C–V measurements.
