Additionally, the use of solar batteries can help to reduce energy waste. When excess solar energy is generated but not used or stored, it is often lost, meaning that energy is wasted. By using solar batteries to store this excess energy, it can be used later when needed, reducing waste, and maximizing the efficiency of the solar panel system.
Recently, the anomalous photovoltaic (PV) effect in BiFeO3 (BFO) thin films, which resulted in open circuit voltages (Voc) considerably larger than the band gap of the material, has generated a revival of the entire field of photoferroelectrics. Here, via temperature-dependent PV studies, we prove that the bulk photovoltaic (BPV) effect, which has …
