Band Engineering News Today

Hydrogen (H2) production through water splitting using sustainable energy sources is gaining increasing attention. However, limited catalytic performance based on a single driving force presents both opportunities and challenges for achieving a high-efficiency H2 output. Exploring multiple driving sources to enhance the comprehensive catalytic performance shows great promise. BiFeO3 (BFO), with features of narrow band gap and ultrahigh ferroelectric polarizations, is considered as a promising al...

Photovoltaic energy as one of the important alternatives to traditional fossil fuels has always been a research hot spot in the field of renewable and clean solar energy. Very recently, the anomalous ferroelectric photovoltaic effect in multiferroic bismuth ferrite (BiFeO3) has attracted much attention due to the above-bandgap photovoltage and switchable photocurrent. However, its photocurrent density mostly in the magnitudes of μA/cm2 resulted in a poor power conversion efficiency, which sever...
