Solar and indoor photovoltaic

Our team began with dye-sensitized solar cells (DSSC) and is now working on perovskite solar cell (PSC) for solar and indoor light harvesting. Metal halide perovskite solar cell is a promising candidate for solar photovoltaic conversion due to its high absorption coefficient, long carrier lifetime, low recombination rate, and outstanding power conversion efficiency. In addition to solar photovoltaics, we are interested in using PSC for indoor photovoltaics to power billions of wireless devices for a future Internet of Things (IoT) nodes, of which the self-powered characteristic can reduce the use of batteries and avoid battery replacement.
