英文摘要	Some ferroelectric materials have demonstrated both pyroelectric and photovoltaic effects for scavenging thermal and solar energies. However, how to couple pyroelectric and photovoltaic effects in ferroelectric materials remains a challenge. Here, a ferro-pyro-phototronic effect based on coupling pyroelectric and photovoltaic effects has been utilized to enhance the photocurrent in a ferroelectric BaTiO3-based ﬂexible photodetector system. As compared with a purely photovoltaic system, the corresponding current peak and plateau were 451.9% and 17.2% higher in the coupled photovoltaic-pyroelectric system, respectively. The results can be explained by ferro-pyro-phototronic effect with an induced energy band bending. As a demonstration of its potential application, we developed a sensing system that is suitable for detecting and recognizing both light and temperature variations by recording the electrical signals mapped as an array. ; Some ferroelectric materials have demonstrated both pyroelectric and photovoltaic effects for scavenging thermal and solar energies.
