Scientists from the Institute for Open and Transdisciplinary Research Initiatives at Osaka University discovered a new feature of solar cells made from antimony sulfiodide:sulfide composite, which they termed the wavelength-dependent photovoltaic effect (WDPE). The team determined that changing the color of incident light from visible to ultraviolet induced a reversible change in the output voltage, while leaving the current generated unchanged. This work may lead to new functional light-sensing and imaging devices.
