Using photoluminescence, implied open-circuit voltage imaging for perovskite solar cell field testing

To evaluate the outdoor performance and stability of perovskite solar cells using contactless and noninvasive methods, an Australian and Chinese research team found a way to use photoluminescence imaging as well as demonstrating a proof of concept for implied open-circuit voltage (iVOC) imaging. Their research relied on cost-effective equipment that operates under direct sunlight. To monitor and assess perovskite solar cells' stability and performance operating outdoors in a contactless way, a team led by researchers from the University of New South Wales (UNSW) in Australia demonstrated a solution ...
