<p>➀ Researchers from ETH Zürich and Empa developed a perovskite-based image sensor that captures more light with better color accuracy and fewer artifacts compared to traditional silicon sensors; </p><p>➀ The stacked perovskite layers enable full-spectrum light absorption without filters, tripling both light capture and resolution potential; </p><p>➀ The technology shows promise for hyperspectral imaging in medical diagnostics, environmental monitoring, and machine vision applications, with plans to miniaturize pixels further for commercialization.</p>
