Solution-processed In2S3 buffer layer for chalcopyrite thin film solar cells

Solution-processed In2S3 buffer layer for chalcopyrite thin film solar cells

We report a route to deposit In2S3 thin films from air-stable, low-cost molecular precursor inks for Cd-free buffer layers in chalcopyrite-based thin film solar cells. Different precursor compositions and processing conditions were studied to define a reproducible and r...
