Abstract A major challenge in thermoelectrics (TEs) is developing devices made of sustainable, abundant, and non‐toxic materials. Furthermore, the technological drive toward low sizes makes crucial study nano micro configurations. In this work, thin film TE based on p‐type Cu 2+ x Zn 1‐ SnS 4 SnSe , n‐type Al y O are fabricated by physical vapor deposition. The kesterite phases show good purity promising power factor, likely enhanced copper–zinc order–disorder transition. Thin generators...
Abstract Perovskite solar cells (PSCs) have shown a significant increase in power conversion efficiency (PCE) under laboratory circumstances from 2006 to the present, rising 3.8% an astonishing 25%.
