Project Description

Organic perovskite materials are touted to be promising photoactive materials relevant for fabrication of thin film photovoltaic (PV) devices for of efficient, cheap and safe solar-cell technology. However their hygroscopic nature, thermal sensitvity, and degradation pose practical, commercial challenges. In this project, This team hence allows the development of (i) Encapsulation that can offer a thermal barrier that can prospectively enhance the life of organic perovskites, (ii) Perovskite solar cell devices, wherein the compositions are tuned to make it relevant for technology (Internal photocurrent efficiency >12 %). (iii) Deepened understanding of the roles of the encapsulating material, and development of design rules for improving organic perovskite active material. (iv) Computational studies, simulations and spectroscopic analysis in ELI-ALPS will enhance understanding of the materials and their performance, and also offer insights on means to improve.
