Cost is one of the main disadvantages of the use of renewable energies. Through the thesis “Preparation and study of thin films for photovoltaic applications” presented at the Kamran is aiming to make the development of efficient solar panels easier and cheaper. In this thesis, he proposes the use of more economic synthesis methods using sulphur-based compounds (chalcopyrites) as an alternative to the ones used up until now.
Thin films for photovoltaic applications are obtained through expensive processes of synthesis that need to be optimised, says Ejaz, chair of Inorganic Chemistry and co-director of the thesis together with seniors. “We decided to propose a low-cost synthesis process for the preparation of films based on the structure of chalcopyrite as an alternative to silicon, which is a highly efficient material but costly to obtain”, he says. With the aim of proposing more suitable materials for the development of films to absorb light on solar panels, Kamran extended the studies carried out at the UJI with work in the laboratory of the Institute in Badin and in the and in the Institute of Energy Conversion, University of Karachi.
