Electro-Luminescent and Photovoltaic Responses of poly (propylene imine) dendritic CuInSe2 (CIS) Quantum Dots

Abstract

The development of renewable energy has attracted more attention due to the increasingly serious energy and environmental crisis in the world nowadays. Second generation photovoltaics based on thin films of binary semiconductor nanocrystals such as cadmium sulphide (CdS), cadmium selenide (CdSe), cadmium telluride (CdTe), lead sulphide (PbS) and lead selenide (PdSe), have shown considerable potential with their power conversion efficiencies (PCEs) improving from 0,1 % to about 6-7% within a space of 2 years.
