Investigation of device performance due to inclusion of Ru and Pt based heavy metals in organometllic solar cells

Conjugated polymers doped with metal ions offer superior material properties in the development of next generation flexible PV technology [1]. Charge transport mechanism in metallated conjugated polymer with different solvent processing was described by A.F. Mitul in [1]. In this work, the modification of heavy metals e.g, Pt, Ru etc in organometllic solar devices are investigated. The variation in device performance i.e, open circuit voltage (Voc), external quantum efficiency (EQE) is explained in the light of nano scale morphology. Change of heavy metals in organicchemical structure provides differences in nanoscale morphology and hence, it describes the favorable condition for optimum device performance.
