Investigation of bacterial pigment from Serratia nematodiphila as a sensitizer for a nanostructured solar cell

Dye sensitized solar cells have proven its potential as affordable, green method of turning energy into electrical energy. This article presents an extensive comparative study on dye with two types transport layers made ZnO nanorods and TiO2 mesoporous film, wherein bacterial pigment extracted from microorganism Serratia nematodiphila strain B2 is employed a sensitizer. For performance enhancement via the plasmonic effect, Ag nanoparticles been deposited onto conducting glass used counter electrode (CE). The efficiency fill factor (averaged over 3 readings) are found to be approximately 2% 43%, respectively, film 0.4% 25%, nanorod in designed DSSCs. Experiments conducted for ten weeks evaluate stability pigment. findings suggest that pigments may possibly replace dyes, creating new category known biopigment-sensitized cells.
