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