Performance of dye-sensitized solar cell based on metal-deposited BiFeO3 nanoparticles

Abstract

The supply of clean, green and environment friendly energy to our society is a matter of great concern for the scientific communities, as the non-renewable resources such as gas; coal and oil are limited and for sure will run out with time. Solar energy is one of the most promising alternative energy resources. Therefore, today much attention has been paid on dye-sensitized solar cells (DSSCs) in the both academic and industrial platforms as an alternative clean and green energy resource precisely because of their relatively high energy conversion efficiency, low production cost, low manufacturing toxicity, ease of fabrication and flexibility. Advances in this field have been achieved by improving the energy conversion efficiency, by extensively studying the mechanism to enhance electron generation, injection or transfer to semiconductors and reduction in the charge recombination processes. In the light of above, in the present study DSSC has been fabricated using bare and Au decorated BiFeO3 nanoparticles. The synthesized nanoparticles show excellent energy conversion efficiency around 2.99%. The synthesized materials have wide range of application in the futuristic photovoltaic devices.
