In this paper,we have reported the synthesis of FeS_2 of higher band gap energy(2.75 eV) by using capping reagent and its successive application in organic-inorganic based hybrid solar cells.Hydrothermal route was adopted for preparing iron pyrite(FeS_2) nanoparticles with capping reagent PEG-400.The quality of synthesized FeS_2 material was confirmed by X-ray diffraction,field emission scanning electron microscopy,transmission electron microscopy,Fourier transform infrared,thermogravimetric analyzer,and Raman study.The optical band gap energy and electro-chemical band gap energy of the synthesized FeS_2 were investigated by UV-vis spectrophotometry and cyclic voltammetry.Finally band gap engineered FeS_2 has been successfully used in conjunction with conjugated polymer MEHPPV for harvesting solar energy.The energy conversion efficiency was obtained as 0.064%with a fill-factor of 0.52.
