摘      要：In this paper,we have reported the synthesis of FeS2 of higher band gap energy（2.75 eV） by using capping reagent and its successive application in organic-inorganic based hybrid solar *** route was adopted for preparing iron pyrite（FeS2） nanoparticles with capping reagent *** quality of synthesized FeS2 material was confirmed by X-ray diffraction,field emission scanning electron microscopy,transmission electron microscopy,Fourier transform infrared,thermogravimetric analyzer,and Raman *** optical band gap energy and electro-chemical band gap energy of the synthesized FeS2 were investigated by UV-vis spectrophotometry and cyclic *** band gap engineered FeS2 has been successfully used in conjunction with conjugated polymer MEHPPV for harvesting solar *** energy conversion efficiency was obtained as 0.064%with a fill-factor of 0.52.
