Photovoltaic performance of pulsed laser deposited 2d transition metal dichalcogenides thin films

Abstract

Dye sensitized solar cells dsscs are one among the promising devices in the family of solar cells the thematic path of developing the solar cells focuses on high efficiency stability and low cost a perfect device should meet out these golden triangle issues in the fabrication of dsscs the conventional counter electrode material platinum pt increases the cost of the device and also has a drawback of being corroded easily hence to reduce the cost of the device as well as to hold the catalytic activity in the dsscs researchers are working in the development of new cost effective and alternative materials relying upon the reports of structure based applications of graphene two dimensional transition metal dichalcogenides 2d tmds owing to their unique porous layered nanostructure and as well as other properties are emerging as a new class of materials to be used in dsscs these materials are characterized by unique 2d structure of trigonal prismatic metal centers with interlayer chalcogen bonding among the various tmds mos2 and ws2 are interesting due to their similar physical and chemical properties. newline
