Fabrication and performance analysis of new metal oxide mwcnt nanocomposite heterojunction solar cells

Abstract

Solar cells can be a viable solution for the rising energy demand newlineand global warming. But the cost and complex methodologies involved in the newlinefabrication of solar cells remain the main obstacles for proliferation of solar newlinecells. A facile and low-cost method for construction of solar cells with newlineappreciable efficiencies has been attempted. Carbon Nanotubes (CNT) are newlineexcellent materials with wide optical absorption, tenability, low resistance newlineand high charge carrier mobility, making them ideal candidates for newlinephotovoltaic applications.In this work, an attempt has been made to fabricate new newlineheterojunction solar cells, with metal oxide as the window layer and metal newlineoxide ingrained MWCNT (MWCNT:MO) as the active absorber layer. In this newlinenew heterojunction solar cells, MWCNT impart good carrier mobility and newlinehigh absorption and the metal oxide improve the open circuit potential. For newlinecomparison, metal oxide - metal oxide heterojunction solar cells and newlineMWCNT-metal oxide heterojunction solar cells, MWCNT-metal oxide newlineheterojunction solar cells with metal oxide interfacial layers have been newlinefabricated and tested. Finally, the thickness of the absorber layer of the newlinechampion solar cell has also been optimised to yield higher efficiencies. newline newline
