The Research of Flexible Solar Cells for Application in Solar Roof

Abstract

In this paper, we report the deposition of nano-crystalline silicon flexible solar cells on stainless steel (SS) substrates for application in solar roof. The influence of substrate treatment on the properties of material and the solar cells was studied by Raman spectroscopy, scanning electron microscope, current-voltage (I-V), and Quantum efficiency (QE) measurements. Results suggest that the properties of the Si:H thin films and solar cells were greatly improved by the substrate treatment with surface polishing and the followed Ag/ZnO electrodes deposition.
