This paper present an experimental study on a new dry transfer method of graphene applied as transparent conducting electrode in textured silicon solar cells. Raman spectra of dry exfoliated graphene indicated a monolayer graphene was transferred onto textured Si cells and the dry exfoliated graphene with better crystalline quality is attained. Photovoltaic result shows the short circuit current of the dry transferred graphene on texture Si solar cell has an increase of 28% compared to the wet transferred graphene. It proves the possibility of dry transferred graphene as transparent conducting electrode in textured Si solar cell applications.
