Abstract
A method of fabricating a low-cost, flexible and highly efficient photovoltaic device. The method includes providing a layer of thin film, shaping the thin film into a plurality of parabolic shaped concentrators, forming an aperture in the bottom of each of the parabolic shaped concentrators, coating the concentrators with a reflective material, encapsulating the concentrators with a transparent insulating layer, depositing a photovoltaic cell on the bottom parabolic shaped concentrators, and depositing an anti-reflection coating on the top of the parabolic shaped concentrators.
