A Novel Architecture to Improve Performance of Photovoltaic Cells using Lens Let Arrays

Abstract

The Green revolution as ushered in by the photovoltaic cells is all pervasive. Power production through photovoltaic cells is gaining momentum as it reduces the Green House Effect. But the photovoltaic cells are plagued by severe efficiency deficiencies. It is at only 40% to 50%. In this novel approach the author proposes a new technique of using lens let arrays in combination with a resonance cavity to improve the efficiency of the photovoltaic cells. The lens in a lens let array brings the Sun’s radiation in the form of light energy to a focus on the photovoltaic cell. Since this increases the Intensity of the radiation at the PV cell surface the effective conversion rate of Photon to Electron increases. Consequently the output current increases thereby improving the performance of the photovoltaic cell.
