Title:
EFFICIENCY ENHANCEMENT OF SOLAR CELLS USING LIGHT MANAGEMENT
Document Type and Number:
WIPO Patent Application WO/2010/104890
Kind Code:
A3
Abstract:
A photovoltaic cell (110) includes a junction, formed from an n-type semiconductor material and a p-type semiconductor material, a trench, (120) opening toward the light-incident side of the junction, for trapping reflected light, and two photon conversion layers (132,139) A first photon conversion layer (132) arranged at the light-incident side of the junction, converts photons from a higher energy to a lower energy suitable for absorption by the semiconductor material, and a second photon conversion layer (134) arranged at the opposite side of the junction, converts photons from a lower energy to a higher energy suitable for absorption by the semiconductor material.
