Abstract: The absorption coefficient of silicon for infrared light is very low and most solar cells absorb very little of the infrared light energy in sunlight.

Backside texturing with diffusive scattering and with a smooth front surface of the solar cell results in multiple internal reflections, light trapping, and a large enhancement of the absorption of infrared solar energy.
