Limiting Light Escape Angle in Silicon Photovoltaics: Ideal and Realistic Cells

Restricting the light escape angle within a solar cell significantly enhances light trapping, resulting in potentially higher efficiency in thinner cells. Using an improved detailed balance model for silicon and neglecting diffuse light, we calculate an efficiency gain of 3% abs for an ideal Si cell...
