Abstract
The limit photoconversion efficiency of silicon solar cells is calculated assuming Lambertian light trapping of the incident solar radiation with AM1.5 G spectrum. Fresnel reflection of the trapped photons from the front surface has been neglected in the previous works. Here, a more accurate absorptance expression is used with Fresnel reflection properly included. As a result, a new photoconversion efficiency limit of 29.99% is found. It exceeds the latest reported value by as much as 0.27%-abs.
