A general analytical solution to one-dimensional minority-carrier transport under illumination in uniformly doped light-trapping (LT) Si solar cells in low-level injection is presented, which is valid for any constant value of propagation angle of internal light, θ. This solution individuates an exact relationship between devices where θ = 0° and devices where θ > 0°. This relationship allows checking the new solution numerically. The numerical check is performed successfully at standard Lambertian optics (θ = 60°) by calculating light-generated currents in a set of Si solar cells. © 2016 Elsevier Ltd.

Abstract
A general analytical solution to one-dimensional minority-carrier transport under illumination in uniformly doped light-trapping (LT) Si solar cells in low-level injection is presented, which is valid for any constant value of propagation angle of internal light, θ. This solution individuates an exact relationship between devices where θ = 0° and devices where θ > 0°. This relationship allows checking the new solution numerically. The numerical check is performed successfully at standard Lambertian optics (θ = 60°) by calculating light-generated currents in a set of Si solar cells. © 2016 Elsevier Ltd.File in questo prodotto:
