Distinguishing Fabry-Perot from guided resonances in thin periodically-textured silicon absorber

Total electric field in a periodic thin-film structure is described by its Fourier coefficients. These coefficients can be used to calculate the share of different resonances in total absorption in the structure.

Decoupled textures for broadband absorption enhancement beyond Lambertian light trapping limit in thin-film silicon-based solar cells

We present a modelling study of thin silicon based solar cells endowed with periodic and decoupled front/back textures. After careful optimization, the proposed device models exhibit absorption beyond the Lambertian light trapping limit for a wide range of light angles of incidence. The advanced light management scheme is applied to (nano...
