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...

Too Many Junctions?: A Case Study of Multijunction Thin-Film Silicon Solar Cells

The benefit of two-terminal multijunction solar cells in regard to the number<br/>of junctions (subcells) is critically evaluated. The optical and electrical losses<br/>inherent in the construction of multijunction cells are analyzed using information<br/>from thin-film silicon photovoltaics as a representative case. Although<br/>the...
