Abstract

Tandem solar cells with silicon as one of its constituents have flat surfaces (surfaces without texturing). That is why flat surfaces Solar cells have got quite importance. But the issue with the flat surfaces is the high reflection loss (flat) and poor light trapping (no-texturing) in the cells. So, some scattering film, other than direct texturing, that is polydimethylsiloxane (PDMS) polymer with the texture is used. The optimized PDMS film here is the random pyramidal film because random pyramidal PDMS films have a drop of 56.6% (from 33.54 to 14.48 %) in reflectance used on polished Silicon while iso-textured and inverted pyramids have 51.55% (33.54 to 16.25%) and 48.47% (from 33.54 to 17.28%) respectively. This PDMS film with random textures when applied to 2-terminal monolithic perovskite/Silicon tandem, its external quantum efficiency shows an increase of 1.16mA/cm2 in the short-circuit current and reflection loss reduces by 4.1 mA/cm2.
