Abstract :
This paper provides a comprehensive guideline to design high efficient Si thin film solar cells via surface periodic Si nanopillars (SiNP) array texturing. A power conversion efficiency of ~18.1% is predicted to be achievable for the cell consisting of the SiNP array (array periodicity of 500 nm, SiNP diameter of 250 nm, and SiNP length of 1000 nm) on 800 nm thick underlying Si film based on the optical and electrical calculations.
