Abstract

In this work we report 23% increase in efficiency of n-i-p a-Si:H cells using Si, InN and Au nanoparticles. These cells shows an average improvement of 24.54% in short circuit current. The coated cells also reduce the reflection by 2.7% compared to reference cell between 300-800 nm, which indicates light is getting scattered by these nanoparticles. EQE and IQE analysis show that the overall enhancement can be attributed to photon energy downshifting with a reduction in reflectivity.
