The importance for nanostructures in N-I-P ambiguously defined Si periodic concentrated solar devices

Abstract

Arrays of periodic one-dimensional nano materials provide light–matter interaction in terms of tunable optical properties which are attractive for planning efficient optoelectronic devices. This paper is based on n-i-p thin-film amorphous silicon utilizes scaffolds of vertically aligned carbon nanotube (CNT) array for a fabrication of bottom-up grown Nano pillar (NP) array solar cells. The varying effect of the CNT extent over a wide range from 800 to 2000 nm on electrical properties of the solar cells and optical were examined. The NP solar cell with CNT extent over a range of 800 nm show ‘moth-eye’ broadband antireflection effort and the value 10% lower than an average reflectance. The enhanced optical absorption relocates to significant enhancements in quantum efficiency and photocurrent contrast to a conventional planar solar cell under low light circumstances. The open-circuit voltage (Voc) of the NP solar cell was established uniformly correlated with the illumination condition and CNT spacing. The main importance is to develop high efficiency one-dimensional nanostructured solar cells results were presented here.
