Jeyakumar, R.; Maiti, T. K.; Khader, Mahmoud M.; Kandasamy, Nikesh; Verma, Amit; Nekovei, Reza; Kumar, J.; Balaji , Nagarajan; Yi, Junsin... more authors ... less authors ( Springer New York LLC , 2017 , Article)We report on the modeling and performance optimization studies of point contact back heterojunction (BHJ) solar cells. BHJ solar cell technology is a combination of front heterojunction (a-Si:H/c-Si) solar cell technology ... -
Simulation study of Schottky contact based single Si wire solar cell
Rabbani, M. Golam; Verma, Amit; Nekovei, Reza; Khader, Mahmoud M; Anantram, M.P. ( IEEE , 2014 , Conference Paper)We model single silicon nanowire (SiNW) solar cells with dissimilar work function metal contacts. Both short circuit current (ISC) and open circuit voltage (VOC) have been investigated. Effects of nanowire dimension, ... -
