High-efficiency c-Si based interdigitated point contact back heterojunction solar cells
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 ... -
Photoconductive response of strained silicon nanowires: A Monte Carlo study
Shiri, Daryoush; Verma, Amit; Khader, Mahmoud M. ( AIP Publishing LLC. , 2014 , Article)Using Ensemble Monte Carlo simulations, the photocurrent in a 500 nm long strained [110] silicon nanowire with diameter of 3.1 nm is investigated. It was observed that a phototransistor based on this nanowire can have ... -
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, ... -
TDDFT Studies on sheet size-dependency of optoelectronic properties of 2d silicon
Alam, MD Raiyan; Alwarappan, Ganesh; Bhandari, Aashka; Patil, Sunil; Alfalah, Sherin; Shibl, Mohamed F.; Hassan, Walid M.I.; Nekovci, Reza; Verma, Amit... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)Silicene, a two-dimensional (2D) silicon nanosheet, has gained immense interest due to potential applications, better compatibility, and expected integration with current silicon (Si) technology. This work explores the ... -
Theoretical investigation of the oxygen bond dissociation energies in graphene oxide
Hassan, Walid M.I.; Verma, Amit; Nekovei, Reza; Jeyakumar, R.; Khader, Mahmoud M. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)The theoretical vibrational spectrum, oxygen bond dissociation energies (BDE), atomic charges and hydrogen bonding has been investigated using wB97XD/6-31g(d) method of calculation. The order of BDE for C-O comes in the ...
