چکیده
|
Abstract: this paper presents a possible solution to improve the efficiency of photovoltaic solar cells. an external electric field is applied on a silicon photovoltaic solar cell,inducing band-trap ionization of charge carriers. output current is then monitored and the thermodynamic efficiency is calculated. results show on the one hand a significant increase in efficiency for a certain margin of applied electric field,and on the another hand the instabilities of efficiency. a simple approach is then suggested for the implementation of these results. an efficiency of 67% has been reached for an applied electric of 1586 v/cm. © 2017,the author(s).
