A novel technique for improving the efficiency of a photovoltaic solar cell based on the band-trap impact ionization phenomenon

Abstract

In this paper, we consider a photovoltaic silicon solar cell in which the charge carriers are field E o to be avoided has been carried out. The interest of the obtained results is firstly economical since it could be useful in avoiding strong and undesirable external applied electric field on solar cells. The second interest is that they permit to identify the approximate maximum efficiency value of solar cell band-trap impact ionization.

NEW EXACT SOLUTIONS FOR A SEMICONDUCTOR NONLINEAR REACTION-DIFFUSION EQUATION: THE COMBINATION OF THE FACTORIZATION METHOD TO THE PROJECTIVE RICCATI EQUATION METHOD Vol. 5(2) July 2017, No. 27, pp. 271-288 MIBAILE JUSTIN, GASISSOU MARCEL, GAMBO BETCHEWE, SERGE Y. DOKA AND KOFANE TIMOLEON CREPIN

“…These solutions may find their applications in many domains where semiconductor devices are used: in nonlinear electronics for the introduction of new switching devices. Moreover, solitary carriers transport in semiconductors could be used to reduce losses in solar cells like in [22]. In addition the solitary form of the electric field (fig( 2)) could be helpful for developing lossless wireless data transport devices needed in telecommunication.…”
