Effects of carriers charge mobility and work function on the performances of P3HT:PCBM based organic photovoltaic solar cell

This paper reports a study on the effect of charge carriers mobility and anode work function on the performances of an organic photovoltaic cell based on polymer/fullerene P3HT: PCBM. Thus, numerical simulations have been investigated on ITO/PEDOT:PSS /P3HT: PCBM/LiF/Al structure with AMPS-1D (Analysis of Microelectronic and Photonic Structures the simulation one dimension) and GPVDM (General-Purpose Photovoltaic Device Model) softwares. The results show that the optimum efficiency is obtained for electron and hole motility values of 10⁻⁴ cm²V⁻¹s⁻¹ and 2.10⁻⁴ cm²V s⁻, respectively. Moreover, we reported that the ohmic contact for both anode and cathode electrodes of the investigated device remains very important to get the maximum efficiency. In addition, in this present work, the complimentary between the both softwares AMPS and GPVDM is also well illustrated as an original modeling approach.
