Abstract
In this paper we report a numerical simulation study for P3HT: IC60BA based organic solar cell with Analysis of Microelectronic and Photonic Structures the simulation one dimension software (AMPS-1D). Indeed, the N-type doping concentration (ND) effect on the organic solar cell performance is done. Moreover, a combination between the P-type doping concentration (NA) and N-type one (ND) is investigated. However, due to the relationship between doping and carriers charge mobility, the effect of ND for different electron mobilities (μn) is also studied. We showed a high efficiency of 5.88% that is achieved for particular values of NA = 1017 cm−3, ND = 2 × 1016 cm−3, μp = 3 × 10−4 cm2 V−1 s−1 and μn = 7 × 10−4 cm2 V−1 s−1. Thus, we noticed that the P-type doping remains more promising than N-type one for the device performance improvement. Furthermore, the validation of the obtained results by those experimentally reported in literature is realized. In addition, the doping of other BHJ OSC devices consisting of P3HT: IC70BA is studied; an optimum efficiency of about 6.32% is reached.
