Improving photovoltaic performance of P3HT: IC(60)BA based organic solar cell: N-type doping effect

In this paper we report a numerical simulation study for P3HT: IC(60)BA based organic solar cell with Analysis of Microelectronic and Photonic Structures the simulation one dimension software (AMPS-1D). Indeed, the N-type doping concentration (N-D) effect on the organic solar cell performance is done. Moreover, a combination between the P-type doping concentration (N-A) and N-type one (N-D) is investigated. However, due to the relationship between doping and carriers charge mobility, the effect of N-D for different electron mobilities (mu(n)) is also studied. We showed a high efficiency of 5.88% that is achieved for particular values of N-A = 10(17) cm(-3), N-D = 2 x 10(16) cm(-3), mu(p) = 3 x 10(-4) cm(2) V-1 s(-1) and mu(n) = 7 x 10(-4) cm(2) 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: IC(70)BA is studied; an optimum efficiency of about 6.32% is reached.
