FIG. 1.

Carrier concentration vs delay time of a pristine (bottom) and annealed (top) P3HT:PCBM solar cell for different temperatures. The pristine sample shows a strong temperature dependence typical for bimolecular Langevin-type recombination. In contrast, the annealed sample shows only a very weak temperature dependence. At long delay times and high temperatures, artefacts due to injection can be observed by the inflexion point.

Carrier concentration vs delay time of a (a) pristine and (b) annealed P3HT:PCBM solar cell at , extracted from a photo-CELIV experiment. Numeric fits of the data using the polaron continuity equation are included, namely, the recombination types monomolecular (MR, blue dots), bimolecular with Langevin (BR, green dashed line), and reduced Langevin (black solid line) as well as third order (TR, red dashed line).

Temperature dependence of the Langevin reduction factor , the fraction of effective over Langevin recombination. Shown are the results for pristine (squares) and annealed (diamonds; the open symbols signify the determination of ignoring the parasitic injection). They are compared to values from Juska et al. (Ref. 6) (circles). The current models for the description of the reduced Langevin recombination from Koster et al. (Ref. 8) as well as Adriaenssens and Arkhipov (Ref. 7)—showing a temperature dependence not observed in the experiments—are also included.

Abstract

We determined the dominant polaron recombination loss mechanism in pristine and annealed polythiophene:fullerene blend solar cells by applying the photoinduced charge extraction by linearly increasing voltage method in dependence on temperature. In pristine samples, we find a strongly temperature-dependent bimolecular polaron recombination rate, which is reduced as compared to the Langevin theory. For the annealed sample, we observe a polaron decay rate which follows a third order of carrier concentration almost temperature independently.
