It is found that doping can improve the photoluminescence quantum yield by making radiative recombination faster. This effect can benefit, or harm, photovoltaic performance given that the improvement of photoluminescence quantum efficiency and open-circuit voltage is accompanied by a reduction of the diffusion length.
The photovoltaic performance may improve at an optimum doping density which depends on a range of factors such as the mobilities of the different layers and the ratio of the charge carrier capture cross sections.
In a new study, NIST scientists have conducted a comprehensive analysis on the impact of doping photovoltaic perovskites. The researchers found that for the perovskite solar cells they studied, a 5% concentration of rubidium provided the best performance.
Inside a real device, whether doping will improve photovoltaic performance will depend on the interplay of the two effects of doping listed above. Besides, other factors like mobility of the transport layer, the asymmetric coefficients of recombination will also influence the impact of doping on photovoltaic performance.
So, from our analysis so far it appears that a higher doping concentration makes the recombination mechanism radiatively limited and hence might improve the open-circuit voltage of a solar cell made from such a material.

In addition, the hall measurement results confirmed that the 10 17 cm −3 doping concentration Si wafer has a low resistivity and highest carriers mobility and suspected the influence basic electrical properties caused by the concentration. The decrease of carrier mobility of N18 also explained the PCE reduction for N18.
