使用simplen+ p-同质结阐明了有机光伏电池中ppm级浓度掺杂的影响。随着掺杂从0到10 ppm，填充因子增加，由于多数载流子的出现。从10到100 ppm，由于内建电势的增加，光电流密度增加，即，ann+ p-同质结的形成。通过用浓度为100 ppm的受体分子直接掺杂光活性共沉积层，光电流增加了1.3倍。
The effects of doping at concentrations at the ppm level in organic photovoltaic cells were clarified using simplen+p-homojunctions. With doping from 0 to 10 ppm, the fill factor increased due to the appearance of majority carriers. From 10 to 100 ppm, the photocurrent density increased due to an increase in the built-in potential, i.e., the formation of ann+p-homojunction. The photocurrent was increased by a factor of 1.3 by directly doping the photoactive co-deposited layer with acceptor molecules at a concentration of 100 ppm.
