Abstract

The current study reports the performance degradation of the short-circuit current density, open-circuit voltage, fill factor, and conversion efficiency of organic solar cells made of poly(3-hexylthiophene) and [6,6]-phenyl C61 butyric acid methyl ester. These parameters, which are functions of time, were measured as functions of perdurability at low room temperature (below 10 °C). The short-circuit current density and open-circuit voltage were found to decrease along an approximate exponential decay as a function of total time. The fill factor of the cells increased in a zigzag manner. The result of the conversion efficiency showed a rapid index decrease..
