The aging effect on P3HT:PCBM organic solar cells was
investigated with camphorsulfonic doped polyaniline (PANI:CSA) or poly(3,4-
ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) used as the
hole transport layer (HTL). The cells were encapsulated and exposed to a
continuous normal atmosphere on a dark shelf and then characterized
intermittently for more than two years. The photovoltaic results revealed that
the cells with PEDOT:PSS HTL showed better initial results than the cells with
PANI:CSA HTL. Over time, PEDOT:PSS-based cells exhibited faster
degradation than PANI:CSA-based cells, where the average efficiency of six
cells dropped to zero in less than one and a half years. On the other hand,
PANI:CSA-based cells exhibited a much more stable performance with an
average efficiency drop of only 15% of their initial values after one and a half
years and 63% after two years. A single-diode model was utilized to fit the
experimental data with the theoretical curve to extract the diode parameters,
such as the ideality factor, to explain the effect of aging on the diode’s performance.
