Temperature Dependence of Carrier Mobility in SubPc and C_(60) Organic Semiconductors for Photovoltaic Applications

摘要

Carrier mobility is an important parameter in determining device performance in optoelectronics. Here, we study the charge carrier mobility of C_(60) and SubPc neat layers for different temperatures calculated in darkness. The results show that temperature affects the disorder energy (σ) of organic semiconductors; when the temperature is <289 K, this parameter is around 0.03 eV and it is double when the temperature is >289 K. In these conditions, the mobility of electrons and holes are around 0.14 and 10~(-7) Cm~2/Vs, respectively. Our results are in good agreement with experimental data reported by Pandey et al., Adv Funct Mater 22:617-624. 2012)
