Charge transfer in rare earth oxide hybrid solar cells.

Highlights: [•] Adding Nd2O3 to PCBM increases open circuit voltage and short circuit current. [•] Photo induced absorption decay rate increases in Nd2O3/PCBM mixture. [•] Photo induced bleaching is observed in Nd2O3/PCBM mixture. [•] Shows photo induced charge transfer occurs between PCBM and Nd2O3. [•] Provides first example of a rare earth oxide/organic hybrid solar cell. [Copyright &y& Elsevier]
