摘要

Ternary systems based on mixtures of polymer, PCBM and CdSe nanoparticles were investigated. The photophysical and electrochemical properties were modulated by changing the size of the inorganic nanoparticles and their effects on the performance of the solar cells were analyzed. At the optimized conditions, the presence of the nanoparticles increased the photocurrent and photovoltage, improving the efficiency of the devices. A complete study on the morphologic effects induced by the presence of these nanoparticles was performed using AFM, HR-TEM and optical microscopy techniques.
