Abstract

The improved performance of hybrid solar cells was obtained due to the effects of CdSe quantum dots (QDs) blended in the active layer. Different concentrations of CdSe QDs were mixed in the poly(3-hexylthiophene):[6,6]-phenyl C₆₁ butyric acid methyl ester (P3HT:PCBM) based active layer. We investigated the effects of CdSe QDs on the solar cell performances by ranging its concentration from 2 to 24 mg/mL. The charge transport in the active layer was improved at the optimized CdSe QDs concentration of 6 mg/mL. The solar cell with pristine active layers showed a 2.98% power conversion efficiency while that with 6 mg/mL CdSe QDs blended in layer showed a higher power conversion efficiency of 3.35% under AM 1.5G illumination. Analysis of recombination mechanism using the current density-voltage (J-V) characteristic at various light intensities was also performed.
