Hybrid polymer solar cell based on cadmium selenide quantum dots

Abstract

High quality CdSe quantum dots (QDs) were synthesized using the hot injection method. These QDs were further used for the fabrication of Hybrid polymer solar cell (HPSC) using the low band gap polymer such as P3HT. The CdSe QD sensitized polymer solar cell was fabricated using the spin coating technique. The obtained HPSC is further characterized for their optical and solar cell studies. The optical absorbance and photoluminescence of the HPSC is in the visible regime. The solar cell O/P characteristics under 1 Sun illumination produced a promising 0.6% efficiency. The corresponding current density and open circuit photovoltage values were 0.88 mA/cm2 and 278 mV respectively.
