Enhancement of the performance of InAs quantum dots solar cell by surface modification using Poly-L-Lysine homopolymers

Abstract

The enhancement of InAs quantum dots solar cell was reported for surface modification by implementing Poly-L-Lysine (PLL) homopolymers as an anti-reflection coating. Dip coating method was used to coat the solar cell surface with PLL. The current-voltage, spectral response, and external quantum efficiency measurements were performed to characterize the solar cell. Furthermore, the transmission spectra of GaAs were obtained before and after PLL coating. At least 25% increase in the performance of the InAs quantum dots solar cell was achieved as depicted in the current voltage, external quantum efficiency, and spectral response measurements.
