Light trapping of textured polydimethylsiloxane films for antireflection is investigated. The efficiency of GaAs solar cell with textured PDMS film reach 28% enhancement. Numerical analysis successfully rebuilds the surface profile close to the real situation.
A novel design of hybrid solar cell combining traditional GaAs-based solar cell with colloidal CdS quantum dots (QDs) is demonstrated. By applying CdS QDs on the surface of GaAs device, we can obtain an effective anti-reflection coating at long wavelength. Moreover, due to its strong absorption at ultraviolet range and efficient light emission at blue photon, CdS quantum dots can down-convert the...
