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...
High performance of GaAs solar cell with dual layer quantum dots separated by flexible polydimethylsiloxane film was demonstrated. By this scheme, the efficiency increased by 22 %, compared to the cell without QDs.
A colloidal quantum dot light-emitting multi-layer structure with HFO2/SiO2 distributed Bragg reflector is manufactured by pulse spray method. A pure white light with strong enhancement due to better utilization of UV pump was demonstrated.
The superior uniformity of angular-dependent CCT white LEDs have been investigated by ZrO2-type remote phosphor structure. This novel structure reduces angular-dependent CCT deviations from 1000K to 420K in range of −70 to 70 degrees.
Enhanced optical coupling with respect to all incident angles via an indium tin oxide quasi-periodic structure (ITO-QPS) for organic thin-film solar cells was demonstrated. The cell efficiency shows 13.8% enhancement after ITO-patterning.
