The silicate phosphor on the surface of GaAs solar cell are demonstrated to have promising potential for efficient solar spectrum utilization. The phosphor is a common utilized material in white light LED package, so the cost of phosphor is relatively low and the stability is good. The solar cells showed an enhancement of 22.8% in short-circuit current density and approximately 25.3% in power conversion...
This work demonstrates hybrid InGaN/GaN multiple quantum well (MQW) solar cells with enhanced power conversion efficiency using colloidal CdS quantum dots (QDs) and back-side distributed Bragg reflectors (DBRs). CdS QDs can absorb ultraviolet (UV) photons, which are strongly absorbed by indium tin oxide (ITO), and they emit photons with a longer wavelength. This process improves the collection of...
