In the paper “GaAs solar cells grown on acoustically spalled GaAs substrates with 27% efficiency,” which was recently published in Joule, the researchers explained that the acoustic spalling ...

solar cells that allow the recovery of germanium films. The new cell achieved an efficiency that is reportedly in line with that of other GaAs PV devices, but can be produced at a lower cost ...

Results displayed that GaSb/GaAs quantum dots improved the solar cell performance, with a 36.3% increase in the solar cell efficiency. Additionally, the application of indium arsenide/gallium ...

Take a 20% efficient solar cell for example, sized at one square ... include indium gallium phosphide (InGaP), gallium arsenide (GaAs), germanium (Ge), and indium gallium arsenide (InGaAs).

can be disregarded with this technique. 【Fig. 4】Smart stack technology A GaAs/InP-based four-junction solar cell has achieved conversion efficiency as high as 31.6%, and a GaAs/CIGS-based ...
