A group led by Cambridge University has developed an adhesive-free method of bonding ultra-thin gallium arsenide solar cells to borosilicate glass. The proposed technique is reportedly compatible with ...

The cell achieved an open-circuit voltage of 1.061 V, a short-circuit current density of 29.9 mA/cm2, and a fill factor of 84.9%.

These thin-film GaAs PV cells, have one of the highest power-to-weight ratio in the industry at more than 800 watts per kilogram, noted GESemi Chief Operating Officer Kevin Shows.
