The use of ultra-wide bandgap transparent conducting beta gallium oxide (β-GaO) thin films as electrodes in ferroelectric solar cells is reported. In a new material structure for energy applications, we report a solar cell structure (a light absorber sandwiched in between two electrodes - one of them - transparent) which is not constrained by the Shockley-Queisser limit for open-circuit voltage (V) under typical indoor light.
