"high average visible transmittance of around 64%... visual appearance of TPV and TPEC is a fundamental issue... 1.47%-efficient transparent metal oxide solar cells built with n-doped zinc oxide (N:ZnO) and p-doped nickel(II) oxide (p-NiO) on a glass substrate made of indium tin oxide (ITO)... are able to generate a high photovoltage of 0.546V density of 2.28mA/cm2... “Short wavelength UV with highly-energetic photons was mostly absorbed... with an efficiency as high as 82%"
