Maximum power efficiencies of 10.12%, 8.17% and 7.72% were achieved by matching glass reflectance  to the wavelength that the specific cell is designed to most optimally transmit.
Optimal power efficiencies of 10.12%, 8.17%, and 7.72% were achieved by aligning glass reflectance with the wavelengths that correspond to the most effective transmission for each specific cell design.
