The idea of light deflection was proposed to improve the efficiency of bifacial photovoltaic modules, where unused light is redirected to solar cells for additional current generation. However, the measured results fell short of the simulated expected gain of up to 11%, achieving only about 3%.
To improve the efficiency of bifacial photovoltaic modules, the idea of light deflection was addressed. A thin film with an intended structure was applied in the space between the cells. Due to the selected structural geometry, unused light is specifically redirected to the solar cell and can be absorbed by it and converted into additional current. The effect of the light-directing film was both simulated and measured. Single PV modules without and with commercial structured films or white back sheet were measured to evaluate the results The expected gain of up to 11% from the simulation could not be achieved by measurement, by reaching about 3%.
