INCREASING THE EFFICIENCY OF BIFACIAL HALF CELL SOLAR PANELS WITH REFLECTIVE BACKSIDE MATERIALS

Abstract

– It has been observed that the monocrystalline bifacial solar cell, which is now widely used, increases the power and efficiency of the designed module. Contrary to other known cell types, additional power can be obtained from the reflections obtained on the back surface and offers potentially better power outputs than standard modules. Bifacial cells are a more advanced cell type that uses absorption from albedo to increase solar gain. Bifacial cells can potentially absorb solar radiation on both surfaces of the cell to increase the amount of power and provide a higher power output than single-surface cells. In such cells, reflections from both the front and rear surfaces are captured by adding a rear electrode plate to the body. In order to use this feature of the cell efficiently, a correctly placed reflective surface design is required. In this work some different back plates are used to see the effect of reflections on the gain of bifacial solar panels.
