SPECTRAL RESPONSE AND EFFICIENCY OF A SILICON SOLAR-CELL BELOW WATER-SURFACE

Solar radiation below water surface is modified in that the total solar energy is decreased and the spectral width is reduced. The extent of this modification depends upon the depth in water. This change in the solar radiation reflects its effects on the performance of the light measuring devices such as solar cells, where the efficiency of these cells depends upon the spectral distribution of the incident light. For a silicon solar cell, a computational work has been performed to reconstruct the spectral response curves of the cell at various depths in water, and to calculate the efficiency at these depths relative to the cell efficiency at the water surface.
