ABSTRACT: Heating a
solar cell subjected to incident solar irradiance is studied. Laplace Integral
Transform technique is applied to get the temperature field within the cell. The
efficiency as a function of the cell temperature is estimated, and its
variation with the local day time is thus clarified. Different cooling levels
are considered. An illustrative example is given. The results show that the diurnal
temperature variation of the cell is significant, while the efficiency is
revealed to be a slowly varying function of temperature along the day time. It
is revealed that as the temperature of the cell increases the efficiency
decreases. Thus shading and cooling conditions may be useful to increase its
efficiency.
