EFFECT OF CRYSTAL SIZE ON THE OPTIMUM TEMPERATURE FOR THE HIGHEST CAPACITY OF A TREE-DIMENSIONAL POLYCRYSTALLINE SILICON SOLAR CELL

In this work, we have proposed a method for determining the optimum temperature of an n+-p-p+ single-face silicon photocell under polychromatic front illumination using Fossums temperature-dependent diffusion coefficient model Dn (T). The capacitance is therefore determined as a function of temperature and the x and y dimensions of the crystal. The optimum temperature Topt that gives the best short-circuit capacitance is determined from the profile of the logarithm of capacitance versus the logarithm of temperature for different grain sizes.
