The temperature dependence of individual efficiencies (Absorption efficiency, Thermalization efficiency, Thermodynamic efficiency and Fill factor) and overall conversion efficiency of a polycrystalline silicon solar cell has been investigated in temperature range 10–50 °C. The all efficiencies present a decrease versus temperature increase.
The base doping level on which the open circuit voltage depends can be used to improve the temperature resistivity of the polycrystalline silicon PV cell. A comparison was made between the overall efficiency obtained by the conventional method and the overall efficiency found by the multiplication of the four individual efficiencies.
Individual efficiencies for different temperatures. η thermo (T) and FF (T) are then the means factors causing the degradation of the output performances of the polycrystalline silicon solar PV cell.

Polycrystalline silicon PV cell structure. It will be assumed the ideal solar cell in this study. The contribution from the base to the photocurrent being greater than that of the emitter (Furlan and Amon, 1985). The present work will be taken account the base contribution assumed the center of the generation-recombination phenomena.
The intrinsic carrier’s density decreases strongly with the temperature increase. Some studies have shown that the polycrystalline PV cell supports the temperature increase more than the monocrystalline PV cell.
Despite the significant lifespan reduction attributed to the volume expansion of the active material, SE disintegration, and the formation of voids, which inherently leads to a decrease in capacity, the polycrystalline particles demonstrated superior retention due to the penetration of SE into the interior of the primary particles.
