“…To obtain an insight into the heat distribution in a cell structure and the temperature gradient in every layer, we performed the thermal simulations by coupling the thermal module to semiconductor and optic modules. Great analytical models have been presented in literature for thermodynamic behavior of physical devices [32] and solar cells (heat generation and conduction) [33]. The general heat equation is given by PDE and must be solved in steady-state is as follows for a solid body,…”
