COMSOL Simulation of Heat Distribution in InGaN Solar Cells: Coupled Optical-Electrical-Thermal 3-D Analysis

Résumé

Thermal distribution in solar cells has been rarely investigated despite it significant impact on the performance. Moreover, despite the fact that the achievements of InGaN solar cells are still mostly at the state of laboratory studies, the presented work is devoted to present original results on coupled phenomena occurring in the cells that makes it possible to highlight new possible guidelines for an improve of their efficiency. To our knowledge, most of the modeling results of thermal dissipation in InGaN-based solar cells published in the literature are based only on the 1-D model, not or little on the 3-D model. Thus, results presented in the current contribution are obtained by a COMSOL Multiphysics 3-D analysis of the electrical and optical photogeneration properties in relation with the heat distribution in InGaN solar cell. For this simulation, we have coupled the "Semiconductor Module", the "Heat Transfer Module for Solids," and the "Wave Optics Module" allowing us to calculate the Shockley-Read-Hall heating, the total heat flux, the Joule heating the carrier's concentration, the electric field, and the temperature dissipation in the InGaN solar cell structure. This approach allows the optimization of the device stability by determining the heating sources responsible of performance drop over time. Finally, the original results of these simulations show the great possibilities offered by InGaN-based solar cells with regard to their potential to dissipate the temperature and, more generally, their application interests related to their good thermodynamic behavior.
