Optical and thermal simulation for wide acceptance angle CPV module

Abstract

Corresponding author: nc13005@student.miyazaki-u.ac.jpAbstract. Concentrator photovoltaic (CPV) technology has the potential to decrease the cost of systems in the near future by using less expensive optical elements in the system which replace the receiving surface aperture and concentrate the sunlight onto small solar cells. One of the main concerns of CPV is the need for high precision tracking system and the relation to the acceptance angle. In this paper, we proposed a CPV module with concentration ratio larger than 100 times and wide acceptance angle. An optical simulation for the module with S-TIM2 glass as a lens material was conducted to estimate the optical performance of the module. Thermal and electrical simulation was also conducted using COMSOL Multiphysics and SPICE respectively to evaluate the working temperature and electrical characteristics of the multijunction solar cell under concentration conditions.

“…Concentrating photovoltaic (CPV) systems could play an important role as it has the potential to reduce the size of solar cells needed by operating them more efficiently. Using efficient concentrating optics to concentrate the light onto small-area solar cell is considered as one of the essentials for developing the CPVs [3,4]. These solar optics are divided into two categories according to the physical nature of how the light being concentrating by either refraction or reflection.…”
