Contribution to the optical design of a concentrator with uniform flux for photovoltaic panels

---

Résumé

In this investigation the aim is to broaden the space of optics for Low Concentrating Photovoltaic applications. The main target is to achieve the concentration of sunlight uniformly over a large photovoltaic receiver. To solve this problem we implemented a Monte-Carlo method and defined a new parameter in order to facilitate the analysis of irradiance distributions. The geometric parameters to consider in order to reach the optimization goals have been established by dichotomous search. Utilizing this numeric
method, we analyzed the influence of several geometrical parameters on the behavior of hypothetical optics. With this procedure we obtained a probative configuration made of simple geometries, leading to an uniform irradiation distribution.
