Résumé

From few millimeters to few hundreds of micrometers, solar cells used in CPV systems are made smaller and smaller, to benefit from the lower influence of the temperature and series resistance. We propose in this work microconcentration systems adapted to thin film microcells arrays. Due to the miniaturization, the complete system is expected to be very compact, lightweight, enabling a simple tracking. First, a numerical study has been performed to evaluate an optimal design with only plano-spherical microlenses with a geometrical ratio of 100x and an acceptance angle around +/-3°. Second, a fabrication process has been developed to realize the designed system. Arrays of 2500 microlenses with a diameter between 300 and 500µm and a focal length around 1mm have been created. Finally, we propose a first prototype coupling 2500 microcells and microlenses arrays for middle concentration applications.
