CPV Module to Rate Antireflective and Encapsulant Coating in Outdoor Conditions
Résumé
Reflections are the most important channel losses in CPV modules. Since high efficiency solar cells need a protection against moisture and oxidation, we study an antireflective coating which also encapsulates the solar cells. It is based on a monolayer of microbeads partially submerged into PDMS. In this work, a CPV module is designed to compare the electrical performance of encapsulated and bare solar cells. A preliminary study demonstrates an increase in short-circuit current by 3.8% with EQE measurements and simulations. Outdoor measurements in Sherbrooke, Quebec, Canada gave a 6.4% increase in current for a 280X module on a clear cold day in September, after rejecting aberrant measurements, which confirms the interest of using microbeads as an antireflective coating for CPV applications.
