This project aims to develop a new method to keep solar collectors dirt- and dust-free and thereby maintain high optical efficiency. This project will develop large-scale prototypes, cost-effective manufacturing processes, and commercialization of the technology in large-scale CSP devices for their applications in semi-arid and desert climates.

Objectives 
  • Establishing proof-of-concept of the application of the electrodynamic screen (EDS) for self-cleaning solar concentrators
  • Producing and evaluating laboratory-scale prototypes of self-cleaning solar collectors, including flat mirrors and curved mirrors
  • Testing the EDS-incorporated collectors for their optical efficiency of sunlight, dust-removal efficiency, power requirements, and durability.
