CESI on Gigawatt

CESI was featured on LA7’s program Gigawatt – Tutto è energia, offering viewers an inside look at the research and technological innovation behind its space solar cells.

During the episode, hosted by Marco Gisotti, the spotlight was on CESI’s laboratories, where advanced solutions are being developed to enhance the performance and sustainability of satellite applications. Research activities are currently focused on two main objectives: increasing solar cell conversion efficiency and reducing production costs.

To improve efficiency, CESI is studying highly innovative metamorphic materials whose underlying physical mechanisms are still being explored. This challenge has led to the development of advanced mathematical models created directly within the company’s laboratories, reinforcing CESI’s role not only as a manufacturer but also as a research-driven organization.

At the same time, significant progress has been achieved in reducing production costs through innovation in the protective cover glass used in space applications. This component is essential to shield solar cells from protons and micrometeorites. CESI has developed an alternative material, deposited in-house, capable of providing the same level of protection at lower cost while adapting to different cell shapes.

Today, more than 100 satellites equipped with CESI-produced solar cells are already in orbit. These satellites support essential daily services including communications, satellite navigation and weather forecasting. Data collected from space also plays a crucial role in predicting natural disasters and coordinating civil protection interventions, demonstrating how space technologies generate tangible benefits on Earth.

Through continuous investment in advanced materials and technological innovation, CESI confirms its position as a center of excellence in the research and production of high-performance solar solutions for space, contributing to safer and more sustainable satellite applications for the future.
