Recent developments in lightweight solar cell modules

Abstract

Two types of lightweight solar cell modules were prepared. The goal is to achieve a module with a power to weight ratio of 350 watts per kilogram. Both structures use thin cells approximately 50 micrometers thick and glass covers approximately 75 micrometers thick. In one structure the glass is bonded to the module using 93-500 silicone adhesive; while the other relies on heat and pressure bonding using FEP as the adhesive. Specific powers of about 335 watts per kilogram were achieved.
