Novel flexible solar cell coverglass for space photovoltaic devices

A flexible space solar cell coverglass replacement called Pseudomorphic Glass (PMG) has been under investigation in hopes of providing a robust, high transmissivity replacement for conventional coverglass. PMG is composed of ceria doped borosilicate or fused silica beads incorporated in a variety of polymer matrices. The glass beads provide the primary radiation protection and the polymer matrix provides the mechanical integrity. PMG development has recently focused on optimization of optical performance (transmissivity and scattering), bead material and development of optical coatings.
