Abstract
If photovoltaic modules are to be produced in the developing countries, e.g. Egypt, the need arises to reduce the cost in order to become economically attractive as practical devices for large scale production of electricity. Part of the cost reduction must be achieved by manipulating the encapsulation materials. As many of the encapsulation materials are polymeric, cost reduction necessitate the use of an alternative cheap polymer which is locally available.
It was meant to introduce the subject by giving a detailed account of the materials and processes used in photovoltaic nodules production. Also, the theories and methods of testing of the polymer were discussed in details to enable various workers to tackle this subject of research.
This work discusses the possibility of using the less xpensive, easily available polyurethane (PU) as a pottant
terial as well as polydiene rubber for a back cover of the photovoltaic modules.
The candidate material has to pass several tests and
certain standards before it can be considered as pottant adhesive.
