SOLAR MODULE HAVING TRANSPARENT POLYURETHANE FRONT AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To develop a photovoltaic module which can be manufactured by a speedy and simple method superior in efficiency in terms of cost. SOLUTION: Transparent polyurethane 1 is used as the front of a solar module. Since polyurethane as the advantage of high stability inexpensive material cost and low density in an atmospheric condition, speedy workability at the low temperature of 100 deg.C is supplied. It is desirable that a solar cell 3 is completely buried in transparent polyurethane 1. Transparent polyurethane 1 is used in the front and the material like non-transparent polyurethane 2 and the like is used in a back.
