NOVELTY - The module (100) has multiple interconnected photovoltaic cells (102) which are arranged between a light transmissive front layer (104) and a back layer (106). A light transmissive encapsulant (110) is arranged between multiple copper indium gallium selenide photovoltaic cells and the back layer. A fibrous reinforcement is arranged within one of and/or between the back layer and the thermoplastic polymer encapsulant. The fibrous reinforcement consists of woven and non-woven fibers that are oriented in the axis of one of the orthogonal length and width dimensions of the module.    USE - Frameless photovoltaic module.    ADVANTAGE - Since the rigid back layer is replaced with lighter weight flexible material, the cost of handling and the module weight can be reduced. The exterior weatherable back layer provides resistant to moisture, ultra violet (UV) exposure and temperate climate temperature variations. The module retains the required load rating by incorporation of oriented fibrous reinforcement in the back side encapsulant, in the back layer, or separate sheet between the encapsulant and the back layer so that the overall stiffness and the strength of the module can be increased. The front and back layers provide the environmental protection and mechanical support required for reliable module operation. As the edge material has low inherent water vapor transmission rate (WVTR), moisture can be absorbed and the incursion can be prevented. Since the siloxane is incorporated into the thermoplastic polymer encapsulant, the adhesion can be promoted to glass fibrous reinforcement. The glass fibrous reinforcement is silynized to enhance bonding to thermoplastic polymer encapsulant.
