NOVELTY - A solar cell module (100) comprises solar cell device (102) including at least two solar cells (108), each solar cell including Group IBIIIAVIA absorber layer and conductive substrate; light receiving side encapsulant layer (104) coating light receiving surface, where light receiving side encapsulant comprises thermoplastic polyurethane; and back side encapsulant layer (106) coating back surface, where back side encapsulant layer is different from light receiving side encapsulate layer.    USE - Solar cell module.    ADVANTAGE - Solar cell module exhibits synergistic advantage in combination with reduced packaging cost and increased module lifetime.    DETAILED DESCRIPTION - The solar cell module (100) comprises solar cell device (102) including at least two solar cells (108), each solar cell including Group IBIIIAVIA absorber layer and conductive substrate; light receiving side encapsulant layer (104) coating light receiving surface, where light receiving side encapsulant comprises thermoplastic polyurethane; and back side encapsulant layer (106) coating back surface, where back side encapsulant layer is different from light receiving side encapsulate layer. The solar cell device comprises light receiving side having light receiving surface and back side having back surface. The light receiving side of device comprises Group IIBIIIAVIA absorber layer of each solar cell and back side comprising conductive substrate of each solar cell. An INDEPENDENT CLAIM is included for a method of manufacturing the solar module comprising:    (A) providing front protective layer having a front surface and a back surface, where front protective layer is transparent;    (B) placing light receiving side encapsulant layer over the back surface of the front protective layer, where light receiving side encapsulant comprises thermoplastic polyurethane;    (C) placing solar cell device over light receiving side encapsulant layer;    (D) placing back side encapsulant layer over back surface of the solar cell device;    (E) placing back protective layer over back side encapsulant layer;    (F) subjecting multilayer structure heat and pressure to melt light receiving side encapsulant layer between front protective layer and solar light receiving side of solar cell and back side encapsulant layer between back side of solar cell and the back protective layer; and    (G) cooling multilayer structure to bond light receiving side encapsulant layer between to front protective layer and solar light receiving side of the solar cell, and back side encapsulant layer to the back side of the solar cell and the back protective layer.
