NOVELTY - A photovoltaic cell module comprises: (A) a first outermost layer having a light transmittance of at least 70% as determined by UV/Vis spectrophotometry using ASTM E424-71 (2007); (B) a photovoltaic cell disposed on the first outermost layer; (C) a backsheet disposed on the photovoltaic cell; and (D) a second outermost layer opposite the first outermost layer, the second outermost layer disposed on an outward facing surface of the backsheet sandwiching the photovoltaic cell and the backsheet between the second outermost layer and the first outermost layer.    USE - The photovoltaic cell module is useful for generating electricity to power an electrical device (claimed).    ADVANTAGE - The photovoltaic cell module is highly improved and cost-efficient.    DETAILED DESCRIPTION - A photovoltaic cell module comprises: (A) a first outermost layer having a light transmittance of at least 70% as determined by UV/Vis spectrophotometry using ASTM E424-71 (2007); (B) a photovoltaic cell disposed on the first outermost layer; (C) a backsheet disposed on the photovoltaic cell; and (D) a second outermost layer opposite the first outermost layer, the second outermost layer disposed on an outward facing surface of the backsheet sandwiching the photovoltaic cell and the backsheet between the second outermost layer and the first outermost layer, where the second outermost layer is present in a coating weight of 3-75 g/m2 of the outward facing surface of the backsheet, where the backsheet and the second outermost layer each independently consist essentially of a silicone, and where the photovoltaic cell module passes the Wet Leakage Current Test at a voltage of at least 1000 Volts using IEC 61215 after humidity cycling for 1000 hours. INDEPENDENT CLAIMS are included for:    (1) a method of forming the photovoltaic cell module, which involves assembling the first outermost layer, the photovoltaic cell, the backsheet, and the second outermost layer to form the photovoltaic cell module;    (2) a bi-layer backsheet for the photovoltaic cell module, the backsheet being resistant to soiling and delamination, having a thickness, and consisting essentially of: (A) a perforated substrate; and (B) an anti-soiling layer disposed on the perforated substrate and in direct contact with perforations in the perforated substrate, where the anti-soiling layer has a thickness that is less than 10% of the thickness of the perforated substrate, where the perforated substrate consists essentially of a first silicone, where the anti-soiling layer consists essentially of a second silicone different from the first silicone and exhibits a coefficient of friction of 0.1-0.7 against itself measured according to ISO 8295, and where the anti-soiling layer is disposed on the perforated substrate at a coat weight of 3-75 g/m2 of the perforated substrate at least partially obstructing the perforations;    (3) a method of generating electricity using the photovoltaic cell module, which involves exposing the photovoltaic cell module to sunlight to generate the electricity; and    (4) a method of powering an electrical device with electricity generated by the photovoltaic cell module which involves: exposing the photovoltaic cell module to sunlight to generate the electricity; transmitting the electricity via an electrical conduit from the photovoltaic cell module to an electrical device to power the electrical device; and powering the electrical device, or an electrical component, with the electricity.
