Photovoltaic Cell Module And Method Of Forming
First Claim
1. A photovoltaic cell module comprising:
- A. a first outermost layer having a light transmittance of at least 70 percent as determined by UV/Vis spectrophotometry using ASTM E424-71;
B. a photovoltaic cell disposed on said first outermost layer; and
C. a second outermost layer opposite said first outermost layer, said second outermost layer comprising a plurality of fibers at least partially coated with a silicone composition and disposed on said photovoltaic cell sandwiching said photovoltaic cell between said second outermost layer and said first outermost layer,wherein said silicone composition is further defined as hydrosilylation-curable and comprises;
(i) an organosilicon compound having at least one unsaturated moiety per molecule,(ii) an organohydrogensilicon compound having at least one silicon-bonded hydrogen atom per molecule, and(iii) a hydrosilylation catalyst used to accelerate a hydrosilylation reaction between (i) said organosilicon compound and (ii) said organohydrogensilicon compound,wherein a ratio of silicon-bonded hydrogen atoms per molecule of (ii) said organohydrogensilicon compound to unsaturated moieties per molecule of (i) said organosilicon compound is from 0.05 to 100.

Abstract
A photovoltaic cell module, a photovoltaic array including at least two modules, and a method of forming the module are provided. The module includes a first outermost layer and a photovoltaic cell disposed on the first outermost layer. The module also includes a second outermost layer disposed on the photovoltaic cell and sandwiching the photovoltaic cell between the second outermost layer and the first outermost layer. The method of forming the module includes the steps of disposing the photovoltaic cell on the first outermost layer, disposing a silicone composition on the photovoltaic cell, and compressing the first outermost layer, the photovoltaic cell, and the second layer to form the photovoltaic cell module.

12. A method of forming a photovoltaic cell module comprising a first outermost layer having a light transmittance of at least 70 percent as determined by UV/Vis spectrophotometry using ASTM E424-71, a photovoltaic cell disposed on the first outermost layer, and a second layer disposed on the photovoltaic cell sandwiching the photovoltaic cell between the second layer and the first outermost layer and comprising a plurality of fibers at least partially coated with a liquid silicone composition having a viscosity of less than about 100,000 cps at 25°
- C., said method comprising the steps of;
A. disposing the photovoltaic cell on the first outermost layer; B. disposing the liquid silicone composition on the photovoltaic cell; and C. at least partially coating the plurality of fibers with the liquid silicone composition to form the second layer; and D. compressing the first outermost layer, the photovoltaic cell, and the second layer to form the photovoltaic cell module, wherein the plurality of fibers extends laterally across the second layer to a periphery of the photovoltaic cell module on both ends of the module to resist leakage of the liquid silicone composition from the photovoltaic cell module during the step of compressing. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
