[0201] component formation

[0202] Two assemblies (assemblies A and B) were formed according to the method of the invention. In addition, four comparison assemblies (comparison assemblies A-D) not according to the method of the present invention were also formed. In modules A and B, a plurality of fibers extend laterally through the second layer to the outer edge of the module on both ends of the module.

[0203] More precisely, component A includes:

[0204]A first outermost layer (glass) of 156mmx156mmx3.2mm having a light transmittance of at least 70% as determined using the UV / Vis spectrophotometric method of ASTM E424-71;

[0205] A 156mmx156mmx200μm photovoltaic cell on the first outermost layer;

[0206] A is not uniformly distributed over and through the photovoltaic cell and includes a 5-mil second 5-mil second as a fabric (non-woven glass cloth) of a plurality of fibers at least partially coated with the first liquid silicone composition. layers; and

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.

Description

technical field [0001] The present invention generally relates to photovoltaic cell modules and photovoltaic cell arrays. More precisely, the present invention relates to a photovoltaic cell assembly comprising a first outermost layer, a photovoltaic cell and a second outermost layer, which have specific characteristics and are placed on the photovoltaic cell to clamp the photovoltaic cell Between the second outermost layer and the first outermost layer. The invention also relates to methods of forming photovoltaic cell assemblies. Background technique [0002] A photovoltaic cell (photovoltaic cell) is a semiconductor device used to convert light into electricity. There are two main types of photovoltaic cells, silicon wafer and thin film. A silicon wafer is a thin sheet of semiconductor material that is typically formed by mechanically cutting a silicon wafer from a single crystal or polycrystalline ingot. Alternatively, silicon wafers can be formed by casting. Thin f...
