Semiconductor encapsulant resin having an additive with a gradient concentration

A solar cell module which comprises a photovoltaic element string comprising a plurality of photovoltaic elements electrically connected with each other by means of an electric connection material, said photovoltaic element string being sealed by a sealing material, wherein when an area of one (a) of said plurality of photovoltaic elements is represented by A and a sum of clearances areas between said photovoltaic element (a) and adjacent photovoltaic elements (b) situated next to said photovoltaic element (a) is represented by B, the area ratio of B/A is in a range of 0.003 to 0.045. A process for producing a solar cell module using said photovoltaic element string by a vacuum lamination method.

Solar cell module excelling in reliability

A solar cell module has a very agreeable appearance and can carry a large volume of information on the light receiving surface thereof. An information carrying body storing information (including, for example, the date, the process the rated values, the destination of shipment, I-V curve data and other data) for identifying the module is invisibly arranged on the light receiving surface side of the solar cell module (e.g., on the front surface sealing member or the front surface member of the photovoltaic elements).

Solar cell module and method of manufacturing the same

For providing a solar cell module that has the structure with high reliability without peeling off of an adhesive and an encapsulating material from a reinforcing plate even in long-term outdoor exposure and that can be produced at low cost by reduction of material cost, the reinforcing member for solar cell module has organic resin layers on the both surfaces thereof and a thickness of the organic resin layer on one surface side is smaller than that of the organic resin layer on the other surface side.

Solar cell module and reinforcing member for solar cell module

The solar cell module of the present invention comprises a solar cell device sealed with a sealing material between a support member and a protective film, wherein at least one of the protective film and the sealing material covers the edge of the support member. The above structure can prevent the sealing material from peeling from the edge of the solar cell module. Also, it can prevent rust from occurring at the edge when the support member is a steel sheet. Further, it can prevent the peeling by a simpler step than in the case of use of the conventional protective member for prevention of peeling.
