Abstract
A photovoltaic module includes a plurality of photovoltaic devices, a first filling material formed by a resin having a first soften temperature which is disposed in an area where the photovoltaic devices are disposed, a second filling material having a second soften temperature which is disposed in an area other than the area where the photovoltaic devices are disposed, a front surface protecting material disposed on the first filling material and the second filling material. The second soften temperature is higher than the first soften temperature.
Claims12
A photovoltaic module comprising;
- a plurality of photovoltaic devices;
- a first filling material comprising a resin having a first soften temperature;
- a second filling material comprising a resin having a second soften temperature higher than the first soften temperature;
- and
- a front surface protecting material,
- wherein the first filling material is disposed at least on and in contact with front and back surfaces of the photovoltaic devices,
- the front surface protecting material is disposed on and in contact with each of the first filling material and the second filling material, and
- one or more sides of a photovoltaic device of said plurality maintains contact with the second filling material, wherein the second filling material does not exist above and below the photovoltaic cell.
