A flexible solar cell assembly having solar cells that are positioned within a sealed module chamber. A sealed wiring chamber is positioned on an end of the sealed module chamber and is interposed between the sealed module chamber and a junction box. Wiring interconnecting the junction box to the solar cells in the sealed module chamber is routed through the sealed wiring chamber to inhibit water entry into the sealed module chamber via the wiring.

摘要:
An apparatus for and a method of interconnecting at least two solar cells using contact areas which are formed on the conductive substrates of the solar cells is described. The contact areas are formed by a material removal process which removes high resistance surface layers of the conductive substrates at the contact areas. A stringing process serially interconnects the solar cells by connecting each contact area that is cleared of high resistance surface layer to the terminal of one of the adjacent solar cells.

The present invention provides module structures and methods of manufacturing rigid or flexible photovoltaic modules employing thin film solar cells fabricated on flexible substrates, preferably on flexible metallic foil substrates. The solar cells may be Group IBIIIAVIA compound solar cells or amorphous silicon solar cells fabricated on thin stainless steel or aluminum alloy foils. In one embodiment, initially a solar cell string including two or more solar cells is formed by interconnecting the solar cells with conductive leads or ribbons. At least one bypass diode electrically connects conductive back surfaces of at least two solar cells. The bypass diode and the solar cells are encapsulated with support material and are packed with the protective shell such that the at least one bypass diode is placed between at least one solar cell and the bottom protective sheet. The bypass diode is thermally connected to the back conductive surface of one of the solar cells so that the back conductive surface of the solar cell functions as a heat sink.

A method for encapsulating interconnected solar cells including Group IBIIIAVIA absorbers and an apparatus according to the same, whereby a light receiving side encapsulant layer including thermoplastic polyurethane is used to cover the light receiving sides of the interconnected solar cells. The back sides of the interconnected solar cells are covered with a back side encapsulant layer that is different from the light receiving side encapsulant layer.
摘要:
A plurality of solar cells is connected together in a shingled fashion. Each of the solar cells includes grid wires that are attached to an electrode of the solar cell so as to receive charge carriers produced when photons are absorbed by the solar cell. The grid wires are then interconnected with adjacent solar cells when the solar cells are shingled together. The grid wires may be applied to the solar cells via a laminate and the electrical interconnection of the grid wires may be achieved by the use of a conductive epoxy.

Embodiments of the present inventions provide structures and methods for manufacturing high electrical conductivity grid patterns having minimum shadowing effect on the illuminated side of the solar cells. To manufacture a conductive grid for a solar cell, a first conductive layer is initially formed over a transparent conductive oxide layer of a solar cell. The first conductive layer has a pattern including a busbar and fingers connected to the busbar. Next, a second conductive layer is formed on the first conductive layer. In one embodiment, the first conductive layer includes silver and the second conductive layer includes carbon nano tube material, or the first conductive layer includes carbon nano tube material and the second conductive layer includes silver.
