摘要:
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.
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.

A method of forming metallic connector patterns for solar cells, whereby an embosser having raised features shaped in the form of a metallic connector pattern is used to attach a portion of a metallic foil to a transparent conductive layer formed on a top transparent surface of a solar cell structure. The raised surfaces of the embosser press the metallic foil portion against the transparent conductive layer. Heat and pressure directed to the metallic foil portion attach the metallic foil portion to the underlying transparent conductive layer, and then the rest of the metallic foil, which is not attached to the transparent conductive layer, is removed.

A biased pulse DC reactor for sputtering of oxide films is presented. The biased pulse DC reactor couples pulsed DC at a particular frequency to the target through a filter which filters out the effects of a bias power applied to the substrate, protecting the pulsed DC power supply. Films deposited utilizing the reactor have controllable material properties such as the index of refraction. Optical components such as waveguide amplifiers and multiplexers can be fabricated processes performed on a reactor according to the present inention.

In accordance with the present invention, a dielectric barrier layer is presented. A barrier layer according to the present invention includes a densified amorphous dielectric layer deposited on a substrate by pulsed-DC, substrate biased physical vapor deposition, wherein the densified amorphous dielectric layer is a barrier layer. A method of forming a barrier layer according to the present inventions includes providing a substrate and depositing a highly densified, amorphous, dielectric material over the substrate in a pulsed-dc, biased, wide target physical vapor deposition process.

A method of deposition of a transparent conductive film from a metallic target is presented. A method of forming a transparent conductive oxide film according to embodiments of the present invention include depositing the transparent conductive oxide film in a pulsed DC reactive ion process with substrate bias, and controlling at least one process parameter to affect at least one characteristic of the conductive oxide film.
