Thin film photovoltaic cells and strings of cells may be electrically joined in series. More specifically, electrical contacts between photovoltaic cells may be formed by positioning the cells between a pair of interconnection substrates, each of which includes a conductive grid. By positioning the cells appropriately between the substrates, an electrical connection is formed between one polarity of a given cell and the opposite polarity of an adjacent cell.

Photovoltaic modules may include multiple flexible thin film photovoltaic cells electrically connected in series, and laminated to a substantially transparent top sheet having a conductive grid pattern facing the cells. Methods of manufacturing photovoltaic modules including integrated multi-cell interconnections are provided. Methods may include steps of coordinating, integrating, and registering multiple rolls of substrates in continuous processes.


Patent
Global Solar Energy | Date: 2013-12-16

Improved methods and apparatus for forming thin-film layers of chalcogenide on a substrate web. Solutions containing the reactants for the chalcogenide layer may be contained substantially to the front surface of the web, controlling the boundaries of the reaction and avoiding undesired deposition of chalcogenide upon the back side of the web.

Patent

Thin film PV cells and strings of such cells that may be electrically joined with conductive tabs or ribbons. A semi-flexible, electrically conductive adhesive is applied to join the tabs to the front and back of a cell, providing a conductive pathway between the tab and solar cell, with good adhesion to both. The tabs may be constructed of one or more materials having a thermal expansion coefficient that closely matches that of the substrate material of the cells, so that when the string or module is subsequently heated, mechanical stress between the tab and solar cell is minimized. The semi-flexible nature of the ECA also acts to relieve stress between the tab and the solar cell, decreasing the possibility of adhesion failure at critical locations. One or more dielectric materials may be applied to the PV cells and/or the tabs in regions where a tab crosses the edge of a cell, to avoid electrical shorting between the negative and positive electrodes of the cell.

A method of manufacturing solar cell includes providing a semiconductor substrate. A coating layer is then formed on a plurality of sides. Subsequently, an anti-reflective layer is formed on the layer. Finally at least one first electrode and at least one second electrode are formed. The first and second electrodes respectively and electrically connect to the second conductive amorphous substrate and the semiconductor substrate. The potential induced degradation is greatly reduced.


Patent
Global Solar Energy | Date: 2016-06-27

Improved methods and apparatus for forming thin-film buffer layers of chalcogenide on a substrate web. Solutions containing the reactants for the buffer layer or layers may be dispensed separately to the substrate web, rather than being mixed prior to their application. The web and/or the dispensed solutions may be heated by a plurality of heating elements.


Improved methods and apparatus for forming thin-film layers of semiconductor material absorber layers on a substrate web. According to the present teachings, a semiconductor layer may be formed in a multi-zone process whereby various layers are deposited sequentially onto a moving substrate web. At least one layer is deposited from a mixed gallium indium source.
