Abstract:
The present disclosure relates to photovoltaic ("PV") solar cell comprising a frontside busbar tape in electrical contact with narrow front busbars (e.g., silver busbars). A single frontside busbar tape may be in electrical contact with a single narrow front busbar or with a dual set of narrow front busbars. The disclosure also relates to modified gridlines and methods of enhancing the electrical connection between gridlines and narrow busbars and busbar tape on a solar PV cell.
Abstract:
Die vorliegende Erfindung betrifft ein Verbundsystem zur Rückseitenkontaktierung von Photovoltaik-Modulen, bestehend aus einer Metallfolie, die eine Leiterbahnstruktur aufweist und mindestens einer elektrisch isolierenden und stabilisierende Polymerschicht, die auf der Metallfolie aufgebracht und haftend mit dieser verbunden ist. Die Hauptaufgabe der stabilisierenden Polymerschicht besteht darin die strukturierten Leiterbahnen mechanisch zu stabilisieren, so dass sich diese beim Auftreten von Scherkräften, ausgelöst beispielsweise durch erhöhte Temperatur während des Laminationsvorgangs oder im Betrieb, nicht verschieben.
Abstract:
A method for encapsulating photovoltaic cells into single functional units is described. These units share the mechanical and electric properties of the encapsulation layers and allow for flexible module architecture to be implemented at the cell level. This enables cost reduction and improved performance of photovoltaic power generation.

Abstract:
Methods are provided for electrically contacting a photovoltaic cell and for electrically interconnecting such cells. The methods comprise providing a woven fabric comprising a plurality of electrically conductive wires being provided in a single one of a warp direction and a weft direction, the woven fabric further comprising a plurality of polymer yarns being provided in at least the other one of the warp direction and the weft direction. The woven fabric is brought into physical contact with a surface of a photovoltaic cell comprising a plurality of metal contacts, and afterwards a heating step is performed, thereby establishing an electrical connection between the respective metal contacts and at least one electrically conductive wire and thereby liquefying the plurality of polymer yarns and transforming them into an encapsulation layer.
Abstract:
One embodiment of the present invention provides a bifacial solar panel. The bifacial solar panel includes a first transparent cover on a first side of the solar panel, a second transparent cover on a second side of the solar panel, a plurality of solar cells sandwiched between the first cover and the second cover, and one or more lead wires for outputting power generated by the solar panel. The lead wires are positioned on an edge of the solar panel without shading the first and second sides of the solar panel. A respective solar cell comprises a photovoltaic structure, a first metal grid on the first side of the photovoltaic structure, which allows the solar cell to absorb light from the first side, and a second metal grid on the second side of the photovoltaic structure, which allows the solar cell to absorb light from the second side.
