Multilayer Thin-Film Back Contact System For Flexible Photovoltaic Devices On Polymer Substrates
- Thornton CO, US Richard Thomas Treglio - Thornton CO, US Joseph H. Armstrong - Littleton CO, US
International Classification:
H01L 31/02 H01L 31/046 H01L 31/032
Abstract:
A photovoltaic element includes a polymer substrate having opposing device and back sides, and having a coefficient of thermal expansion of at least 4 parts per million per degree Celsius but not exceeding 12 parts per million per degree Celsius. A metal structure is disposed on the device side of the polymer substrate, and the metal structure includes (a) a transition-metal-based layer disposed on the polymer substrate, (b) an aluminum-based barrier layer disposed on the transition-metal-based layer, and (c) a molybdenum-based cap layer disposed on the aluminum-based barrier layer. A CIGS photovoltaic structure is disposed on the molybdenum-based cap layer.
Multilayer Thin-Film Back Contact System For Flexible Photovoltaic Devices On Polymer Substrates
A polymer substrate and back contact structure for a photovoltaic element, and a photovoltaic element include a CIGS photovoltaic structure, a polymer substrate having a device side at which the photovoltaic element can be located and a back side opposite the device side. A layer of dielectric is optionally formed at the back side of the polymer substrate. A metal structure is formed at the device side of the polymer substrate.
