| 发明名称 | Multilayer thin-film back contact system for flexible photovoltaic devices on polymer substrates | ||
| 摘要 | 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 formed at the back side of the polymer substrate. A metal structure is formed at the device side of the polymer substrate. | ||
