TEL Solar is a manufacturer of production equipment for the manufacturing of thin-film silicon solar modules.TEL Solar owns the patent for the double junction thin film silicon technology from 1993. The two junctions consist of the amorphous silicon top cell and the microcrystalline silicon bottom cell. Micromorph is the brand name describing the amorphous/microcrystalline silicon tamdem cell. TEL Solar was the first to integrate boron doped zinc oxyde deposited by low pressure chemical vapour deposition as the Transparent Conductive Oxide layer, and the first to commercialize the high-efficiency Micromorph process. The majority of its customers upgraded from amorphous single junction to micromorph technology.TEL Solar is headquartered in Switzerland and has about 650 employees. The installed production capacity at its customer sites cumulates to 1 Giga Watt . TEL Solar maintains sales and service centers in the USA, Europe, China, Taiwan, Korea, Singapore and Japan.

Solar cells or solar modules of the so-called tandem type, i.e. stacked arrangements of photovoltaic absorber devices on a substrate with a textured surface are described. The thin film solar cell has a substrate comprising a textured surface, and a front electrode layer comprising a transparent conductive oxide adjacent to the textured surface, wherein the electrode layer has a thickness less than the roughness of the textured surface.

Micromorph tandem cells with stabilized efficiencies of 11.0% have been achieved on as-grown LPCVD ZnO front TCO at bottom cell thickness of just 1.3 m in combination with an antireflection concept. Applying an advanced LPCVD ZnO front TCO stabilized tandem cells of 10.6% have been realized at a bottom cell thickness of only 0.8 m. Implementing intermediate reflectors in Micromorph tandem cell devices allow for, compared to commercial SnO_(2), reduced optical losses when LPCVD ZnO is used. At present highest stabilized cell efficiency reached 11.3% incorporating an in-situ intermediate reflector with a bottom cell thickness of 1.6 m.
