  • High efficiency micromorph tandem cells
    Patent number: 8846434
    Abstract: A method for manufacturing a micromorph tandem cell is disclosed. The micromorph tandem cell comprises a ?c-Si:H bottom cell and an a-Si:H top cell, an LPCVD ZnO front contact layer and a ZnO back contact in combination with a white reflector. The method comprises the steps of applying an AR—Anti-Reflecting—concept to the micromorph tandem cell; implementing an intermediate reflector in the micromorph tandem cell. The micromorph tandem cell can achieve a stabilized efficiency of 10.6%.

  • METHOD FOR HYDROGEN PLASMA TREATMENT OF A TRANSPARENT CONDUCTIVE OXIDE (TCO) LAYER
    Publication number: 20130337603
    Abstract: A method for fabricating a thin film solar device that includes providing a substrate having a transparent conductive oxide (TCO) layer deposited on a surface of the substrate, the TCO layer having an as deposited sheet resistance. At least a portion of a surface of the TCO layer is exposed to a hydrogen plasma under conditions which result in a treated TCO layer having a reduced sheet resistance which is at least 10% less than the as deposited sheet resistance.

  • LARGE-AREA THIN-FILM-SILICON PHOTOVOLTAIC MODULES
    Publication number: 20110240107
    Abstract: 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 SnO2, 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.
