Patent ID: 8110246

Claim:
A method of producing a thin-film solar cell in which a pin or nip layer sequence is produced, further comprising the steps of successively depositing the following layers on a substrate: a) a microcrystalline p- or n-layer, b) an intermediate microcrystalline silicon I-layer applied by a hot-wire chemical-vapor deposition (HWCVD) method on the microcrystalline p- or n-layer a), c) an additional I-layer of microcrystalline silicon, which is formed by depositing on the intermediate microcrystalline silicon I-layer, by a plasma enhanced chemical vapor deposition (PECVD), a sputtering process, or a photo-CVD method whereby layers b) and c) together form an i-layer, and d) if a p-layer is present as the layer of step a), an n-layer, and if an n-layer is present as the layer of step a), a p-layer that is either microcrystalline or amorphous.
