Abstract:
A method of manufacturing a tandem thin-film solar cell including a plurality of photoelectric conversion units stacked on a substrate, said photoelectric conversion units each including a p-type layer, an i-type photoelectric conversion layer and an n-type layer formed in this order from a light-incident side of said solar cell, and at least a rear unit among said photoelectric conversion units furthest from the light-incident side being a crystalline unit including a crystalline i-type photoelectric conversion layer, said method comprising the steps of:forming at least one of said units on said substrate by plasma CVD and immediately thereafter forming an i-type boundary layer to a thickness of at most 5 nm by plasma CVD; and removing thereafter said substrate into the atmosphere to expose a surface of said i-type boundary layer to the atmosphere and then forming a crystalline unit on said i-type boundary layer by plasma CVD.
