Abstract
A method for manufacturing a silicon-based thin film solar cell including a crystalline silicon photoelectric conversion unit which contains a p-type layer (), a crystalline i-type silicon photoelectric conversion layer (), and an n-type layer () stacked in this order from a transparent substrate side is provided. In one example, an n-type silicon-based thin film layer () is formed on the crystalline i-type silicon photoelectric conversion layer (), the n-type silicon-based thin film layer () having an n-type silicon alloy layer having a film thickness of 1-12 nm and being in contact with the crystalline i-type silicon photoelectric conversion layer.
