Patent ID: 8088641

Claim:
A process for producing a photovoltaic device, the process comprising: a p-layer formation step of depositing a p-type amorphous silicon layer, an i-layer formation step of depositing an i-type amorphous silicon layer on the p-type amorphous silicon layer, and an n-layer formation step of depositing an n-type amorphous silicon layer on the i-type amorphous silicon layer, wherein the n-layer formation step comprises: a first n-layer formation step of depositing a first n-layer on the i-type amorphous silicon layer, and a second n-layer formation step of depositing a second n-layer on the first n-layer, and deposition conditions for the first n-layer formation step are conditions that yield a higher crystallization ratio than deposition conditions for the second n-layer formation step for deposition onto an identical base material substrate.
