A process for producing a photovoltaic device, wherein when providing an n-type amorphous silicon layer on an i-type amorphous silicon layer, a desired crystallization ratio can be achieved without reducing the deposition rate. The production process comprises 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 the deposition conditions for the first n-layer formation step are conditions that yield a higher crystallization ratio than the deposition conditions for the second n-layer formation step, for deposition onto the same base material substrate.

Process for producing photovoltaic device

A method of manufacturing a solar cell panel, includes steps (a) to (e). The step (a) is a step of forming a solar cell module by laminating solar cell films on a transparency substrate. The step (b) is a step of performing an inspection of electric power generation on the solar cell module. The step (c) is a step of forming a solar cell panel by executing a panel formation on the solar cell module. The step (d) is a step of cleaning a light incidence surface of the solar cell panel. The step (e) is a step of performing an inspection of electric power generation on the solar cell panel. The step (d) is executed immediately before the step (e).
