Abstract
An amorphous silicon solar cell includes a substrate, a transparent electrode formed on this substrate, a power-generating film formed on this transparent electrode, and a back-side electrode formed on this power-generating film. The power-generating film is formed by sequentially stacking p-type/i-type/n-type hydrogenated amorphous silicon layers. The defect density of the i-type hydrogenated amorphous silicon layer is less than 10.sup.15 defects/cc.
