Zusammenfassung:	PURPOSE: An amorphous silicon solar cell is provided, in which the defect density of an i-type hydrogenated amorphous silicon layer forming a power-generating layer is less than 10¬(15) defects/cc and which thereby can raise the initial efficiency without lowering the productivity and achieve high stabilization efficiency compared to conventional solar cells. CONSTITUTION: An amorphous silicon solar cell includes a substrate(11), a transparent electrode(12) formed on this substrate(11), a power-generating film(16) formed on this transparent electrode(12), and a back-side electrode(17) formed on this power-generating film(16). The power-generating film(16) is formed by sequentially stacking p-type/i-type/n-type hydrogenated amorphous silicon layers (13,14,15). The defect density of the i-type hydrogenated amorphous silicon layer(14) is less than 10¬15 defects/cc.
