Abstract
An n-type low-doped region and a first main-surface side highly doped region, which has an n-type dopant concentration higher than that in the n-type low-doped region, are provided in an n-type crystalline silicon substrate. The first main-surface side highly doped region is arranged between the n-type low-doped region and a p-type amorphous silicon layer.
