Title:
SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2016/194301
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, a solar cell 10 is provided with an n-type crystalline silicon substrate 11, and a passivation layer 20 formed on the light receiving surface of the substrate, said passivation layer having a carrier generating function. The n-type crystalline silicon substrate 11 has a doped layer in the vicinity of an interface to the passivation layer 20, said doped layer being doped to have a conductivity type equal to that of the substrate, and being doped at a dopant concentration equal to or higher than 1×1017 cm-3. The average value of the dopant concentration of the doped layer is 1×1017-1×1020 cm-3, and the thickness of the doped layer is equal to or less than 200 nm.
