Title:
SOLAR CELL AND SOLAR CELL MODULE
Document Type and Number:
Japanese Patent JP2020167238
Kind Code:
A
Abstract:
To provide a solar cell and a module having improved power generation characteristics.SOLUTION: A solar cell 10 comprises: a semiconductor substrate 20 of a first conductive type including a first main surface 21 and a second main surface 22; a third amorphous silicon layer 41a arranged on the second main surface 22; and a fourth amorphous silicon layer 42p of a second conductive type different from the first conductive type arranged on the third amorphous silicon layer 41a. The first conductive type impurity concentration of the third amorphous silicon layer 41a is higher than the first conductive type impurity concentration of the semiconductor substrate 20 and lower than the second conductive type impurity concentration of the fourth amorphous silicon layer 42p.SELECTED DRAWING: Figure 3
