Description

technical field [0001] The present invention relates to a thin-film solar cell, more particularly to a see-through thin-film solar cell. Background technique [0002] A solar cell is a device that converts light energy into electrical energy based on the properties of semiconductors. [0003] A solar cell has a P-N junction structure in which a positive (P) type semiconductor and a negative (N) type semiconductor are joined to each other. When sunlight is incident on the solar cell, holes (+) and electrons (-) are generated in the semiconductor by the energy of the incident sunlight. At this time, due to the electric field generated in the PN junction, holes (+) move to the side opposite to the P-type semiconductor, and electrons (-) move to the N-type semiconductor, thereby generating a potential. The solar cell generates electricity based on this potential. [0004] Solar cells are classified into thin film type solar cells and wafer type solar cells. [0005] A thin f...
