Title:
SOLAR CELL ELEMENT, SOLAR CELL MODULE, AND METHOD FOR MANUFACTURING SOLAR CELL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2024/053603
Kind Code:
A1
Abstract:
An embodiment of a solar cell element comprises a first electrode part (106), a photoelectric conversion unit (104), and a first carrier transport unit (105). The first carrier transport unit (105) is positioned between the first electrode part (106) and the photoelectric conversion unit (104). The first carrier transport unit (105) has a first surface (CF1) in contact with the photoelectric conversion unit (104) and a second surface (CF2) in contact with the first electrode part (106). In the first carrier transport unit (105), a first level (EL1), which is an energy level of the highest occupied molecular orbit of a first interface region (Ab1) along the first surface (CF1), is lower than a second level (EL2), which is an energy level of the highest occupied molecular orbit of a second interface region (Ab2) along the second surface (CF2).
