Ultralow-work-function lithium oxide (LiO x ) as electron-selective contact for silicon heterojunction solar cell

Key Points

• The research aims to evaluate lithium oxide as an effective electron-selective contact for silicon heterojunction solar cells.
• Used ultrathin lithium oxide (LiO x ) with a work function of 2.39 eV.
• Measured contact resistivity under controlled conditions.
• Achieved a contact resistivity of 7.17 mΩ cm².
• Demonstrated enhanced electron selectivity in solar cells.
