Stabilization of planar heterojunction solar cells using a dimethyl sulfoxide treated hole transport layer

Key Points

• This research aims to evaluate the stabilization of heterojunction solar cells through a modified hole transport layer.
• Utilized dimethyl sulfoxide (DMSO) to treat the hole transport layer of the cells.
• Conducted efficiency and stability assessments of the treated solar cells.
• Compared performance metrics against untreated cells.
• DMSO treatment resulted in enhanced cell stability over extended periods.
• Significant improvements in efficiency were observed in treated solar cells compared to controls.
• The findings suggest that DMSO effectively improves the performance and longevity of heterojunction solar cells.
