A Simple and Cost-Effective Thiophene-Benzene-Thiophene Based Hole Transporting Material for Stable Perovskite Solar Cells

Key Points

• To develop a cost-effective hole transporting material (HTM) that enhances the efficiency and stability of perovskite solar cells.
• Synthesis of thiophene-benzene-thiophene based HTM
• Performance evaluation of the new HTM in PSCs
• Comparison with conventional HTM (Spiro-OMeTAD)
• The new HTM showed improved intrinsic conductivity compared to Spiro-OMeTAD
• Enhanced thermal stability was observed in solar cells using the new material
• Perovskite solar cells exhibited higher overall efficiency with the thiophene-benzene-thiophene HTM
