Area of Science:

• Materials Science
• Photovoltaics
• Organic Chemistry

Background:

• Dye-sensitized solar cells (DSSCs) are a promising photovoltaic technology.
• Developing efficient p-type DSSCs is crucial for complementary solar cell applications.
• Arylamine-based compounds are explored as potential sensitizers.

Purpose of the Study:

• To synthesize novel arylamine-based sensitizers for p-type DSSCs.
• To evaluate the performance of these new sensitizers in p-type DSSC devices.
• To investigate the impact of sensitizer structure on device efficiency.

Main Methods:

• Synthesis of new arylamine-based organic molecules.
• Fabrication of p-type dye-sensitized solar cells using synthesized sensitizers.
• Characterization of photovoltaic performance, including open-circuit voltage (Voc), short-circuit current (Jsc), and energy conversion efficiency (PCE).

Main Results:

• Successful synthesis of novel arylamine-based sensitizers.
• The best performing p-type DSSC achieved a conversion efficiency of approximately 0.1%.
• Sensitizers featuring two anchoring carboxylic acid groups demonstrated superior performance.

Conclusions:

• The synthesized arylamine sensitizers are effective for p-type DSSCs.
• Dual anchoring groups enhance key photovoltaic parameters like Voc, Jsc, and PCE.
• Further development of arylamine sensitizers holds potential for advancing p-type DSSC technology.
