Organic solar cells: Evolution of the morphological and electronic properties as a function of steric hindrance from the acceptor side groups

Key Points

• To investigate how steric hindrance from acceptor side groups affects the morphological and electronic properties of organic solar cells.
• Analyzed morphological changes in organic solar cells with varying steric hindrance from acceptor side groups.
• Measured electronic property variations in response to different acceptor modifications.
• Assessed non-radiative recombination losses in solar cell efficiency.
• Increased steric hindrance in acceptor side groups reduced non-radiative recombination losses.
• Morphological improvements led to enhanced electronic properties in organic solar cells.
• Optimal side group modifications showed potential for higher energy conversion efficiency.
