Implication
Review demonstrates ultrafast photo-induced charge transfer and 3% efficiency in plastic solar cells, highlighting their potential for terrestrial energy conversion.
Key Points
- Review recent advances in conjugated-polymer-based photovoltaic elements and examine the underlying photophysics of photo-induced charge transfer.
- Reviewed donor-acceptor mechanisms between semiconducting conjugated polymers and acceptor molecules such as Buckminsterfullerene (C60).
- Evaluated device architectures and operational parameters for terrestrial solar energy conversion applications.
- Photo-induced charge transfer occurs within 100 femtoseconds with a quantum efficiency approaching unity.
- The resulting charge-separated state displays metastability lasting up to milliseconds at 80 Kelvin.
- Conjugated-polymer photovoltaic device architectures demonstrate up to 3% power conversion efficiency.
