Organic photovoltaics have pushed for the development of photonic materials capable of solution processing for large area low-cost fabrication on light-weight flexible substrates.
Reynolds and his co-workers reported the development of a new p-type polymer with deep HOMO and LUMO energy levels that enabled the fabrication of high open circuit voltage polymer solar cells when blended with fullerene derivatives.
