Paper summary by Mr Patrick Tapping: Optical pumping of poly(3-hexylthiophene) singlet excitons induces charge carrier generation
Three-pulse ultrafast laser spectroscopy is used to study the excited states of the conjugated polymer poly(3-hexylthiophene) (P3HT) in solution on the femtosecond time scale. P3HT is a much studied material used to produce plastic solar cells. In this work we show that a secondary laser excitation pulse can produce charged species on the isolated polymer chains.
