Charge Recombination and Thermoluminescence in Photosystem II [PDF]
Biophysical Journal, 2005 In the recombination process of Photosystem II (S(2)Q(A)(-)-->S(1)Q(A)) the limiting step is the electron transfer from the reduced primary acceptor pheophytin Ph(-) to the oxidized primary donor P(+) and the rate depends on the equilibrium constant between states S(2)PPhQ(A)(-) and S(1)P(+)Ph(-)Q(A).

Understanding Charge Recombination of TiO2 using Ultrafast mid-Infrared Spectroscopy: The Effect of Photogenerated Holes [PDF]
, 2022 We utilize mid-infrared probe to explore the mechanism for the dramatic charge recombination process of the photogenerated charges within the band gap of TiO2. Using the low-energy photons probes the free electrons in the conduction band of TiO2 and upon

Charge carrier recombination in the ITO/PEDOT:PSS/MEH-PPV/Al photodetector [PDF]
Hemijska Industrija, 2009 In this paper we investigate charge carrier recombination processes in polymer based photodetector ITO/PEDOT:PSS/MEH-PPV/Al. The major carriers are the hole polarons created by the photoexcitation in the active MEH-PPV film.
