Optical measurements of charge-carrier mobilities in photorefractive sillenite crystals
Photorefractive crystals exhibit large optical nonlinearities1 and have great potential in optical data processing.2 The extrinsic photorefractive effect in these electro-optic and photoconductive materials is rather well understood. The band-transport model' has been successfully employed to describe photorefraction in crystals such as the sillenite compounds, Bi12SiO2 0 and Bi12GeO 2 0 (BGO)....
متن کاملFinite-Bandwidth Calculations for Charge Carrier Mobility in Organic Crystals
Finite-bandwidth effects on the temperature dependence of the mobility of injected carriers in pure organic crystals are explored for a simplifed case of impurity scattering. Temperature-dependent bandwidth effects are discussed briefly through a simplified combination of band and polaronic concepts.
متن کاملKinetics and pathways of charge recombination in photosystem II.
The mechanism of charge recombination of the S(2)Q(A)(-) state in photosystem II was investigated by modifying the free energy gap between the quinone acceptor Q(A) and the primary pheophytin acceptor Ph. This was done either by changing the midpoint potential of Ph (using mutants of the cyanobacterium Synechocystis with a modified hydrogen bond to this cofactor), or that of Q(A) (using differe...
متن کاملCharge Carrier Recombination in Bulk Heterojunction Organic Solar Cells
Photovoltaic phenomenon was first observed by E. Becquerel (Becquerel) in 1839. He observed the electric current-lit silver electrode, immersed in the electrolyte. In 1894, taking advantage of the observed photoconductivity phenomenon in amorphous selenium the semiconductor solar cell was developed. The very first silicon p-n junction solar cell was made in 1954, energy conversion efficiency of...
متن کاملTheoretical-computational modeling of photo-induced charge separation spectra and charge recombination kinetics in solution.
In this study we propose a theoretical-computational method, essentially based on molecular dynamics simulations and quantum-chemical calculations, for modelling the photo-induced charge separation (CS) and the subsequent charge recombination (CR) processes in solution. In particular we have reproduced the low-energy UV-Vis spectra of systems composed by an aromatic species (Ar = benzene or ind...
