Sunlight passes through the transparent electrode into the dye layer where it can excite electrons that then flow into the titanium dioxide.
22.
The companies that sell power to California utilities have seen their stock prices gyrate like excited electrons in the past few days.
23.
The figure is a simplified representation showing the excited electron and the hole in an exciton entity and the corresponding energy levels.
24.
The initial phenomenon of the excited electron is similar to the photoelectric effect and ( particularly with gamma rays ) the Compton effect.
25.
In the opposite process, when excited electron-hole pairs undergo recombination, photons are generated with energies that correspond to the magnitude of the bandgap.
26.
"' Photoinduced electron transfer "'( PET ) is an excited state electron transfer process by which excited electron is transferred from donor to acceptor.
27.
The ease of exciting electrons in the semiconductor from the valence band to the conduction band depends on the band gap between the bands.
28.
When placed in the sun, photons of the sunlight can excite electrons on the p-type side of the semiconductor, a process known as photoexcitation.
29.
The membranes of the thylakoid contain photosystems I and II which harvest solar energy to excite electrons which travel down the electron transport chain.
30.
Similarly, blue light might excite electrons at other places in the process that should " not " have been excited, ruining the chemical reaction.
