In the last decades increased awareness for environmental problems, climate change, and limited energy sources has escalated research efforts around the globe to investigate photovoltaics as an alternative energy source. The sun offers an enormous potential for solar energy conversion, which makes photovoltaics quite attractive among green energy sources. However, there is still not an ultimate photovoltaic...
The authors developed a near-field heterodyne transient grating (NF-HD-TG) technique using femtosecond pulsed lasers to study ultrafast photoexcited carrier dynamics in semiconductor nanomaterials including TiO2, deposited CdSe and CdS QDs on nanostructured electrodes, and nanocrystalline silicon. Chemical deposition method was used to adsorb CdSe QDs and CdS QDs onto nanostructured TiO2 and SnO2...
