Riddle of missing efficiency in zinc oxide-based dye-sensitized solar cells solved
To convert solar energy into electricity or solar fuels, you need specialised systems of materials such as those consisting of organic and inorganic thin films.
Processes at the junction of these films play a decisive role in converting the solar energy. Now a team at HZB headed by Prof. Emad Aziz has used ultra-short laser pulses and observed for the first time directly how boundary states form between the organic dye molecules and a zinc-oxide semiconductor layer, temporarily trapping the charge carriers.http://www.pvbuzz.com/zinc-oxide-zno-dye-sensitised-solar-cells/
