Riddle of missing efficiency in zinc oxide-based dye-sensitised solar cells solved

To convert solar energy into electricity or solar fuels, you need specialized 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 of researchers 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.
