The invention relates to the field of photoelectric devices.
Materials known to the state of the art for forming photoelectric devices are generally semiconductor materials. They are, for example, monocrystalline materials such as silicon or gallium arsenide, or polycrystalline silicon or other amorphous materials.
Other materials exist, such as colorant-based materials.
Another known solution is the use of organic materials.
At present, none of the known solutions is completely satisfactory. Devices having better energy yield or better sensitivity or low design cost are sought after. The world of industry, therefore, is searching for new ways of producing such devices…
Because the particle has a temperature controlled electronic spin-state transition, below a transition temperature, the particle is preferably in a first electronic spin state between the high electronic spin state and the low electronic spin state and, above this transition temperature, the particle is preferably in the other of the two electronic spin states.
In particular, in a preferred case, below a transition temperature, the particle is in the low electronic spin state and, above this transition temperature, the particle is in the high electronic spin state. The transition temperature can have different values depending on whether the transition occurs by increasing the temperature of by decreasing the temperature.
In this way, the particle in contact with the two electrodes has, in darkness, a conductivity comparable to that of a semiconductor material.
This patent family is the consequence of research carried on triazole-based molecules discovered by the laboratory ICMCB which turned out to have photoconductive and photovoltaic properties. Said molecules are already patented and licensed.
Photoconductive (photodiode) and photovoltaic devices.
