Processes of excitation and deactivation of excitation energy in organic wavelength transformers cooperating with solar photovoltaic cells.
The measurements of maximal power increase of silicon photovoltaic cells coated with polymethyl methacrylate foil containing Rhodamine-6G were carried out. The photoelements were irradiated from the solar radiation simulator. Two different amplification values were obtained: ~ 20% and 50%. An equation that describes the change of photoluminescence intensity as a function of fluorescent molecules and that takes into account the reabsorption and secondary fluorescence is derived. The expression obtained is compared with the results of photoluminescence measurements for Rhodamine-6G and 2,5-bis[5'-tert-butylbenzoxazol-(2')]-thiopen; good agreement is evident.
