| EPHOCELL is a 7th Framework Programme funded project.The main objective of this project is the study of energy down shifting and up conversion processes with the aim to modify the wavelength of solar photons by means of a tunable molecular system based on organic compounds and metal complexes. This molecular system will enable improved matching between the spectrum of solar radiation and the absorbance of the photovoltaic (PV) materials through the conversion of photon energy in two directions: downshifting: high energy UV (280 – 400nm) to Visible (400-700nm) and up conversion of low energy NIR (700-840 nm) to Visible. The concentration of the solar radiation in the absorption band of the PV may determine an increase in number of photons able to excite the PV materials and, in consequence, the electrical energy produced by the solar cells. |
