Zusammenfassung:PHOTOVOLTAIC DEVICES A photovoltaic device including a composite down-converting layer disposed on the device, is presented. The composite down-converting layer includes down-converting material particles dispersed in a matrix. The size of the down-converting material particles is a function of a difference in respective refractive indices (An) of the down-converting material and the matrix such that: (i) for An less than about 0.05, the size of down-converting material particles is in a range from about 0.5 micron to about 10 microns, and (ii) for An at least about 0.05, the size of down-converting material particles is in a range from about I nanometer to about 500. A photovoltaic module having a plurality of such photovoltaic devices is also presented. 0 6 o o 0 0 000 000 0 0 0 0 o0 0 00 00000 00000 00 00 0 00 0
