The present work reports the study and fabrication of violet polished and textunzed (viole~ black) silicon solar cells The cells were made with n-type silicon single crystal using boron diffusion m a reducing atmosphere. These cells are 16 cm 2 In area and have Va-A1 contacts in comb form and a silicon nltrlde antweflection coating These cells were studied using IV measurement In natural and artificml conditions, as well as spectral response
The measurements show that using the technologically designed processes, It is possible to make single crystal silicon solar cells up to 16% efficiency with a high photovoltalc yield, spectral response up to 250 nm, small recombination current and high values of perfect recomblnatwe factor This work includes the description and analysis of methods mentioned before and a sketch of the technology

In this paper the present state of development of high efficiency silicon solar cells for use at high concentration levels (20X -100X) is described. The design factors and process steps leading to the best performance within the available process technology are analyzed. The cell efficiency has exce
Energy conversion efficiencies of 18% and 19.4% at 0.1 W cm -2 and 1 W cm-2 respectively were measured for a luminescent solar concentrator cell under an air mass one solar spectrum. This cell was designed for operation under illumination of 600 nm wavelength and 1 W cm -2. From these results and sp
