CIGS solar cells with efficiency 10,1% on perlite galssceramic substrates

For the first time thin film solar cells with $\mathrm{CuInGaSe_2}$ absorber layer were formed on a specially designed non-conductive ceramic substrates on the basis of pearlite to produce photovoltaic devices fully integrated into building constructions. This glass ceramic satisfies the physical demands of the substrate material as well as the requirements of cost reduction of solar cells production. This paper presents preliminary results which show that these type solar cells with the efficiency higher than 10% may be designed.
