the bifacial converter of solar energy in electrical on the base of isotype heterojunction

The method of n+Si/nSi/SiO2 /n+ITO bifacial solar cells fabrication by pyrolitical spraying was elaborated. This structure contains only isotype junctions. The spectral sensitivity is situated in the 350–1200nm wavelength region and is independent on the illumination direction. The photoelectrical parameters of solar cells obtained on silicon wafer (4,5 Ohm.cm) are following: at frontal illumination Voc=0,425V, Isc=32,63mA/cm2 , FF=68,3%, Eff=9,47%; at rear illumination Voc=0,392V, Isc =13,20mA/cm2 , FF=69,3%, Eff=3,60%
