DEVICE AND METHOD OF MAKING DOUBLE-SIDED SILICON MATRIX SOLAR CELL Russian patent published in 2017 - IPC H01L31/42 H01L31/18 

FIELD: electricity.

SUBSTANCE: invention relates to devices converting electromagnetic radiation energy into electrical energy, in particular, to silicon solar cells and technology of their production. According to the invention in silicic bifacial solar cell made in the form of matrix from subsequently commuted micro-photocells with n⁺-p-p⁺ (p⁺-n-n⁺)- structure base width of which is comparable with diffusion length of minority charge carriers in base region, and planes of p-n-junctions are perpendicular to working surfaces, working surfaces have insulating passivating chloride film of one of zinc, aluminium, beryllium, tantalum, hafnium, zirconium or thorium metal applied by method of chemical deposition from organic solutions and antireflection coating from polymer silane film applied by method of chemical deposition from organic-substituted low-molecular silanes.

EFFECT: invention improves conversion efficiency and efficiency of silicon bifacial matrix solar cell and reduces its cost.
