Investigations of solar cells with porous silicon as antireflection layer

The possibility of using porous silicon layers as antireflection coating in stead of the antireflection coatings in common silicon solar cells was inve stigated. A technology for the manufacture of porous silicon antireflection layers was developed. The comparison of the photovoltaic and optical chara cteristics of investigated samples of solar cells with ZnS antireflection c oating and with porous silicon antireflection coating is presented. It is s hown that the formation of the porous layer under optimal technological reg imes leads to significant improvement of the main photovoltaic parameters-s hort-circuit current and open-circuit voltage.
