Abstract :
In the paper the process of formation of porous silicon on textured surface of solar cells is studied. It is shown that porous layers formed by the etchant HF:NaNO2:H2O, can be successfully applied in photovoltaic technology as antireflective coating . Technology of the obtaining of porous layer by chemical etching can be applied after contact grid formation. It is shown that as a result of a porous layer efficiency of solar cells increased by 20-30% on average.
