Verfahren zur Rauhätzung von Siliziumsolarzellen

摘要

The present invention relates to a novel process for producing textured surfaces on multicrystalline, tricrystalline and monocrystalline silicon surfaces of solar cells or on silicon substrates which are used for photovoltaic purposes. It relates in particular to an etching process and an etching agent for producing a textured surface on a silicon substrate.
