SOLAR ELEMENT AND SOLAR ELEMENT MODULE Russian patent published in 2015 - IPC H01L31/04 

FIELD: power engineering.

SUBSTANCE: solar element, on which a passivating film is formed on a crystal silicon substrate, which has at least a p-n transition, and an electrode is formed by printing and thermal treatment of conducting paste. The specified solar element comprises: the first electrode, comprising an extraction electrode, which extracts photogenerated carriers from the silicon substrate, formed so that it contacts with the silicon substrate; and the second electrode, comprising a collector electrode, which collects carriers accumulated on the extraction electrode, formed so that it contacts with the first electrode. Apart from a point of contact between the first electrode and the second electrode at least the second electrode contacts with the silicon substrate only partially or never contacts.

EFFECT: invention reduces losses of charge at electrode/silicon borders, increases short-circuit current and voltage of an open circuit, gives improved characteristics to a solar element and reduces costs.
