Beschreibung
Zusammenfassung:	A solar cell having an improved structure of rear surface containing a p-type doped region, , a dense metal layer, a loose metal layer, at least one bus bar opening and solderable material on or within the bus bar opening. The solderable material contacts with the dense metal layer. A method for making such solar cells and a solar module and solar system composed of such one or more solar cells are also disclosed in the present invention.
