FIELD: power engineering.
SUBSTANCE: invention refers to solar engineering and can be used for manufacturing solar cells. Essence of invention is that in the present solar cell formed on high-alloyed substrate the emitter is the main area absorbing and generating carriers, at that, epitaxial emitter consists of two areas each of which has dopant profile variable as to thickness. Low-alloyed area adjoining pn-transition provides the main light absorption, and high-alloyed area serves for forming a contact. Single-crystalline or multi-crystalline silicon of p- or n- conductivity can be used as silicon substrate.
EFFECT: this solar element design allows increasing efficiency of solar energy conversion.
