A new approach to increasing the efficiency of silicon solar cells (SCs) is presented, which consists in the creation of surface light-trapping structures with a high antireflection ability in the form of systems of pointed whiskers (NCs) with coaxial p-n junctions. The coaxial geometry of the p-n junction is justified in terms of the efficiency of collection and separation of minority charge carriers (NCCs) due to the built-in electric field across the junction. Received solar cells with improved photoelectric characteristics and an efficiency factor (COP) of 20.43%. Keywords: solar cell, light absorption, p-n junction, silicon.
