Abstract
The results of a study of the structural features and electrical properties of Si(Al) through thermomigration p-channels in a silicon wafer are presented. Structural studies were performed using X-ray methods of projection topography, diffraction reflection curves and scanning electron microscopy. It is shown that the channel-matrix interface is coherent without the formation of mismatch dislocations. The possibility of using an array of thermomigration p-channels of 15 elements to form a monolithic photovoltaic solar module in a Si(111) silicon wafer based on p-channels with a width of 100 microns with walls in the plane is shown. The monolithic solar module has a conversion efficiency of 13.1%, an idle voltage of 8.5 V and a short-circuit current density of 33 mA/cm².
