The scientific activity of professor Węgierek is related to the use of ion techniques to modify the electrical properties of semiconductors, especially silicon and gallium arsenide, and to study the thermal stability of their parameters in terms of the possibility of application in microelectronics and photovoltaic cells. In recent years, the area of research interests also includes modern switchgear as well as monitoring and control systems used in energy distribution systems to improve power supply reliability and reduce greenhouse gas emissions.
His research goal is to use ion implantation to increase the efficiency of electricity generation in photovoltaic cells. The problem of determining the influence of the type and concentration of doped semiconductor, implantation parameters, i.e. the type, dose and energy of ions, as well as the method, time and temperature of post-implantation annealing on the dielectric permeability of silicon, was the subject of research conducted by professor Węgierek, while he was still a doctoral student. Another line of research undertaken concerned the insulating properties of silicon and gallium arsenide modified by ionic techniques, with particular emphasis on the temperature stability of the parameters characterizing them. In turn, the most important result of the research work carried out, was the use of ion implantation to produce insulating layers in devices and microelectronic systems made on the basis of silicon and gallium arsenide. Research conducted for many years on changing the electrical properties of silicon, through the use of neon ion implantation, has led to the development of an author's method for producing and identifying additional energy levels in the band structure of silicon, which improves the efficiency of photovoltaic cells made on its basis.
