The task of reducing the cost of an energy unit obtained by the photovoltaic method remains relevant. One of the effective methods of reducing the production cost of energy units is to use installations that concentrate solar irradiation. In this study, the authors develop design and technological solutions and use silicon backside contact photoconverters with a rear placement of the collector p–n-junction and both contact electrodes to make a solar photovoltaic module of the required size. This photovoltaic module with front surface dimensions of 0.42x0.05 m2 is intended for use in a solar power plant with the parabola-cylindrical concentrator. The first stage of experimental and theoretical research of photovoltaic characteristics of the solar module is carried out in the conditions of unconcentrated and weakly concentrated solar irradiation. It is established that the used solar photoconverters have fairly low values of the series resistance and the solar photovoltaic module has a sufficiently high efficiency of the photovoltaic conversion. It is planned to further test the developed solar module in the conditions of natural sunlight irradiation concentrated 20-fold, which will allow determining the ways to improve its characteristics.

Keywords: silicon backside contact photoconverters, solar photovoltaic module, concentrated solar irradiation.
