The use of solar cells with a bifacial contact grid under the conditions of Kazakhstan

The paper reports on the results of simulations of output characteristics of silicon solar cells based on the amorphous silicon–crystalline silicon heterojunction. In addition, the prospect of utilizing high-efficiency bifacial silicon solar modules for various orientational configurations is evaluated. The evaluations are based on the geographical location of the city of Astana (Kazakhstan) located at 51.2$^\circ$ N and 71.4$^\circ$ E at an altitude of 354 m above the sea level.
