The Arctic attracts the attention of many countries of the world, as it is rich in hydrocarbons. The polar people are faced with the problem of providing electricity. Traditionally, diesel generators are used in the Arctic, while electricity is costly, and the generators themselves pollute the environment. Many researchers use wind generators and solar power plants. Wind generators do not withstand severe frosts and strong winds. This study is devoted to the problem of choosing the type of solar cells that could work efficiently at low temperatures. [ABSTRACT FROM AUTHOR]

The Arctic attracts the attention of many countries of the world, as it is rich in hydrocarbons. Gas production in the circumpolar region is possible only from drilling platforms. One of the most important tasks on the platform is the task of ensuring the safe work of platform employees. Natural gas is explosive, as in a mixture with air at a certain concentration forms an explosive mixture. To monitor the concentration of natural gas in the most important parts of the drilling platform are sensors that record the concentration of gas and give control signals when a certain concentration level is exceeded. We have developed a mobile device that allows you to determine the concentration of natural gas in those places where there are no stationary sensors for monitoring the concentration.
