Для прогноза производительности важно знать температуру окружающей среды, так как на выходные параметры системы влияет температура солнечных элементов, что выражается в температурных коэффициентах. Таким образом, варьируя температуру элементов с помощью конструктивных решений, таких как теплоотвод или фототеплопреобразовательная система, можно оптимизировать работу фотоэлектрической системы в целом. В статье продемонстрирована работа установки собственной разработки для измерения параметров солнечных элементов. Представлены результаты измерений по определению температурных коэффициентов тонкопленочных элементов. Для сравнения сделаны измерения выходных параметров монокристаллических и тонкопленочных фотоэлектрических модулей (ФЭМ) на основе аморфного кремния CdTe и CIGS при различных значениях температуры - от 20 °С до 80 °C.</p><p>Рассчитано изменение мощности ФЭМ при различных рабочих температурах по сравнению со стандартными условиями тестирования (STC). Измеренные таким образом параметры были нормированы к STC. Представлены температурные зависимости нормализованных значений максимальной выходной мощности, коэффициента заполнения, силы тока короткого замыкания и напряжения холостого хода. С повышением температуры во всех модулях наблюдалось уменьшение напряжения холостого хода. Наиболее резкое снижение коэффициента заполнения с повышением температуры зафиксировано в монокристаллическом модуле, которое в совокупности со снижением напряжения холостого хода показало самое большое снижение выходной мощности - 15,9 %, 20,4 % и 25,1 % при 60 °C, 70 °C и 80 °C соответственно. Доказано, что все ФЭМ на основе тонкопленочных технологий имеют меньшие значения температурного коэффициента выходной мощности по сравнению с монокристаллическими модулями, наименьшее из них у CdTe.</p><p>Определены задачи дальнейшего технического и программного усовершенствования разработанной установки для обеспечения динамического изменения интенсивности освещения, температуры и скорости ветра по задаваемой программе.</p></abstract><trans-abstract xml:lang="en"><p>The main parameter to ensure the optimal operation of the photovoltaic system is to determine its position of this system in accordance with the available solar radiation in the location. Nevertheless, in order to predict the performance of a photovoltaic system, it is important to know the ambient temperature, since the temperature of solar cells affects the output parameters of the system, which is expressed in temperature coefficients. Thus, it is possible to optimize the operation of the photovoltaic system by varying the temperature of the elements using design solutions such as a heat sink or photothermal conversion system.</p><p>The article demonstrates the operation of own development installation for measuring the parameters of solar cells. The results of measurements to determine the temperature coefficients of thin-film elements using this installation are presented. For comparison, we have measured the output parameters of a monocrystalline modules and thin-film photovoltaic modules (PM) based on amorphous silicon, CdTe, and CIGS at various temperatures from 20 to 80 °C.</p><p>The changes in the output power of PMs at various operating temperatures are calculated in comparison with the values under standard testing conditions (STC). The parameters measured at various temperatures are normalized to STC. The temperature dependences of the normalized values of the maximum output power, fill factor, short circuit current, and open circuit voltage are presented. Decrease in the open circuit voltage is observed with an increase in temperature in all modules. The sharpest decrease in the fill factor with increasing temperature is observed in the monocrystalline module, in combination with a decrease in open-circuit voltage, it showed the biggest decrease in output power, 15.9%, 20.4% and 25.1% at temperatures of 60 °C, 70 °C and 80 °C, respectively. It is proved that all PMs based on thin-film technologies have smaller values of the temperature coefficient of the output power in comparison with a monocrystalline modules, the smallest of which is for CdTe.</p><p>The further tasks are set to develop hardware and software for improvement of the installation to provide the dynamic changes in the intensity of illumination, temperature and wind speed defined by a program.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тонкопленочные элементы</kwd><kwd>солнечные элементы</kwd><kwd>фотоэлектрический модуль</kwd><kwd>ВАХ</kwd><kwd>температурный коэффициент</kwd><kwd>кристаллический кремний</kwd><kwd>аморфный кремний</kwd><kwd>теллурид кадмия</kwd><kwd>CdTe</kwd><kwd>CIGS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thin-film cells</kwd><kwd>solar cells</kwd><kwd>photovoltaic modules</kwd><kwd>CVC</kwd><kwd>temperature coefficient</kwd><kwd>crystalline silicon</kwd><kwd>amorphous silicon</kwd><kwd>cadmium telluride</kwd><kwd>CdTe</kwd><kwd>CIGS</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sample, T.
