Annotation. Activity in the field of the use of semiconductor materials in the field of energy technologies today opens up a large number of opportunities, which indicates the need for further more active development and use. In addition, it is also worth paying attention to the use of a large number of different materials, among which individual representatives may stand out, dramatically increasing the overall efficiency of the entire semiconductor structure and are currently in greater priority for such a measurement in the face of binary, ternary, etc. chemical compounds.
Keywords: cadmium telluride, semiconductor elements, photovoltaic devices, efficiency, production technology, industrialization.
Аннотация. Активность в области использования полупроводниковых материалов в области энергетических технологий на сегодняшний день открывает большое количество возможностей, что говорит о необходимости дальнейшего более активного развития и использования. Кроме того, стоит также обращать внимание и на применение большого количества различных материалов среди коих могут выделяться отдельные представители, резко повышающие общую эффективность всей полупроводниковой конструкции и находящиеся на данный момент в большем приоритете по подобному измерению в лице бинарных, тернарных и т. д. химический соединений.
Ключевые слова: теллурид кадмия, полупроводниковые элементы, фотоэлектрические устройства, эффективность, технология производства, индустриализация.
Photovoltaic cells, as is known, based on the method of generating electrical energy due to the low energy that must be applied in the face of a particular radiation, operate according to the laws of photovoltaic phenomena (partial equations) (1—2).
And before giving some conclusions about this or that element, which is recognized as the main one for the semiconductor element being created, it is worth considering this chemical compound according to its various parameters. In this case, the role of such a compound is played by cadmium telluride (Fig. 1), which is a binary compound of cadmium and tellurium, and is also considered a semiconductor of the 2-a and 6-b groups with a band gap at temperatures of 300 K at 1.49 eV.
