Study and Analysis of Semiconductors for the Development of Two-layer Solar Cells

Abstract

In the field of renewable energies, researchers have always looked for the improvement of the conversion method in solar cells, due to the fact that only 14% of the electrical potential is being used. That is why in order to increase efficiency, different designs and materials have been studied. One of the most viable ways is the technology of multilayer solar cells, which the recent investigations focused due to the fact this technique allows the possibility of achieving efficiencies above 30%. Despite the above, the problem of this technique is the cost of manufacturing, which compared to the commercial cells, is inferior in benefit -cost relationship. For this reason, this paper shows a study of different semiconductors to design a two-layer solar cell, with the aim of selecting the best combination of semiconductors according to their own characteristics and results according to the described method.
