The efficiency of solar cells increased by 40 percent

Niğde Ömer Halisdemir University Zübeyde Hanım Vocational School of Health Services Health Services Department of Medical Services and Techniques Optician Program Lecturer Assoc. DR. Yavuz Atasoy told the AA reporter that they have been working on thin film solar cells for about four years in their TÜBİTAK-supported projects.

Stating that they have developed a project to increase the efficiency of solar cells at the university's Central Research Laboratory for Nanotechnology Applications and Research, Atasoy explained that within this framework they have studied the cell performance of solar cells obtained by combining copper , zinc, tin and selenium would be formed elements.

Atasoy pointed out that they improve the structural and optoelectronic properties of these materials by doping different types of atoms, saying:

“We actually used different types of materials. Our goal is to improve the properties of the structures by adding materials such as manganese, germanium and silver to these structures. In this way, we achieved an increase in efficiency of 40 percent. Solar power plants and many more.” Solar applications consist of silicon-based solar cells.

There are some differences between silicon-based solar cells and the thin film solar cells we focus on. We can talk about some advantages of thin film based cells. “The silicon substrate used in silicon-based solar cells in particular has a thickness of about 200 micrometers, but the thin films we use are only 1 percent of that, so 1 to 2 micrometers, and we can achieve the same cell performance with thin films. “film-based cells.”

Atasoy stated that thin-film-based solar cells can absorb a significant portion of the sun's rays even at a thickness of 1 to 2 micrometers, and that the abundance of elements used in nature reduces costs.

Atasoy explained that thin film solar cell applications can be applied to both flexible substrates and glass substrates: “In this sense, we believe that small electronic items that we use in daily life, such as phones and Bluetooth headsets, will be able to do so.” portable solar cells.” said.

Atasoy added that he has written three international and one national articles on the issue.
