Posted February 17, 2020 07:04:10A new research paper from the University of California, Berkeley, provides the first scientific evidence for a carbon atom’s role in solar cells.
The research is the result of a collaboration between the University and researchers at Stanford University and the University at Buffalo.
In a paper published in the journal Science Advances, UC Berkeley researchers describe how they used high-resolution X-ray spectroscopy to study how the electrons in a single carbon atom interact with the hydrogen and oxygen atoms in the solar cell.
By using a computer program, they were able to determine the properties of the carbon atom and its structure, such as its hydrogen and carbonate structure.
They used the same X-rays to measure the electrons’ position in a cell of a solar cell that was made up of two layers of carbon and one silicon.
The carbon atoms had a carbonate lattice.
The silicon layer has a double layer of carbon atoms.
The researchers say the carbon atoms’ position and size is determined by their position and location in the two layers, and by the lattice’s position relative to the other layers.
They found that the position of the electrons and the lattices were determined by the two lattice dimensions, not the latticework.
The result, the researchers say, suggests that the electrons of the solar cells in the study were not only able to change the electron configuration of the silicon layer, but also the latticity of the structure.
“We found that carbon atoms are a very powerful control for the lattine configuration of a silicon layer,” said Jens Schönbrink, a UC Berkeley professor of electrical engineering and computer science and a co-author of the paper.
The research was part of the UC Berkeley Center for Advanced Solar Energy (CASE) project, which has identified more than 2,000 possible photovoltaic materials.
It was funded by a National Science Foundation (NSF) grant, which is called the Advanced Photovoltaics (AP) Initiative.
The paper is titled “Experimental identification of the electron and lattice configurations of carbon nanotubes and silicon nanowires in solar cell materials.”
The research, published in ACS Applied Materials & Interfaces, was led by co-authors Rong Li and Yong Li.
