Scientists from Natcore Technology Inc. in the United States and researchers from Rice University in the United States have successfully produced the first inorganic flexible thin film photovoltaic cell.
Using Natcore's patented Liquid Phase Deposition (LPD) process, a cadmium selenide (CdSe) absorber layer has been grown on the rear contact substrate of single-walled carbon nanotubes (SWNTs). Natcore Corporation announced that the CdSe/SWNT layer has exhibited an appropriate photoreaction.
Andrew R. Barron, co-founder of Natcore and professor at Rice University, said that our goal is to create low-cost flexible photovoltaic cells, which marks that we have taken an important step toward the goal.
Photovoltaic test equipment shows a typical IV curve, which confirms that the liquid deposition process may be able to produce flexible photovoltaic cells. Natcore points out that no high-temperature semiconductor process can be used to make this device.
A major milestone leading to low-cost flexible photovoltaic cells
Dennis Flood, chief technology officer and co-founder of Natcore, said that the use of carbon nanotubes is to create a back contact that can be embedded in the absorber layer, and then reduce the diffusion length, which can reduce the percentage of electron-hole recombination, so as to achieve The purpose of improving efficiency.
Chuck Provini, CEO and President of Natcore, said that this is an important milestone on our way to low-cost flexible photovoltaic cells.
"First, we have confirmed this concept. We have demonstrated the feasibility of using liquid deposition."
“Second, if we combine this approach with multi-junction tandem solar cell technology, this will revolutionize the world. Third, this technology should be applicable to the production of roll-to-roll photovoltaic cells. Since we were in the former Kodak This has always been our plan since the establishment of our R&D center near the roll-to-roll optical film factory."
Provini added: “Film products have always faced two major problems: inefficiency and high cost. If this method is integrated with multi-junction tandem solar cells, then we will be able to overcome the above two issues. Our next step is To improve the quality and efficiency of photovoltaic cells, our research and development work will now shift from the laboratory of Dr. Andy Barron of Rice University to the laboratory in Rochester. If we have sufficient funds and sufficient manpower, then we will Within one year, it has a commercial quality battery."
In addition, in October 2012, at the R&D center in Rochester, New York, scientists from Natcore Technology successfully developed the “first black silicon photovoltaic cell†and used the same liquid deposition process. (Compiled by Tao Shuhua)
