Numerous experiments with different growing conditions have made the researchers wiser to physics behind the formation of the nanowires. A nanowire normally consists of both hexagonal and cubic crystal segments, but the new nanowires only consist of a perfect cubic crystal structure. This means that the path of the electrons through the wire is unaffected and thus suffers less energy loss which leads to a higher efficiency.
- This better understanding of the growing process gives us control over the cultivation of nanowires and the clean wires are the starting point for my current work developing a high efficiency solar cell based on nanowires. With these results we are a good step closer to this goal, explains Peter Krogstrup, pointing out that his nanowires are grown on a silicon substrate.
- The substrate is cheaper than the alternative substrates that many other researchers use. It is important because ultimately it is about getting as much energy as possible for as little cost as possible, explains Peter Krogstrup, whose research is conducted in collaboration with the company SunFlake A/S, which is located at the Nano-Science Center at the University of Copenhagen. The company is working to develop the solar cells of the future based on the nanostructures of Gallium and Arsenic.
- We are very pleased that Peter has delivered such good results so early in the research project, says the CEO of SunFlake A/S Morten Schaldemose.
