Dutch Scientists Developing Sixty Five Percent Efficient Nanowire Solar Cells

By Esther Alarcon

High efficiency solar cells tend to be for this time only available to space uses, on account of their particular prohibitive costs. The Eindhoven University of Technology from The Netherlands, with a EUR 1.2 million help from the Dutch administration desires to develop super-effective solar cells which are also inexpensive. These people visualize their particular cells having a sixty five percent efficiency, something even the satellites might envy.

Presently, thin film solar cells have an effectiveness somewhere about forty percent. Recent studies as well as prototypes made with concentrated solar panels disclosed a conversion of 41 percent, though the researchers coming from TU/ want more. They will use mirror systems which concentrate the particular light one thousand times and make use of hardly any substance for the actual solar cells, which would be very expensive usually if used at complete level.

Jos Haverkort, one of the scientists, said: “If the Netherlands desires to timely take part in a commercial exploitation of nanowire solar cells, there is a good urgency to jump in now.” The research is conducted together with Philips MiPlaza.

Their concept concerning how to make their fantasy feasible relies on stacking a lot of subcells(junctions) in each and every cell, by which each subcell has to transform a specific spectrum of light optimally into electrical power. The best nanowire solar cell made to this day has an 8.4 percent performance. The Dutch research workers wish to encase the nanowires inside safety shells in order to obtain the exact same high performance just like slim-film cells. Haverkort believes that 5 to 10 junctions will be enough to improve the solar cell getting the desired sixty five percent efficiency.

Production expenses are additionally cut by their proposed technology, because the nanowires which make their solar cells can be grown on cheap silicon substrate as well as grow more quickly. Gallium together with Indium, the 2 expensive and rare materials that they will utilize for the tiny solar cells are going to be used very scarcely.

Not too long ago, the price tag on solar cells was at approximately $3/watt. Now it is almost $2/watt (even less). Right after the particular researchers coming from Eindhoven will have finished their particular work plus the market will have happily approved their solar cells, the price should drop lower than 50 cents per watt, which sounds extraordinary. We will wait and we will see.

In case you really care about your future, be eco friendly. We all could accomplish this by choosing eco friendly products and engaging in environment friendly pursuits. We only have one world to exist in so we should stand up for this!
