Solar double the assembly will be cheaper
One of the most pleasant news in the field of alternative energy, are considered to be either improved performance or lower prices for the final product. In this case, an opportunity to highlight the second of the above events. However, the fall in price is not the most ordinary devices.
What influenced the decline in prices for & laquo; double & raquo; solar panels?
solar panels one above the other, you can improve overall sensitivity to the perception of the different types of photon energy. As a result, a wider range of processed into solar electricity than increases the overall efficiency. Previously, the creation of such a & laquo; tandem & raquo; It required a lot of effort:
- The complex process;
- Extremely pure monocrystalline cell;
- Costly production.
As a result the scope of application was very low, the bulk of the double photocell involved in space programs. A recent breakthrough of Swiss scientists from the Laboratory of Materials Science & laquo; EMPA & raquo ;, announced only a few days ago. Tandem Panel failed to make of polycrystalline materials. They, in turn, can be applied to a thin metal foil or like items on a flexible plastic film.
Another achievement was the way to producing perovskite layer at a sufficiently low temperature of + 50C, which means cost savings in the production process. Efficacy perovskite reached 14.2%, and its transparency level was quite high 72%. The resulting annealed nanocrystalline layer perovskite took great yellow and blue spectrum, but passed through a infrared and red rays. They fell to the second cell, so efficiency was maximum.
Made engineers & laquo; Empa & raquo; prototype gave an efficiency of at least 20.5%, which was quite close to the single-layer polycrystalline battery of a new generation of 25%. The scientists hinted that it is only the first steps, because in the long term strap technology can cross 30% figure.
Operation with uninterruptible power supply
UPS uninterruptible power supply when dealing with a new type of & laquo; double & raquo; photo panels will not feel. Therefore, the market does not have to be reconstructed bespereboynik or issue additional hybrid converters. The truth is the effect of the expansion of alternative energy, competition in the field of hybrid devices could jump considerably.
