Solcelle-forbedring egnet til Danmark:
University of California, Merced (2012, January 19). Researchers' refinement increases solar concentrator efficiency. ScienceDaily:
http://www.sciencedaily.com/re....htm
Citat: "...
A team of researchers at the University of California, Merced, has redesigned luminescent solar concentrators to be more efficient at sending sunlight to solar cells.
...
The hollow cylinders absorb more sunlight while having lower self-absorption losses.
...
Luminiscent solar concentrators are designed to absorb solar radiation over a broad range of colors and re-emit it over a narrower range (for example, only red), a process known as down-converting. This light is transported to solar cells for photocurrent generation. The quantum dots embedded in the concentrator are the materials that carry out this color conversion.
...
The biggest advantage they offer over traditional solar cells is that they can work even in diffuse sunlight, like on cloudy days. And because of this, they do not need to directly face the sun at all times, eliminating the need for tracking mechanisms.

University at Buffalo (2012, January 20). In solar cells, tweaking the tiniest of parts yields big jump in efficiency. ScienceDaily:
http://www.sciencedaily.com/re....htm
Citat: "...
With military colleagues, the UB researchers have shown that embedding charged quantum dots into photovoltaic cells can improve electrical output by enabling the cells to harvest infrared light, and by increasing the lifetime of photoelectrons.
...
The UB researchers and their colleagues have not only successfully used embedded quantum dots to harvest infrared light; they have taken the technology a step further, employing selective doping so that quantum dots within the solar cell have a significant built-in charge.
...
The technology has the potential to increase the efficiency of solar cells up to 45 percent, said Mitin, a SUNY Distinguished Professor.
