Eco Trees

Two teams of scientists have accomplished methods to produce nanowires that could greatly improve the solar photovoltaic cell efficiency. The first technique used by researchers from UC San Diego creates' hairy 'solar cells, which are visible only through the microscope. In conclusion, the hairs are the nanowires, silicon or tiny metallic structures used to complete very small circuits.
Onto a cheap conductive surface, the researchers were able to grow nanowires which are coated with an organic polymer.

And finally, the second team consists with researchers from the three Germany universities have created a technique to bond with nanowires spun glass. This technique is based on a kind of high-tech 'sandwich'. By this way the nanowires are placed between a metal layer and a highly conductive bottom layer and then on a glass forming a 'spacer layer' to prevent the circuit from shorting. The current could lead to a completely new class of efficient integrated circuits and an run smoothly along the nanowires.

However there are some problems to the San Diego team because when it is exposed to air the polymer layer currently degrades. If either of these two techniques will work and will be put to commercial scale, installation of solar panels will be more cheap and easy to mount. In my opinion this is the future for solar panels.
