Best of 2011 : Advances in solar panel technology
Solar 3D, a Santa Barbara based technology start-up suite has filed for patents for three dimensional solar cells that could raise energy conversion efficiencies from the current 15 to 18 percent levels to a numeral closer to the 29 percent theoretical limit for silicon. They expect to have a working prototype by the end of 2011.
In conventional silicon photovoltaic panels, some 30 percent of the happening sunlight is reflected back and does not generate electricity. Solar 3D says that it has designed the top surface of its new solar cells with micro grooves that will inveigle accoutrements the sunlight and direct it inwards into the solar cell. This will give the photons more contact time to produce electricity. Solar 3D says the idea is inspired from fiber optics where two concentric layers of bifocals of different refractive indices confine light inside the optic fiber cable.
Solar 3D claims that its new solar panel is being designed for moulding in the same plants that produce current 2D cells. The manufacturing cost will be a major concern following the recent keel over of the solar panel manufacturer, Solyndra which has gone into liquidation after being unsuccessful in competing with low cost Chinese manufacturers.

I have a 6V 50mAH solar cell that I brought from present shack
I tried using it with a small DC motor that takes two AA 1.
Solar cells are typically not meant to immediately drive something. They are meant to charge a battery over an extended period of time, and it is the battery that "drives something".
