It is possible to make a solar cell this way, but it is time-consuming and expensive.
Put a solar cell at the focus of that mirror and you have an inexpensive solar-energy collector.
Solar Junction recently proved out a solar cell with a 44% conversion efficiency.
FORBES: Clean Energy Innovation: An Unstoppable and Volatile Force
The benefit: Rattner could demonstrate a processor doing work while powered by a solar cell the size of a postage stamp .
Take, for example, a team of researchers from Vanderbilt University who developed a solar cell using the photosynthetic protein found in spinach.
Instead of selling individual units, they would offer a low-power system that relied on a solar cell or car battery in remote areas without grid electricity.
HiPerforma is made with a solar cell technology called Pluto, which creates ultra thin copper lines that act as highways to transport the electricity produced by the cells.
FORBES: Suntech's Bid To Outshine Solar Rivals In Cost and Performance
Acting as a lens, the rig's large water-filled orb concentrates diffused daylight or moonlight onto a solar cell with the help of optical tracking to harvest electricity.
Instead of selling individual units, they would offer a low-power system that relied on a solar cell or car battery in remote areas that didn't have grid electricity.
Further, if the basic input to making a solar cell, that Si wafer, has become cheaper then of course we expect the cells themselves, and the panels made from them, to also fall in price.
FORBES: Noahpinion's Two Errors About Free Trade: Yes, Unilateral Free Trade Is The Answer
XsunX, formerly known as Sun River Mining, is now a solar-cell company with no revenue and no orders.
The Moonlight uses energy efficient LED bulbs and is powered by a small solar cell that comes with the lantern.
In related news, the company was also showcasing a couple of other innovations: a new solar cell microchip and its first solar cell.

Intel Chief Technology Officer Justin demonstrated a processor powered by a single solar cell at the Intel Developer Forum in San Francisco Thursday.
The system the researchers tested used a type of solar cell known as dye-sensitized solar cells, a lightweight and inexpensive type where the active layer is composed of titanium dioxide, rather than the silicon used in conventional solar cells.
The all-carbon formula doesn't need to be thickly spread to do its work, and it simply lets visible light through -- it could layer on top of a traditional solar cell to catch many more of the sun's rays.
That is not great compared with the 20% and more achieved by a silicon-based solar cell, the 40% managed by a solar-thermal turbine, or even the 18-20% of one of the new generation of cheap and cheerful thin-film solar cells.
The bankruptcy of a favoured solar-cell manufacturer, Solyndra, was a reminder that governments have a poor record of picking winners in technology, whether green or any other colour.
The other, which faces a specialised type of solar cell made of a material called indium gallium arsenide, is sculpted into a structure called a photonic crystal that causes it to emit infra-red radiation selectively at the frequency best absorbed by the cell.
The total thickness of a completely plastic solar cell is in the range of one micrometer, which is 100 times thinner than a human hair.
And First Solar has a big competitive advantage in solar cell production.
Sharp is also coming out with a sunflower-style solar cell that swivels on two axes to track the sun.
He will then have the option of continuing to use it for nothing, or trading it in for a bigger model, perhaps driven by a 10-watt solar cell.
That mix includes both a solar array and a 5-megawatt biogas fuel cell installation.
Piper Jaffray analyst Jesse Pichel said high prices for polysilicon--a key material used in solar cell manufacturing--eroded LDK's margins.
The UCLA team describes a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent to the human eye.
ENGADGET: UCLA creates transparent solar cell, dreams of current generating windows
But with Apple moving to install giant solar arrays and a fuel cell power station at its iDataCenter in North Carolina as part of an effort to create a coal-free iCloud, Greenpeace on Thursday issued a report that gives a slight upgrade to low marks the group previously gave the company.
Researchers in the solar cell industry have known for a while that one potential avenue for improving solar cells is the use of carbon nanotubes.
He had no human contact, just a cell phone charged by solar power.
