One of the most frustrating things about thinking of solar power conceptually is the high cost of manufacturing solar cells.
The good news: There are a growing number of very competent companies manufacturing solar cells for efficient conversion of this sunlight to electricity.
Some green tech ideas, such as the manufacturing of solar cells or lithium-ion batteries, take years to move research out of the labs and into the factories.
The firm also sells imaging and infrared detector products that SunPower makes using its thin-wafer manufacturing process for solar cells.
Bosch said it would unwind the solar power venture and shut down manufacturing ingots, wafers, cells and modules in early 2014.

Embryonic stem cells still face big manufacturing and regulatory hurdles, and have yet to be tested in humans.
Polycrystalline silicon, or polysilicon as it is more commonly known, is the principle component used in the manufacturing of photovoltaic (PV) cells.

Intel and International Business Machines have joined the parade of technology companies making alternative-energy plays, announcing Monday separate efforts to put their manufacturing smarts to work cranking out solar cells.
China is the manufacturing juggernaut that supplies the majority of low-cost solar cells to the rest of the planet.

One of the major benefits of this development is that it only adds a single step to the manufacturing process, meaning that this technique can be adapted to current cells rather rapidly.
Some of the industry giants who announced fuel cells a few years ago swear they are finally on the verge of manufacturing them in quantity.
They are spending hundreds of millions of dollars to build manufacturing plants--giant bio-vats that hold millions of gallons of cultured mammal cells--in order to develop new protein drugs to treat cancer, rheumatoid arthritis and Alzheimer's.
