1, The cars' electric motors are energized by solar cells.

2, By contrast, solar cells are politically acceptable.

3, But solar cells are constantly improving, experts say.

4, Conventional solar cells rely on silicon crystals, and energy conversion is around 10 percent.

5, These modular construction kits now include solar cells, rechargeable batteries etc.

6, Alternatively, arrays of solar cells may be made on the Moon out of lunar materials and only the power exported.

7, In solid-state solar cells the junction between two materials of different electronic properties absorbs light and converts it into electricity.

8, Cheaper solar cell AMERICAN scientists have doubled the efficiency of liquid-junction solar cells.

9, A solar cell panel repays the electric power needed to manufacture it in its first few hours of operation.

10, This will cut the cost of solar cells by more than half,(sentencedict.com) and increase their ability to convert light to electricity.

11, Thin-film amorphous-silicon solar cells may be manufactured to expand the electrical power supply to the base.

12, Note that the solar cell has an efficiency of only about 10%.

13, This type of solar cell is now a possible alternative to its solid-state counterpart.

14, The biggest single drawback of solar cells, then, is the need for storing two weeks' worth of power.

15, A solar cell is rechargeable by itself.

16, The soldier took out a solar cell.

17, A solar cell is reproductive by itself under any circumstances.

18, A typical untreated silicon solar cell absorbs just over two thirds of the sunlight it receives.

19, Compared to the bipyridine ruthenium solar cell,(http://sentencedict.com/solar cell.html) the new prepared solar cell shows very good properties by testing its I/V curve.

20, He is planning another trip into the countryside to demonstrate his solar cells as well as a new solar cooker.

21, The company says the process could sidestep some of the problems of conventional solar cells, such as cost and low efficiency.

22, The concept is essentially one of replacing expensive solar collectors and solar cells with tree leaves.

23, Research on solar-cell design has recently shown us how to make extremely lightweight solar cells.

24, However the problem of low efficient of photo - electricity transfer monocrystalline silicon solar cell.

25, China accounted for about a third of the market for global solar cell production in 2008 while Europe's share declined to about a quarter, according to a survey by German industry publication Photon.

26, Finally, based on the simulated cell parameters, we designed a new SSP polycrystalline silicon thin film solar cell, and the specific process of the implementation process were discussed.

27, This paper introduces the 39th IPhO experiment test, which using the differential thermometer to measure the solidifying point of a crystalline solid substance and an efficiency of the solar cell.

28, CIGS film absorber layer , which plays crucial role in enhancing the conversion efficiency of solar cell.

29, The special structure design and the presence of RTV grouting between the solar cell strings can prevent the secondary discharge incidents efficiently.

30, Boron is one of acceptor elements in polycrystalline silicon solar cells, which can influence the photo voltaic efficiency and stability of a solar cell.
