it can be possible to generate the electricity from the sun with out use of semi conductor plate.?

Question

this is research question because india have genrate more electricity.this is also save the popluation.

Answer 1

Yes, you could use concave mirrors to focus the heat - there's more info at the link

Answer 2

Yes, All photo voltaic cells use semi-conductors so they are not a possible solution.

But a experiment was done back in the 80's where a large collection of computer controlled concave mirrors focused the suns energy on a single water vessel, causing the contents to superheat and generate high pressure steam which could be harnessed to run a turbine and generate electricity.

Answer 3

There is a possible way to generate power from ambient heat.
The method would require some way to access high temperatures,about 700 degrees centigrade,from the ambient temperature,a sort of reverse refrigeration.
The system could work but it would require intensive Rand D, which is expensive. The system would work at night in tropical countries.

Answer 4

Hi:

The answer is yes There are certain plastics and metals that will generate electricity from sunlight. I was watching a show on the Science Channel entitled "2057" which was talking about it. You can check there website about it there. right now photovoltaic cell have not got the efficiency need to be a very good source of energy to replace fossil fuels and other source of energy. but search is on for it.

Answer 5

Semiconductors are the most efficient way to make electricity directly from sunlight, but other materials can work too; they just make way less electricity.

And, as the first answer says, you can use mirrors to concentrate heat onto a boiler to make steam to run a steam engine. That is kind of a clunky, maintenance intensive way to do it, but it can produce a lot of electricity. See the source.

Answer 6

Yes - With the use of a convex lense, heat can be converged and the heat can produce energy and it can be increased. (heat can expand the piston and it can push the wheel and while the wheel start rotating, it works like a dyanamo .... ). Semi-conductor is used only for transformation of energy to our utilization. But it is not going to save population - safety of population is based on many aspects.

Answer 7

Yes, we can. There are things called "solar panels" or "solar cells" that use the power of the sun to generate electricity. Check out the link.

Answer 8

Yea!! it can be possible to make electricity without the use of electricity,because by the theory of photo-electricity if a ray of a particular frequency for a particular element incidents on it the it could excite its electrons to come out of its valence band and generate electricity.But it needs huge amount of that element,needs to state this electric station to be built out of the earth so that it gets rays like COSMIC,X-RAYS to excit its electrons.So it is subjected to unnecessary risk and expence.

SO I SHOULD CONCLUDE THAT IT MAY BE POSSIBLE , BUT WE DONOT NEED TO DO THAT.

Answer 9

Yes. The species that invented the Thermos bottle should be able to use the sun to boil water, providing steam to run a generator.

Answer 10

Of course. Solar power already runs the water cycle, evaporation, condensation, rain, downstream flow. These have and do run generators that make electricity.
