The research in organic semiconductors have provided a vital break through in the field of electronics.So , why cant we extend this new field to meet our ever rising demand for energy?

not for now, their efficiency is too low.
From the same surface you gain only 1/7 or 1/6 of the electricity gained from a common Si based photovoltaic panel.
We need to do much more research and develop better organic semiconductors.
However organic based semiconductors are really cheap if mass produced respect to the production of electronic grade Silica.
So yes, i'm looking forward in a near future to cover every roof, tent,house, car and every flat surface with organic solar panels.

It is possible to fullfill our energy needs by solar cells if we can place these solar cells in high orbits(in space) where it gets undiluted solar energy and that also for almost 24 hours.In fact, this will produce much more energy than our need.
But the challenges are:
(1) how effectively we can transfer this high energy back to earth?
(2) The solar cells must be very advanced -- should be self repairing -- thus not needing manual human intervention frequently, which is very costly.
I think other viable options like cold fution e.t.c must also be researched without expecting any immediate result from them.

Even with the advances in these cells our industrial consumption is much larger than the offset these cells can provide. For instance, I recently investigated the use of these cells at my facility to offset our electricity demand from the utility. I would have had to put in 4 acres of these cells to offset my annual demand by 2%.
Even on the average home it would still require a significant amount of cell area to provide a cost/benefit ratio that is acceptable. That is why the some states are subsidizing the capital costs.
The other part of the puzzle is they have a limited lifespan, the output degrades over time, and they require external equipment to convert their output to AC.

In order to fill this you must be able to understand the reason for the void in energy problem. Although there are some theory on how to solve this. Scientist just can't manipulate the tools we have now enough to solve the problem and by using semiconductors we can fill some of this void but the problem is not that we don't have a big enough fuel supply. It's that we don't have the meens to get this energy caputered.I think we can fix this but it will take one good person to do it and many hard years to fix it. And eventhough the problem is getting bigger by the day it's not impossible to fix.

very few clarifications. The equivalent area for a plant to furnish all US electric powered power needs is about a sq. one hundred miles on a aspect, it is 10,000 sq. miles. I look to bear in mind 100 and twenty miles on a aspect, yet assume efficiencies have lengthy gone up. In practice, there does no longer be a unmarried plant that tremendous, for sure, there will be many smaller vegetation. Silicon is between the most substantial aspects in the earth's crust - there is not any longer a controversy of looking sufficient of it. the cost will be tremendous, yet no longer 1000's of trillions of money. perhaps 5-10 trillion, the size of the nationwide debt. nonetheless tremendous. be conscious that importing oil weakens our forex, circuitously contributing to the nationwide debt. i trust nuclear (fission) has its position, through the way, alongside with the different technologies listed above. Fusion and antimatter are nonetheless some distance from commercialization. you're actual about hydrogen in words of power performance, yet that would not advise that it should not be used as an power storage medium. a chargeable battery continually returns decrease than grow to be placed into it, yet such batteries are fairly functional. Oil itself has an performance of decrease than a million, pondering the picture voltaic power first placed into turning out to be the prehistoric vegetation that went into it. probably, if we use hydrogen, it may well be as a conveyable gasoline, and the flexibility to make that hydrogen ought to come from renewable resources.

well the answer lies in your question.
since they are organic u can consume them and i think if u take them with water they would satisfy your thirst for energy.
water quenches thirst and organic stuff's digestion gives u energy..

We can and we are..I for one truly believe that these solar energy
can fulfil our needs by far.
