Tech Productivity

We badly need an alternative source of pollution free energy to meet our day to day plus increasing development needs. Mineral oil reserves are estimated to last upto 2020 and coal upto 220 years more. So its not much far and it makes me go mad seeing the petrol and oil prices that would be 2018-2019. How many thousand dollars per barrel ? Leave oil prices, but just think how much pollution it will create. A day without electricity and oil is unimaginable. Though we are going fast in field on alternate sources like solar cells and even mass production of biodiesel, but especially talking about solar energy, it is currently expensive to produce as the metals and special grade silicon used to convert solar energy into electricity is very much less and expensive (silver is used in solar panels). Solar cells have less efficiency in converting solar energy into electricity.

Here is what science daily has come up with an article regarding future scopes of having plastic solar cells having higher efficiency than current solar cells plus cheap (that’s something we badly need). Currently just a research is conducted and results look positive at nanoscale with lots of limitations but they are solving that at nanoscale. But using it for practical means is still a big question. They have tried to raise the efficiency of plastic solar cells to 5.1 % from 3.4 % .
