#Sharp Demonstrates Ultra-Efficient Solar cells The best solar cells convert less than one-third of the energy in sunlight into electricity
If it can be commercialized it would double the amount of power a solar cell can generate offering a way to make solar power far more economical.
when sunlight strikes a solar cell it produces some very high-energy electrons but within a few trillionths of a second those electrons shed most of their energy as waste heat.
The Sharp team found a way to extract these electrons before they give up that energy thereby increasing the voltage output of their prototype solar cell.
In theory solar cells that exploit this technique could reach efficiencies over 60 percent. The approach is one of several that could someday break open the solar industry
High-efficiency solar cells would lower the cost of installation which today is often more expensive than the cells themselves.
and figuring out how to make them with high precision (see Capturing More Light with a Single Solar cell and Nanocharging Solar).
which create a shortcut for high-energy electrons to move out of the solar cell. Another way to achieve ultra-high efficiencies now is by stacking up different kinds of solar cells (see Exotic Highly Efficient Solar cells May Soon Get Cheaper)
but doing so is very expensive. Meanwhile MIT researchers are studying the transient behavior of electrons in organic materials to find inexpensive ways to make ultra-efficient solar cells.
Each of the alternative approaches is at an early stage. James Dimmock the senior researchers who developed the new device at Sharp says he expects that his technique will initially be used to help boost the efficiency of conventional devices not to create new ones s
#Elon musk Needs a Very Big Factory for His New Solar technology The Tesla founder and private space entrepreneur Elon musk announced yesterday that Solar City,
And with typical bravado, he also said that the company plans to build a huge factory to produce Silevo high-efficiency solar panels,
a strategy he claims will make solar power ay cheaperthan power from fossil fuels. Solar City is one of the country largest and fastest-growing solar installers,
it will also become a major manufacturer of solar panels, with by far the largest factory in the U s. The acquisition makes sense given that Silevo technology has the potential to reduce the cost of installing solar panels,
Solar City main business. But the decision to build a huge factory in the U s. seems daringspecially given the recent failures of other U s.-based solar manufacturers in the face of competition from Asia.
Silevo produces solar panels that are roughly 15 to 20 percent more efficient than conventional ones.
Silevo isn the only company to produce high-efficiency solar cells. A version made by Panasonic is just as efficient,
and Sunpower makes ones that are significantly more so (see ecord-Breaking Solar cell Points the Way the Cheaper Solar power.
Meanwhile, utilities may start wanting to pay solar-panel owners less for the electricity they produce
because theye increasingly concerned about the intermittency of solar power and the stress this can put on the power grid.

#India's Largest Bank Commits $12. 5 Billion For Renewable energy Funding Private sector project developers in India rapidly growing renewable energy would be happy to have the backing of the country largest bank
The State bank of india (SBI) has committed to provide $12. 5 billion in debt funding to renewable energy projects over the next few years.
The announcement was made at the RE-INVEST summit organised by the Ministry of New and Renewable energy.
The bank hopes to provide debt financing to 15 GW of renewable energy projects most of which are likely to be based on wind and solar energy.
Financing has been a major issue for the renewable energy sector in India. Increased competition in auctions for solar power projects has cut the tariffs by nearly 70%since 2010.
Indian banks are known to question the financial viability of projects secured at seemingly low tariffs. Solar power projects have received especially unfavourable response from the Indian banks as solar photovoltaic power tariffs have been falling
while wind energy tariffs have risen slowly but steadily over the last few years. The lending rates in India are also significantly higher than other countries.
SBI and other national banks usually provide debt at interest rates as high as 11%to 12%.
%Compared to this, development banks like Kfw and US Export-Import Bank and multilateral banks like Asian Development bank and the International finance corporation provide funding at rates as low as 4%.Over the last few years some private banks in India have signed deals with development banks to provide loans
The Indian Renewable energy Development Agency (IREDA) is expected also to provide loans at low rates following its recent agreements with the European Investment bank, Japan International Cooperation Agency,
The renewable energy sector in India has faced collateral damage for years due to the poor financial health of the power sector as a whole.
Unfortunately, renewable energy is considered a sub-sector to the power sector for lending purposes in the Indian banking regime.
As a result, the Indian banks are unable to disburse any fresh funds to renewable energy projects.

#India Plans Association Of Top 50 Solar power Nations Soon after taking oath as India#s 15th Prime minister, Narendra Modi made his renewable energy policy very clear.
His government set an ambitious target to add 100 GW renewable energy capacity by 2022. That is 3 times the current renewable energy installed capacity.
To achieve this target the government organised an investor summit called RE-INVEST. Modi has organised successfully such summits
At this summit the Indian government announced that it will form an association of 50 countries rich in solar energy resource.
India aims to encourage research and development to further reduce costs related to solar power generation. The real motive behind such an association of nations could be entirely different though.
