#Adaptive Material Could Cut the Cost of Solar in Half A material with optical properties that change to help it capture more incoming sunlight could cut the cost of solar power in half, according to Glint Photonics,
a startup recently funded by the Advanced Research Projects Agency for Energy (ARPA-E). Glint adaptive material greatly reduces the cost of a tracking system used in some types of solar power.

where a small solar cell is mounted to generate electricity. As the day goes on, the beam of light from the lenses moves and the material adapts,
and reducing the need to keep the apparatus pointed directly at the sun. Glint CEO Peter Kozodoy says solar power from its devices could cost four cents per kilowatt-hour,
compared to eight cents per kilowatt-hour for the best conventional solar panels. This month, the company received the first installments of a $2. 2 million grant from ARPA-E. The ARPA-E funding will allow the company to scale up from prototypes just 2. 5 centimeters across to make 30

#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

#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.
