Stanford Makes Nanotechnolgy Solar Breakthrough
Stanford Makes Nanotechnolgy Solar Breakthrough
Chemical engineering Professor Stacey Bent first became interested in a new kind of solar technology two years ago. These solar cells used tiny particles of semiconductors called “quantum dots.” Quantum dot solar cells are cheaper to produce than traditional ones, as they can be made using simple chemical reactions. But despite their promise, they lagged well behind existing solar cells in efficiency.”I wondered if we could use our knowledge of chemistry to improve their efficiency,” Bent said. If she could do that, the reduced cost of these solar cells could lead to mass adoption of the technology. In principle, quantum dot cells can reach much higher efficiency, Bent said, because of a fundamental limitation of traditional solar cells.

India Solar Energy Summit- New Delhi
India Solar Energy Summit- New Delhi
17-18 Feb 2011
I attended this summit as Solar Novus Today representative. Was an action packed conference with some good information sharing and discussions. The networking time interspersed was also quite beneficial. The downside was however that some companies used their speaking slots to merely do a sales pitch rather than sharing knowledge and learning.
Met quite some interesting people in the field of Solar and Renewables in general.
What was striking was that there is a lot happening in India, but there is no central official tracking of facts such as: how much is installed?, what is the performance/learnings? and what is upcoming?. So there was a general feeling in the participants of the summit that there is a lot of proverbial 'darkness' in India in this field. The Ministry of New and Renewable Energy (MNRE) is expected to take some lead in dispelling this darkness.

India’s Readiness as Solar Energy Leader - Solar Novus Today
India is on the right footing but I think far for mature in terms of the value-chain capabilities to get it going. Read my article published in Solar Novus on India's readiness as a Solar leader.
This article needs a bit of Solar know-how in the background esp. the value-chain aspects.

Solar Energy- The most popular demand
Solar Energy has become the most favorable alternative as per a consumer survey done in the United States by Pike Research.
Solar Energy also had the least unfavorable score of only 4%. It also received the smallest percentage of neutral (13%) and not sure/not familiar (4%) type of response. The high levels of very favorable (52%) impressions for solar energy accross gender, income, education and age segments suggests that it enjoys a mass appeal to be the alternative technology of the future. Even older (65 or older) segments of the population had very favorable response to solar energy concept as did the younger segment and that proves that the enthusiasm is prevalent accross all generations. The research also noted that the benefits of solar energy are equally appealing to consumers regardless of their differences in energy consumption, home ownership and adoption of new technologies.
Although this survey only covers US consumers, it is noteworthy as the world's biggest economy acknowledges and embraces the merits of this technology. This acceptance is now widespread and I am sure that other parts of the world would show similar results. Its really opportune that government and organisations of all countries now wake up to this fact and start supporting efforts towards including solar in their key energy mix to ensure security of energy supply and betterment of the environment.
A full copy of the white paper is available for free download on the Pike Research website.

Solar Grandmothers and Postmen of India
Undoubtedly, Solar Power is reaching the heartlands of India in a big way very soon and there are some initiatives such as the two stories below that are really heart-warming on how Solar Power can be also used to eradicate poverty and elevate standard of living in developing countries like India.
Solar Grandmothers
Ever imagined that illiterate and old aged women from remote villages can be recruited as “solar engineers”? The Barefoot College in India trains women from around the world to install and maintain solar lighting and power in their home villages. Using sign language and color-coded circuits, the women learn to build and maintain a variety of solar lamps and chargers in a six months hands-on training course. The Barefoot College "campus" is located in Tilonia, a village in the Rajasthan state of India. The school has trained 150 grandmothers from 28 countries, electrified around 10,000 houses with solar power and saved several thousands of liters of diesel and kerosene from polluting the atmosphere. “There shall now be light, instead of darkness in our village” exclaims one of the ‘graduates’ from the school, who thinks solar energy will replace the polluting and expensive kerosene lamps that she uses now.
The campus itself is a testament to the power of solar energy as everything there is powered by the sun; food is prepared using a parabolic solar cooker, night classes are powered by solar lanterns. "We have shown that solar-electrified villages can be technically and financially self-sufficient," says Sanjit Roy the founder of Barefoot College who is fondly known as “Bunker”. The Barefoot College is an innovative bottom-up approach to rural education and development and is run as a non-profit organization with public donations and government funding.
Solar Postmen
In another story also from the state of Rajasthan in India, post delivery persons (who are mostly men in India) are chosen as beneficiaries of solar powered vehicles. Postmen in India are traditionally looked upon as iconic figures of selfless and friendly social service. They have to walk, trek or ride on bicycle for miles together in the scorching heat or pouring rains in order to deliver letters to homes in the remotest areas. There is often only a single postman delivering letters to the entire village. Their plight will now be alleviated in Ajmer in Rajasthan, which will be the first state in India to deliver postal messages through a solar powered vehicle delivery system.
Sachin Pilot, Union Telecom and IT minister of state, has inaugurated on 24th January 2011 the first solar powered rickshaw for the use of postmen to deliver the postal items. Five eco-friendly solar auto rickshaws were distributed to the postmen in different parts of the district. The state department will monitor the results of this trial and if found worthwhile, it will be spread to other parts of the country. This will certainly broaden the smile on the service-oriented and hardworking postmen of India’s postal service.

Solar Energy Heroes
A list of people I admire in the Solar Energy Sector due to their outstanding contributions. Will keep on adding to this list as and when a new Hero is found!
Harish Hande
Hande co-founded SELCO INDIA (in 1995), a social enterprise, to eradicate poverty by promoting sustainable technologies in rural India. With its headquarters in Bangalore , SELCO has 25 branches in Karnataka and Gujarat. Today SELCO INDIA has installed solar lighting systems in over 120,000 households in the rural areas of these states.
Hande has won the Ashden Award for Sustainable Energy 2005 and Tech Museum Award 2005. Hande has also received the world’s leading green energy award from Prince Charles in 2005. In 2007 SELCO INDIA won the Outstanding Achievement Award from Ashden Awards. The award was presented by Al Gore, former Vice President of the United States of America. Hande was named the Social Entrepreneur of the Year 2007 by the Schwab Foundation for Social Entrepreneurship and the Nand & Jeet Khemka Foundation. He was also the featured attendee and speaker at the Clinton Global Initiative 2007.
In 2008, Hande was chosen by Business Today as one of the 21 young leaders for India’s 21st century. In mid 2008, India Today named him one of the 50 pioneers of change in India.
He was awarded with Asia's prestigious Ramon Magsaysay Award for 2011, also sometimes referred to as Asia's Nobel Prize, for “his pragmatic efforts to put solar power technology in the hands of the poor, through his social enterprise SELCO India”.
Deepak Gadhia
Deepak Gadhia is a manufacturer of Scheffler concentrators and steam cooking systems, parabolic cookers, etc. He engineered and helped create large arrays of Scheffler concentrators for institutions, one of which at Tirupati, India, solar cooks 30,000 meals per day.
Sanjit 'Bunker' Roy
Sanjit 'Bunker' Roy (born 2 August 1945) is an Indian social activist and educator. In 1972 he founded the Barefoot college in Tilonia, Rajasthan. The Indian non-governmental organization was registered as the Social Work and Research Centre. He was selected as one of Time 100, the 100 most influential personalities in the world by TIME Magazine in 2010.
Turning grandmothers into solar engineers is one of Sanjit "Bunker" Roy's favorite jobs. "Solar is the answer".."The way to go about this is not a centralized grid system, which brings in power from hundreds of miles away," he says.
"It is to bring in basic light right down to the level of basic household wherein they take ownership and control over that technology."
Women are the focus for the solar power projects that the Barefoot College runs because men "were very untrainable," says Roy.
