Course: Solar PV Feasibility Assessment - Green Africa Directory. New organic solar cells process sunlight as plants do. Considering that green plants have been converting sunlight into sugar for millions of years, it's only natural that scientists would look to them as a model for improving solar energy technology.
Scientists recently developed an organic substitute that processes sunlight as a plant does. Advancing this technology could aid the evolution of solar power as a sustainable energy strategy. Most traditional solar cells are made of glass or plastic, which makes them breakable and hard to recycle. In order to address these problems, researchers at the Georgia Tech College of Engineering experimented with organic compounds made from wood. The compounds, dubbed cellulose nanomaterials (CNs), are very thin and come from trees (a renewable resource). CNs — a fancy way of saying "miniscule plant parts" — achieve reasonable solar efficiency and lend themselves to cheap production on a mass scale. While CNs solve the problem of sustainability neatly, efficiency is still a major issue. Whyburn_Gordon. Solar Cells Lecture 5: Organic Photovoltaics. Photochemical carbon dioxide reduction. Photochemical carbon dioxide reduction harnesses solar energy to convert CO2 into higher-energy products.
The chemical conversion of CO2 already occurs on an industrial scale in the manufacture of solvents such as formic acid, but photochemical reduction differs in that it relies on a renewable energy source, the sun. Because CO2 is a greenhouse gas, there is environmental interest in producing artificial systems that are efficient photocatalysts, but the low turn-over rates of current methods have prohibited wide-scale industrial application. Overview[edit] [1] Molecular sensitizers that meet this criterion often include a metal center, as the d-orbital splitting in organometallic species often falls within the energy range of far-UV and visible light.
The reduction process begins with excitation of the photosensitizer, as mentioned. An example of photoexcitation using Ru(bpy)3 and triethylamine. An example of a supramolecular complex capable of photochemical reduction. History[edit] Solar Energy A Boon For Power-Thirsty Off-Grid Africa. In off-the-grid Africa, energy poverty is endemic and with national grid expansion lagging far behind market demand, Africans are looking to solar for innovative, affordable solutions for lighting and charging mobile devices, says Fortune in an in-depth story about how small, tech savvy companies are beginning to capitalize on Africa’s power needs.
Author Keith Proctor talks about how people use car batteries to charge mobile phones and kerosene is the most common source of lighting, despite its danger and polluting capacity. Solar is still a complementary source in the continent’s energy mix but the growth it’s experienced shows how the region is shifting towards renewable energy, he says. From $750 million in 2004, the solar market in Africa will grow to $57 billion by 2020, according to the U.N. The driving need for innovative solutions has attracted savvy but small players such as Fenix International to the African market. Following the advice of the late management guru C.K.

General information Overall description. Talking Small Biz: A Philly nonprofit's energy for Africa. Q: So what happened next?
A: We set up a nonprofit with a board and got incredible support. I believe the success came from working directly with people in Gambia and the stories we had to tell were so powerful. Solar non-profits in Africa. Have light, will shine!
In the country of Uganda, with 35 million people, 95% of the rural population still lives without electricity. They are living in energy poverty– along with 1.6 billion other poor people, or ¼ of the world’s population. Electricity is fundamental to development, for without it women and men can’t see to work, children can’t see to study, midwives can’t see to deliver babies, and economic growth is virtually impossible. Kerosene and candles offer a dim alternative: smoky, dangerous fuel that eats up to 30% of a family’s income and offers precious little light–particularly for women and girls, who are primarily responsible for cooking, heating and lighting the home. These statistics really bothered Katherine Lucey, a former New York investment banker with an expertise in the energy sector, who’d turned her attention to finding solutions for the energy poverty that plagues the developing world.
