Solar energy

Solar energy refers to the energy derived in form heat and light from solar radiations. This is one of the best renewable energy source provided by nature. It is available abundantly (3.8 million exaJoules).  Solar energy is one of the best forms of alternative energy available to mankind and serves as mitigation for addressing concerns on climate changes, greenhouse emissions and pollution.

Solar technology develops methods by which solar energy can be harnessed into usable forms like power, heat and thermal applications. The applications of solar technology are solar water heaters, traffic lights, solar cookers, power plants catering to smaller community, solar cars to name a few.

Solar technologies will boom in the upcoming years due to the environment green initiatives. In the modern world, solar lighting is preferred way of illuminating large buildings like office spaces, airports and shopping malls. This reduces cost of power and makes the environment sustainable.

Applications with solar technologies will be the future as there will be significant thrust in investments from both the government and corporate sectors. Prices may come down due to new entrants and interest in alternative energy production. One can expect significant breakthrough in research and inventions of solar applications as many countries are already investing on this form of energy.

Metal particle generates new hope for hydrogen energy

Led by Associate Professor Greg Metha, Head of Chemistry, the researchers are exploring how the metal nanoparticles act as highly efficient catalysts in using solar radiation to split water into hydrogen and oxygen. “Efficient and direct production of hydrogen from solar radiation provides a renewable energy source that is the pinnacle of clean energy,” said Associate Professor Greg Metha. “We believe this work will contribute significantly to the global effort to convert solar energy into portable chemical energy.”

Inkjet printing could change the face of solar energy industry

Inkjet printers, a low-cost technology that in recent decades has revolutionized home and small office printing, may soon offer similar benefits for the future of solar energy. Engineers at Oregon State University have discovered a way for the first time to create successful “CIGS” solar devices with inkjet printing, in work that reduces raw material waste by 90 percent and will significantly lower the cost of producing solar energy cells with some very promising compounds.
