Scientists at Johannes Gutenberg University Mainz (JGU) have come out with positive news about increased efficiency of thin-film solar cells. As we know that scientists are trying to increase the efficiency of the solar cells so that they can be considered as serious alternative to the fossil fuels. Researchers at Johannes Gutenberg University Mainz (JGU) too are working at this angle. They opted for the computer simulations to probe deeper into the indium/gallium combination to increase the efficiency of Copper indium gallium (di)selenide (CIGS) thin-film solar cells. Till now CIGS has shown only about 20% efficiency though theoretically they can attain the efficiency levels of 30%. 1 Comment

There has been research work going on to increase the efficiency of the cost-effective amorphous solar panels. TU Delft has been the center where this research work is being developed. The research will directly help in increasing the efficiency of amorphous solar cells - from a 7% to a 9%. Crystalline silicon is most commonly used in silicon solar cells which increases the production cost quite significantly. There is a more economical type of solar panels using amorphous silicon using rather thin films of silicon. The production cost is comparatively less with these panels. 6 Comments

Thermo-photovoltaic (TPV) cells are great for converting radiation from any heat source to power. These cells can generate power from the wasted heat which gets released when glass or steel is produced. Adding these TPV cells to domestic power systems can help generate power along with heating water. TPV systems are also too complex for everyday use. Both of these reasons have made the TPV systems beyond industrial and domestic consumer routine set-up. 3 Comments

The ultimate step in utilizing solar power is to convert maximum energy from sun into electricity. This will make solar power highly cost-advantageous compared to other traditional power sources. Capturing energy wasted as heat from the sun can increase solar conversion efficiency greatly. Research funded by the U.S. Department of Energy is on-going to make this happen. 4 Comments

A new process is being tested by chemical engineers of Purdue University to get high hydrogen production at fuel-cell temperature-level with no catalyst use. This is full of promise for vehicles powered by hydrogen and other portable electronic items like dig-cams, medical diagnostic devices, defibrillators, cell phones and notebook computers. The research funded by US Department of Energy is ushering in a new process. 9 Comments

Yes, the day is not far off when reaching for sky is the new motto for generating cost-effective renewable energy. Initially it was considered to be technically non-viable to tap high-altitude winds. But today, technically-advanced materials and innovative computer know-how are giving new life to this scheme with innovative autonomous aerial structures using wind energy to generate power. 5 Comments

This summer, piloted by Captain Allan Judd, Bullet 580 will usher in the return of inflatable giant airships. The 235 ft long and 65ft diameter ship is covered with a type of Kevlar, a material 10 times-stronger than steel but only one sixteenth of an inch thick. An E-green design special costing £5.5million, this giant runs on algae - latest bio-fuel that can be developed from brackish and waste water. 9 Comments

We love the idea of clean and green fuel. But they come with certain disadvantages. First one is they are heavy on pocket of a commoner. Second disadvantage is their power conversion rate is quite low. Last one is you need storage space to save all the power converted by a clean and green technology. Now MIT researchers are coming out of solar cells printed on paper. Though the technology still has to wait for years before it can be converted into a commercially viable entity but it’s an interesting development. 7 Comments

A research company in New Hampshire recently patented its bladeless wind turbine, which is based on a patent issued to Nikola Tesla in 1913. This wind turbine is christened as the Fuller Wind Turbine. This turbine is developed by Solar Aero. The specialty of Fuller Wind Turbine is it has only one rotating part, known as the turbine-driveshaft. The entire machinery is assembled inside a housing. Wind turbines are often disliked by environmentalists because they kill birds and bats and often generate noise for the residents living nearby. 14 Comments

Fuel cells are clean and green cells. They work without polluting the environment. Fuel cells are electrochemical devices that transform the chemical energy of a fuel into electricity generating water as a by-product. Fuel cells are most used in space flights but they can be best utilized in electric vehicles to reduce air pollution. Fuel powered electric vehicles are better than battery operated EVs as far as efficiency and faster refueling is concerned. 4 Comments

Hydrogen gas is today used primarily for manufacturing chemicals, but a bright future is predicted for it as a vehicle fuel in combination with fuel cells. In order to produce hydrogen gas in a way that is climate neutral, bacteria are added to forestry or household waste, using a method similar to biogas production. One problem with this production method is that hydrogen exchange is low, i.e. the raw materials generate little hydrogen gas. Now, for the first time, researchers have studied a newly discovered bacterium that produces twice as much hydrogen gas as the bacteria currently used. The results show how, when and why the bacterium can perform its excellent work and increase the possibilities of competitive biological production of hydrogen gas. 6 Comments

With the help of photosynthesis plants convert light energy to chemical energy. This chemical energy is stored in the bonds of sugars they use for food. Photosynthesis happens inside a chloroplast. Chloroplasts are considered as the cellular powerhouses that make sugars and impart leaves and algae a green hue. During photosynthesis water is split into oxygen, protons and electrons. When sunrays fall on the leaves and reach the chloroplast, electrons get excited and attain higher energy level. These excited electrons are caught by proteins. The electrons are passed through a series of proteins. These proteins utilize more of the electrons' energy to synthesize sugars until the entire electron's energy is exhausted. 4 Comments

Solar energy is present in abundance around us. The problem is how to harness a substantial portion of it for human use. How to raise the efficiency bar of solar conversion into electricity? Scientists are continuously engaged in finding a way out for this problem. Recently scientists at the Kyoto Institute of Technology have deviated from the normal path and tried to trap the visible as well as invisible rays of sun for electricity. They tried to create a new photovoltaic cell that can capture visible, infrared and ultraviolet light of the sun. The team now thinks that this photovoltaic will be highly efficient for solar power conversion. 6 Comments

Tiny generators developed at the University of Michigan could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor. The energy-harvesting devices, created at U-M's Engineering Research Center for Wireless Integrated Microsystems, are highly efficient at providing renewable electrical power from arbitrary, non-periodic vibrations. This type of vibration is a byproduct of traffic driving on bridges, machinery operating in factories and humans moving their limbs, for example. 6 Comments

With each passing day, scientists are coming out with unique solutions to lessen our dependence on fossil fuels. They are now thinking of turning stray forms of energy such as noise or random vibrations from the environment into useful form of energy. They want to use piezoelectric effect for such purposes. Some materials produce electricity while undergoing mechanical stress. This is known as piezoelectric effect. Small piezoelectric crystals can come up with enough voltage to create a spark which can be utilized to ignite gas. 4 Comments

The researchers of Massachusetts Institute of Technology (MIT) have uncovered a new phenomenon of carbon nanotubes.
