Butanol can be produced by bacteria in biomass and if an economically efficient method can be found to industrialise that process then your flight of the future could literally be fuelled by alcohol.

One of the solutions to cut down on polluting fuels is the use of wind energy. But the rise in wind farms has unintended its own effects.

Air traffic control systems are being interfered with, both offshore and across moors and hills. The movement of the turbine blades creates, essentially,

Solar panels are able to function because they have intricate patterns of tiny channels engraved into their surface,

high-tech materials now being developed for solar panels. In place of conventional solar panels measuring up to 5 millimetres in thickness,

the modern PV industry is looking to use new types of lightweight and flexible materials to construct solar panels measured in micrometres (thousandths of a millimetre).

With such materials, the scribing process must be controlled with a high degree of accuracy since it is vital that it penetrates only one layer of the thin solar cell film at a time.

PCF lasers provide this accuracy. Moreover, since PCF lasers operate with ultra-short pulse rates,

the flexibility means that solar panels can be wrapped onto any suitable structure, flat or curved. The results of the ALPINE team work, demonstrating the capability of PCF lasers to transform existing scribing technology and opening the way to rapid growth in the high-volume production of flexible,

thin-film solar cells, are hard to overestimate. In the words of Professor Selleri: echanical scribing will disappear very quickly from the PV industry,

#New polymer makes solar cells more efficient Solar cells made from polymers have the potential to be cheap and lightweight

Now a team of researchers led by Yu has identified a new polymer that allows electrical charges to move more easily through the cell boosting electricity production. olymer solar cells have great potential to provide low-cost lightweight

The active regions of such solar cells are composed of a mixture of polymers that give and receive electrons to generate electrical current

when added to a standard polymer-fullerene mixture. ullerene a small carbon molecule is one of the standard materials used in polymer solar cellslu says. asically in polymer solar cells we have a polymer as electron donor

and fullerene as electron acceptor to allow charge separation. n their work the researchers added another polymer into the device resulting in solar cells with two polymers and one fullerene.

when an optimal amount of PID2 was added the highest ever for solar cells made up of two types of polymers with fullerene

The group which includes researchers at the Argonne National Laboratory is now working to push efficiencies toward 10 percent a benchmark necessary for polymer solar cells to be viable for commercial application.

In order for a current to be generated by the solar cell electrons must be transferred from polymer to fullerene within the device.

The fibers serve as a pathway to allow electrons to travel to the electrodes on the sides of the solar cell. t s like you re generating a street

That goal is achievable based on my most recent resultshe researchers also plan to develop a water splitter than runs on electricity produced by solar energy. ydrogen is an ideal fuel for powering vehicles buildings

Renewable energy The batteries could pave the way for renewable energy sources to make up a greater share of the nation energy generation.

Solar panels can only generate power when the sun shining, and wind turbines can only generate power when the wind blows.

#Crystal structure could push the limits of solar cells University of Pennsylvania right Original Studyposted by Evan Lerner-Pennsylvania on November 13 2013 A new model for solar cell construction may ultimately make them less expensive easier to manufacture

and more efficient at harvesting energy from the sun. For solar panels wringing every drop of energy from as many photons as possible is imperative.

As reported in the journal Nature existing solar cells all work in the same fundamental way:

or polarity solar cells need to be made of two materials. Once an excited electron crosses over the interface from the material that absorbs the light to the material that will conduct the current it can't cross back giving it a direction. here's a small category of materials

and of materials science and engineering at the University of Pennsylvania. e call this the bulk photovoltaic effect rather than the interface effect that happens in existing solar cells.

since the 1970s but we don't make solar cells this way because they have only been demonstrated with ultraviolet light

and infrared spectrum. â#Finding a material that exhibits the bulk photovoltaic effect for visible light would greatly simplify solar cell construction.

Moreover it would be a way around an inefficiency intrinsic to interfacial solar cells known as the Shockley-Queisser limit where some of the energy from photons is lost as electrons wait to make the jump from one material to the other. hink of photons coming from the sun

Moreover the ability to tune the final product's bandgap via the percentage of barium nickel niobate adds another potential advantage over interfacial solar cells. he parent's bandgap is in the UV rangesays Jonathan E. Spanier

and close to the desired value for efficient solar energy conversion. o that's a viable material to begin with and the bandgap also proceeds to vary through the visible range as we add more

which is another very useful trait. nother way to get around the inefficiency imposed by the Shockley-Queisser limit in interfacial solar cells is to effectively stack several solar cells with different bandgaps on top of

These multi-junction solar cells have a top layer with a high bandgap which catches the most valuable photons

and cost of the solar cell. he family of materials we've made with the bulk photovoltaic effect goes through the entire solar spectrumrappe says. o we could grow one material

but gently change the composition as we're growing resulting in a single material that performs like a multi-junction solar cell.?
