#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

#Stronger better solar cells: Graphene research on the cusp of new energy capabilities (Phys. org) There remains a lot to learn on the frontiers of solar power research particularly
when it comes to new advanced materials which could change how we harness energy. Under the guidance of Canada Research Chair in Materials science with Synchrotron radiation Dr. Alexander Moewes University of Saskatchewan researcher Adrian Hunt spent his Phd investigating graphene oxide a cutting-edge material that he hopes will shape the future
All of this makes graphene a great candidate for solar cells. In particular its transparency and conductivity mean that it solves two problems of solar cells:
first light needs a good conductor in order to get converted into usable energy; secondly the cell also has to be transparent for light to get through.
Most solar cells on the market use indium tin oxide with a nonconductive glass protective layer to meet their needs.
It's the factor that will keep solar cells expensive in the future whereas graphene could be very cheap.
Although graphene is a great conductor it is not very good at collecting the electrical current produced inside the solar cell
Whether or not it will solve the solar panel problem is yet to be seen and researchers in the field are building up their understanding of how the new material works.
It's a pitfall that could be important to understand in the development of long-lasting solar cells where sun could provide risky heat into the equation.
More research like this will be the key to harnessing graphene for solar power as Hunt explains.
"One application the group is now exploring is a thin film solar cell, made of densely packed nanowires,
that could harvest energy from light much more efficiently than traditional thin-film solar cells s
In this case the microwave-harvesting metamaterial that acts kind of like a solar panel converting microwaves into up to 7. 3 volts of electricity enough to charge small electronics.
although digital cameras and solar panels have different purposes-one measures light while the other converts light to power-both are constructed from essentially the same components.
The same photodiode is used also in solar panels to convert incident light to electric power. The photodiode in a camera pixel is used in the photoconductive mode
while in a solar cell it is used in the photovoltaic model. Nayar, working with research engineer Daniel Sims BS'14 and consultant Mikhail Fridberg of ADSP Consulting, used off-the-shelf components to fabricate an image sensor with 30x40 pixels.

It uses something called HCPVT (Highly Efficient Concentrated Photovoltaic/Thermal) to generate electricity and hot water from solar power.
as well as highly efficient photovoltaic cells (known as gallium arsenide photovoltaic cells) to convert that concentrated solar energy into electricity. Though concentrated solar thermal power
and PVS are nothing new to the solar power industry, the Solar Sunflower incorporates these technologies in a novel way that represents a few ingenious engineering breakthroughs.
"In other words, the difference between this technology being classified as a death ray as opposed to a solar array is merely a matter of how the reflectors are angled.
Photovoltaic cells used by the Sunflower have a max operating temperature of around 105 degrees Celsius,
Its gallium arsenide photovoltaic cells though more efficient than standard PV cells, are not cheap. Add up construction costs and the costs of the fancy cooling system,
and the design isn't going to be able to financially compete with less innovative but sure-fire solar energy harvesters already on the market.
