Scientists get to the heart of fool's gold as a solar material

20-11-2014

As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into electricity. Theoretically, iron pyrite - a cheap compound that makes a common mineral known as ...

Recycling old batteries into solar cells

Proposal could divert a dangerous waste stream while producing low-cost photovoltaics

21-08-2014

This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels that provide emissions-free power. The system is described in a paper in the journal ...

Eco-friendly 'pre-fab nanoparticles' could revolutionize nano manufacturing

UMass Amherst team invents a way to create versatile, water-soluble nano-modules

21-08-2014

A team of materials chemists, polymer scientists, device physicists and others at the University of Massachusetts Amherst report a breakthrough technique for controlling molecular assembly of nanoparticles over multiple length scales that should allow faster, cheaper, more ecologically friendly ...

Taking the lead out of a promising solar cell

Environmentally friendly solar cell pushes forward the 'next big thing in photovoltaics'

06-05-2014

Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using "bench" chemistry -- no fancy equipment or hazardous ...

Breakthrough harnesses light for controlled chemical reaction

Dual-catalyst technique controls 'handedness' of product

28-04-2014

When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants "learned" to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently. In the journal Science, he and three collaborators detail a way to use ...

Organic solar cells more efficient with molecules face-to-face

09-04-2014

New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the ...

Living materials

25-03-2014

Inspired by natural materials such as bone — a matrix of minerals and other substances, including living cells — MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots. These "living materials" combine ...

Bionic plants

18-03-2014

Plants have many valuable functions: They provide food and fuel, release the oxygen that we breathe, and add beauty to our surroundings. Now, a team of MIT researchers wants to make plants even more useful by augmenting them with nanomaterials that could enhance their energy production and give ...
