Engineers from the University of Nebraska-Lincoln (UNL) and Stanford University show how they created thin-film organic transistors that could operate more than five times faster than previous examples of this experimental technology.
Flexible, transparent thin film transistors for flexible screens.
researchers at the
U.S. Department of Energy's Argonne National Laboratory reported the
creation of the world's thinnest flexible, see-through 2-D thin film transistors.
These transistors are just 10 atomic layers thick—that's about how much your fingernails grow per second.
Transistors are the basis of nearly all electronics. Their two settings—on or off—dictate the 1s and 0s of computer binary
language. Thin film transistors are a particular subset of these that
are typically used in screens and displays. Virtually all flat-screen
TVs and smartphones are made up of thin film transistors today; they
form the basis of both LEDs and LCDs (liquid crystal displays).

The
project involved a collaborative team of researchers at the University
of Illinois and the photovoltaic companies Semprius and Solar Junction.
According to the group’s paper, the module’s top cell consists of a
three-junction (3J) microcell with its own anti-reflective coating to
ensure efficient transmission of light to the uppermost layers. The
bottom cell uses a diffused-junction germanium (Ge) architecture. In a
stacked 3J/Ge assembly, the top 3J cell captures light with wavelengths
between 300 nm and 1,300 nm. Wavelengths from 1,300 nm to 1,700 nm pass
through to the bottom Ge cell with minimal interface reflections, due to
the use of a thin layer of a unique type of chalcogenide glass. - See

“This
is a high-throughput, parallel assembly process that allows for
simultaneous formation of arrays of stacked multi-junction cells in a
fully automated step-and-repeat mode with high yields—greater than 95
percent—and accurate overlay registration. A newly developed interfacial
material for these stacks enables ideal optical, electrical, and
thermal properties. ” stated Xing Sheng, a postdoctoral fellow with

Transparent Solar Cells
MIT researchers are making transparent solar cells that could turn
everyday products such as windows and electronic devices into power
generators—without altering how they look or function today. How? Their
new solar cells absorb only infrared and ultraviolet light. Visible
light passes through the cells unimpeded, so our eyes don’t know they’re
there. Using simple room-temperature methods, the researchers have
deposited coatings of their solar cells on various materials and have
used them to run electronic displays using ambient light. They estimate
that using coated windows in a skyscraper could provide more than a
quarter of the building’s energy needs without changing its look.
They’re now beginning to integrate their solar cells into consumer
products, including mobile device displays. For Read More >>> Click here<<<<

Karlsruhe Institute of Technology (KIT) aims at making organic photovoltaics
The new project coordinated by Karlsruhe Institute of Technology (KIT) aims at making organic photovoltaics competitive to their inorganic counterparts by enhancing the efficiency of organic solar cells, reducing their production costs and increasing their life-time. “Green” processes for materials synthesis and coating play a key role. “MatHero” is funded by the European Commission with an amount of EUR 3.5 million.

Rajasthan Sun Technique 100 MW linear Fresnel project in India
•• It is one of the nearest to completion of
the CSP projects tendered under the 20
GW Indian Solar Mission, which is among
the largest renewable energy policies
passed by an emerging economy in the
last few years. The seven other CSP plants
under the first phase of the Indian Solar
Mission allow for comparative analysis
across different technology specifications
and financing solutions.
•• By awarding subsidized Power Purchase
Agreements through a competitive
reverse auction, the Government of India
was able to deploy CSP plants in a very
cost-effective way. However, it may also
have reduced margins so far that some
winning bidders will ultimately be unable
to build CSP plants.
•• It is highly innovative. It will be the largest ever plant using compact linear Fresnel, a potentially lower cost CSP technology.
•• The project is financed through a combination of private sector resources and development bank funding on non-concessional terms, which is unique for CSP.
