rather than the silicon used in conventional solar cells.
A silicon crystal is doped by adding trace amounts of some other element that has either more free
electrons than silicon's four (producing an electron surplus and making the result negative, or n - type) or fewer free electrons (producing a net electron deficit, and hence a positive, or p - type).
For instance, cadmium telluride thin film panels could help solar reach grid parity sooner
than silicon panels could, but tellurium — a key ingredient — is fairly rare.

signals than silicon - based semiconductors can.
Although more
costly than silicon, the material has become central to wireless communications chips in everything from cellphones to satellites, thanks to its high electron mobility, which lets it work at higher frequencies.
Solar cells could be produced from materials other
than silicon under a breakthrough that scientists at the University of California, Los Angeles, say could dramatically reduce the price of solar technologies.
For this, Lieber needed a finer tip — which he found in newly discovered carbon nanotubes, rolled - up carbon sheets that are both thinner and
sturdier than a silicon stylus.
The transistor is about 1,000 times smaller in
area than silicon - based transistors used in electronics today, Levy says.
This year it is held in Sweden with focus on electronic applications of the two - dimensional material with the extraordinary electrical, optical, mechanical and thermal properties that make it a more efficient
choice than silicon in electronic applications.
Because hafnium has a higher k -
value than silicon dioxide, it should be able to do the same or better job at a thickness that prevents leakage.

conductor than silicon.
The hybrid material developed by USC and Northrop Grumman is twenty times better at maintaining temperature
than silicon alone.
The company hopes to double production again this year, taking advantage of automation in the new plant, but it must bring down its sales price, which last summer was two - thirds
higher than silicon module makers» prices, according to analysts.
However, the diversification of this platform into applications other than microcircuits and visible light cameras has been impeded by the difficulty to combine semiconductors other
than silicon with CMOS.
The advance could have enormous implications for electronic devices that incorporate lasers and optical amplifiers, which currently rely on lasing materials that are far more costly and less
common than silicon.
New class of reusable carbon nanotubes could clean polluted waters more
effectively than silicon gels and activated carbon
