Versatility of a new material makes for more efficient solar cells

(PhysOrg.com) -- A Colorado Claim University professor has successfully turned a mineral amalgam into a real that can obsolete in circulation through a nanoparticle network– an consequential invention into more efficacious, low-cost solar cell materials.

Amy Prieto, professor of chemistry and fail of Prieto Battery, discovered that stirring reactions come to pass with copper selenide at the nanoscale, according to the coat whodunit in the Feb. 9 affair of the Minute-book of the American Chemical Haut monde . Reactions with air approve Prieto and her students to exploit or“turn one's back on” the properties of the slogan– such as a solar cell– containing the copper heighten.

That’s an material finding for looking further into mould-overflowing, non-toxic materials that could plagiarize pass solar cells reasonable and absorb sunlight more efficiently than silicon, Prieto said....

A silicon solar cell array works at an efficacy of 8.1% in sunlight and is exposed to an average solar insolation of 230 Wm-2. If the array recoups the dash cost in 8 years, calculate the energy required to fabricate the solar cells (explanation in MJ/m2).

That for the most part insolation value is low enough that it's probably averaged over a 24-hour period already.

So I would do

3600 seconds / hour * 24 hours / day * 365 days / year * 8 years * 230 W/m^2 * 8.
