Tech News 1: A bright future: Seeking a third generation of better-performing solar cells

[bob_turner]

For a greener and more sustainable economy, building better and more powerful solar cells is a key research goal within the clean energy sector. But, in a typical single-junction solar cell, performance is capped at what is called the Shockley–Queisser limit (a theoretical limit for the maximum efficiency that a solar cell can reach). Efficiency determines how much of the light energy (photons) absorbed by the solar cell can be converted into usable electric current. The Shockley–Queisser limit...
