Polymer solar cells employing Forster resonance energy transfer

Two crucial tasks exist for realizing high-efficiency polymer solar cells: increasing the range of the spectral absorption of light and efficiently harvesting photo-generated excitons. In this work, Förster resonance energy ...

Manipulating Lorentz and Fano spectral line shapes

(Phys.org) —It is widely known that the optical properties of certain materials can be modified by using lasers to control the quantum states of their optical electrons. Lasers that can generate ultra-short pulses in the ...

New material approach should increase solar cell efficiency

(Phys.org) —A University of Illinois research group brought together aspects of condensed matter physics, semiconductor device engineering, and photochemistry to develop a new form of high-performance solar photocatalyst ...

Ubiquitous Energy sets focus on solar cell technology

(Phys.org)—Can windows, tablets and e readers turn light into power? Can a surface coated with solar cells take sunlight and the glow of bulbs and change them into energy? As reported in Technology Review, expert scientists ...

Cutting light with a comb

(Phys.org)—Quantum physicists from ETH Zurich have discovered special properties in a laser, thanks to which portable devices can be built to analyse gases and liquids accurately and reliably in the future.
