New solar-cell design based on dots and wires

Using exotic particles called quantum dots as the basis for a photovoltaic cell is not a new idea, but attempts to make such devices have not yet achieved sufficiently high efficiency in converting sunlight to power. A new ...

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 ...

ARM asks Khronos for OpenCL nod for Midgard GPU

(Phys.org) -- ARM wastes no time taking every opportunity to prove its reputation as "GPU computing" kingpins. GPU computing is seen as having a bright future, where the computational performance of the GPU, which was historically ...

Free apps drain smartphone energy on 'advertising modules'

(PhysOrg.com) -- Researchers have shown that popular free smartphone apps spend up to 75 percent of their energy tracking the user's geographical location, sending information about the user to advertisers and downloading ...
