Discovery could yield more efficient portable electronics, solar cells

Mon, 03/23/2015 - 3:21pm
A team of chemists has set the stage for more efficient and sturdier portable electronic devices and possibly a new generation of solar cells based on organic materials.

Airships: The future of aviation?

Mon, 03/23/2015 - 6:57am
Researchers have completed a three year investigation into stratospheric passenger airships as part of a multi-national engineering project designed to provide a future sustainable air transport network.

Towards 'printed' organic solar cells and LEDs

Wed, 03/18/2015 - 9:08am
Flexible optoelectronic devices that can be produced roll-to-roll -- much like newspapers are printed -- are a highly promising path to cheaper devices such as solar cells and LED lighting panels. Scientists have now created prototype flexible solar cell modules as well as novel silver-based transparent electrodes that outperform currently used materials.

A new method for making perovskite solar cells

Mon, 03/16/2015 - 12:56pm
Researchers have come up with a new way of making thin perovskite films for solar cells. The method forms perovskite crystals at room temperature, which could be helpful in mass production settings. The technique is especially well suited to make ultra-thin, semitransparent films, which could be used in photovoltaic windows.

Scientists move closer to 'two for one deal' on solar cell efficiency

Mon, 03/16/2015 - 12:54pm
The underlying mechanism behind an enigmatic process called 'singlet exciton fission,' which could enable the development of significantly more powerful solar cells, has been identified by scientists in a new study.

Solar could meet California energy demand three to five times over

Mon, 03/16/2015 - 12:51pm
In the face of global climate change, increasing the use of renewable energy resources is one of the most urgent challenges facing the world. New work finds that the amount of energy that could be generated from solar equipment constructed on and around existing infrastructure in California would exceed the state's demand by up to five times.

Uncovering the secrets of super solar power perovskites

Mon, 03/16/2015 - 11:12am
In a scant five years of development, hybrid perovskite solar cells have attained power conversion efficiencies that took decades to achieve with the top-performing conventional materials, but scientists have lacked a clear understanding of the precise goings on at the molecular level. New findings help fill that void.
