#New technique helps probe performance of organic solar cell materials A research team led by North carolina State university has developed a new technique for determining the role that a material's structure has on the efficiency of organic solar cells

There have been a lot of studies looking at the efficiency of organic solar cells but the energy conversion process involves multiple steps

Broadly speaking organic solar cells convert light into electric current in four steps. First the cell absorbs sunlight which excites electrons in the active layer of the cell.

In previous organic solar cell research there was ambiguity about whether differences in efficiency were due to dissociation or charge collection#because there was no clear method for distinguishing between the two.

so that it runs parallel to the long axis of organic solar cell molecules it will be absorbed; but if the light runs perpendicular to the molecules it passes right through it.

The researchers created highly organized nanostructures within a portion of the active layer of an organic solar cell meaning that the molecules in that portion all ran the same way.

and nanostructure features are needed to advance organic solar cell technology. Explore further: Hybrid materials could smash the solar efficiency ceiling More information:

#Researchers create novel nanobowl optical concentrator for organic solar cell Geometrical light trapping is a simple and promising strategy to largely improve the optical absorption and efficiency of solar cells.

The novel nanobowl optical concentrator developed by Professor Zhiyong Fan can largely enhance the optical absorption in the active layer of organic solar cell

the researchers tested a number of molecules that are used also within organic solar cell research at Chalmers.

or discontinuous pathways that pose a serious drawback when using blended systems known as bulk heterojunction donor-acceptor or positive-negative (p-n) junctions for harvesting energy in organic solar cells.

He says This work is a major advancement in the field of organic solar cells because we have developed

For decades scientists and engineers have placed great effort in trying to control the morphology of p-n junction interfaces in organic solar cells.

and are therefore highly suitable for use as the absorber layer in organic solar cells. Compared to normal graphene

Doctoral student and first author Tim Gehan says that organic solar cells made in this way can be semitransparent as well so you could replace tinted windows in a skyscraper

and directly used the transparent electrodes for organic solar cells. The research outcome was introduced in Nanoscale a journal of Royal Society of Chemistry in the UK under the title of One-step Synthesis of Carbon Nanosheets Converted from a Polycylic Compound

and Their Direct Use as Transparent Electrodes of ITO-free Organic solar cells and was selected as a cover story in the January 21st edition in recognition for this innovative and superb research findings.

#Australian scientists develop 3d printed organic solar cells capable of powering a skyscraper It no secret that solar panels are set to change the way the world harnesses energy-especially

organic printable solar panels as part of the Victorian Organic solar cell Consortium. According to the researchers, the printable panels are capable of powering entire skyscrapers

and farther--aiding the hunt for flexible electronics, organic solar cells, and other low-cost alternatives to silicon.

#Shortening Organic solar cell Production One of the building blocks of the solar panel, solar cells are responsible for converting solar energy into electricity.

Now, the U s. Dept of energy (DOE) Oak ridge National Laboratory (ORNL) has developed a method to save steps in the organic solar cell manufacturing process by introducing solvents into solar cell film production.

However, the information obtained from the neutron reflectometry will help scientists boost organic solar cell performance, according to ORNL. ptimization of photovoltaic properties provides information to manufacture solar cells with fully controlled morphology

Hybrid, semi-organic solar cells are still being developed and perfected at the research centers all over the world. KTU and Swiss Federal Institute of technology Lausanne have registered the invention at the European Patent office. e concluded, n V886,

University of Melbourne researchers say their discovery of the highly sought-after'nematic liquid crystals'can now lead to vastly improved organic solar cell performance.

"The discovery is a step forward for the wider commercialization of printed organic solar cells. But more than this, could aid in the development of new materials with improved performance such as LCD screens."

"Uptake of the current generation of organic solar cells has lagged behind more widespread silicon-based models, due to their comparative lack of performance even with a simplified construction via large printers.

Published July 20 in the journal Nature Communications, the study showed that constructing a type of organic solar cell on a on-wettingplastic surface made it 1. 5 times more efficient at converting sunlight to electricity.
