Solar Cell and photosynthesis; the p680

Bishadi · Jul 7, 2013

I am in a conversation with another and I made a claim of:

Maybe someone read something i wrote 30yrs back and realize that the waveLENGTH is important to comprehend a transfer of energy between any points of time and mass. ie...... at least they are doing science and modeling nature, versus modeling QM

can you post up who the people are that are actually capable of building THAT solar cell?

and i was curious......

keep in mind, that my first paper was the PNC Theory in which, it shares the energy transfer between neurons at the synaptic connection is of a resonant energy transfer (a coherance of light, with the mass), versus the chemical potential exchange that people had been led to believe. Cal Tech responded with, 'per relativity, a photon cannot exceed the speed of light' and dismissed the submission for further review. It is what made me quit the complacent system.

Note the coherance (resonant interaction) within the article.

Photosynthetic organisms, such as plants and some bacteria, have mastered this process: In less than a couple of trillionths of a second, 95 percent of the sunlight they absorb is whisked away to drive the metabolic reactions that provide them with energy. The efficiency of photovoltaic cells currently on the market is around 20 percent. What hidden mechanism does nature use to transfer energy so efficiently?

Various research groups around the world have shown that this highly efficient energy transport is connected to a quantum-mechanical phenomenon. However, until now, no one had directly observed the possible impacts of such a quantum transport mechanism at work at room temperature.

In an article published in the journal Science, researchers from ICFO- Institute of Photonic Sciences, in collaboration with biochemists from the University of Glasgow, have been able to show for the first time at ambient conditions that the quantum mechanisms of energy transfer make phyotosynthesis more robust in the face of environmental influences. The quantum phenomenon responsible, known as coherence, is manifested in so-called photosynthetic antenna proteins that are responsible for absorption of sunlight and energy transport to the photochemical reaction centers of photosynthesis.

In order to observe quantum effects in photosynthesis, the research group led by Niek van Hulst developed a pioneering experimental technique. Energy transport during photosynthesis is extremely fast and takes place at a molecular scale. To observe these processes they pushed the ultrafast spectroscopy techniques to the single-molecule limit. This involves sending ultrafast femtosecond light flashes to capture a high-speed series of 'pictures' of the states of individual antenna proteins after light absorption (during one femtosecond light travels only one hundredth of the diameter of a human hair, while in one second it travels from earth to moon). With these "snapshots" the researchers are able to understand how solar energy is transported through single proteins. "We have been able to observe how energy flows through sunlight absorbing photosynthetic systems with unprecedented spatial and temporal resolution. This allowed us to observe the fundamental role of quantum effects in photosynthesis at ambient conditions" explains Richard Hildner, first author of the publication.

Van Hulst and his group have evaluated the energy transport pathways of separate individual but chemically identical, antenna proteins, and have shown that each protein uses a distinct pathway. The most surprising discovery was that the transport paths within single proteins can vary over time due to changes in the environmental conditions, apparently adapting for optimal efficiency. "These results show that coherence, a genuine quantum effect of superposition of states, is responsible for maintaining high levels of transport efficiency in biological systems, even while they adapt their energy transport pathways due to environmental influences" says van Hulst.

The results presented raise fascinating questions. Was the exploitation of quantum effects in photosynthesis driven by evolution to achieve the extraordinary efficiencies, or in other words did quantum transport outcompete other mechanisms during evolution? Are there other biological processes in which quantum effects play an important role? In the case of light-harvesting proteins quantum transportation allows extreme transport energy efficiency and robustness. This discovery could lead to new research lines aiming at the developments of a new generation of solar cells that mimic these quantum coherences for efficient energy transfer

I am bridging the concepts for any to see for themselves.

there is a paper to read.

and site

tinkerers are the ones to watch

On that paper notice the 'antena' is a 'field' of specific size for the matter.

Real world application will always smoke the complacent!

That was not the comment; it was per relativity a photon cannot be slowed

ie.... held upon mass

Although, i will point out that t<0 of a predetermined outcome.
