I've read 10% efficiency is the goal, but are how confident are you in getting that with the current setup? Is 20%, 30%, 90% possible?

The current record for organic solar cells is 5.6%, so clearly a jump to 10% will be revolutionary, and make plastic solar cells commercially viable. Commercial plastic solar cells today struggle to reach 3-5%.
But I imagine that the researchers dream about finding a game-changing 15-30% efficient material. This will be better (as well as vastly cheaper) than conventional silicon cells, and will even be competitive against the newest and most expensive experimental solar cell technologies. We can dream, can't we? |

Thank you. So fingers crossed!
Also, I've been reading the Faq, but not really sure about the science. Can someone explain how the temperature and Energy/mol affects the cell? For example, one work unit I have is currently displaying Energy at 4448 kcal/mole and 214 Kelvin. The other is at 4621 kcal/mole and 517 Kelvin (which is 200+C?). What are the researchers looking for there? High energy I am guessing and low temperature? And if high energy, how high does it need to be to hit the magic 10% efficiency? |

I noticed this gap in the information, too.
Probably it is the kind of thing that is obvious to a molecular chemist - but not to me! Researchers: http://www.worldcommunitygrid.org/projects_sh...Faq.do?shortName=cep1#386 does not actually answer the question. Please will you expand it? |

What are the researchers looking for there? High energy I am guessing and low temperature? ajpr: Right now we are not explicitly looking at the interaction of sunlight with the material (in this case, a cluster of molecules). Therefore at present, there is no direct relation between efficiency, temperature and energy. Presently, we have calculations that do a temperature sweep. Naturally there will be an energy associated at each temperature. We are doing a broad sweep to obtain enough data that will be of interest to those who will develop and fabricate organic solar cells. However there is a set of parameters, such as packing of the molecules, total energy and other various quantum mechanical properties that will lead us to identify if a specific material could have good solar cell efficiency. Researchers: http://www.worldcommunitygrid.org/projects_sh...Faq.do?shortName=cep1#386 does not actually answer the question. Please will you expand it? Didactylos: Thanks for the heads up! We will contact the webmaster so that this question gets a proper answer in the FAQ's. |

OK, so this is just preliminary data about organic molecular dynamics?
Will the data found be freely available, or will it cost anyone who wishes to use it (commercially or non-profit purposes)? I don't really want my cpu time going to a commercial endeavour unless the data is free for all to use for any reasonable purpose. |

It's WCG policy. No project runs on this grid unless the final data product is made public and WCG is making sure it will go public. See About page and posts by bbover3 discussing this in recent days.

Hello ajpr,
You can download the Request for Proposal document from http://www.worldcommunitygrid.org/projects_showcase/viewSubmitAProposal.do This includes a sample contract. In return for running on our computers (for free) the research institute agrees to release the results to the public domain. So anybody can use them. Lawrence |

yes it would be nice to see organic solar cells... one of the bigest downfalls of solar (besided night)
---------------------------------------- is the fact that alot of the production of the inorganic cells have lots of waste products and there is disposal issues too...and yes there are cells out there that top the 30+% range but have ya looked at the price of them personaly i would prefer to get 20 or so of the 5-10% range instead of trying to pay for a 25%+ range and the price keeps going up dependin on the extra little bit of a % yes inexpensive and more eco friendly is definatly the way to go for solar reserch...  |

Those are all great answers. Thank you!
I was just wondering though about the graphics and if we (the layperson) can gain any insight? For example, Seti@home lets you see the energy of each block of radio spectrum your work unit is looking at. Any signal appears as a spike usually (and they are always from satellites and such). So the average person can see what is happening. Maybe I need a "WCG for dummies"  |
