Dye solar cell and organic solar cell scientists

13 05 2009

The HOPV09 (Hybrid and Organic Photovoltaics) Conference, chaired by Juan Bisquert, was celebrated in Benidorm, Spain, 10-13 may 2009. Contributions of outstanding quality were presented that provide an excellent outline of the up-to-date themes in dye-sensitized and organic solar cells. The Book of Abstracts gives a good overview of the topics that DSC and OPV scientists are pushing right now.

Many people considered that the HOPV09 Conference was very successful in providing a relaxed atmosphere that united a focussed community. So we talked of continuing the series with a HOPV10 in may 2010 in some nice italian location, under the supervision of Filippo de Angelis.


Energy and Environmental Science

I am grateful to the Editor-in-Chief, Professor Nathan Lewis (Caltech), to the Editor Philip Earis, and the rest of the Editorial Board of the journal Energy & Environmental Science (EES), for inviting me to join the Advisory Board of the journal.

EES is a new journal linking all aspects of the chemical sciences relating to energy conversion and storage, alternative fuel technologies and environmental science. EES is a very high profile and high impact international journal that has already produced very high quality papers on dye-sensitized and organic solar cells. Here I highlight just two of them.

The first paper by Joe Hupp and his colleagues, outlines the main strategies to improve the DSC on several fronts (dyes, redox shuttles, photoanodes, etc.). They also analyse the improvement that is realistically feasible with each strategy. It is an important paper to measure future developments of DSCs.

Advancing beyond current generation dye-sensitized solar cells ” Thomas W. Hamann, Rebecca A. Jensen, Alex B. F. Martinson, Hal Van Ryswyk, Joseph T. Hupp, Energy Environ. Sci., 2008, 1, 66-78.

In another paper, C. Brabec from Konarka and his colleagues review polymer tandem solar cells. This configurations consists on a monolythic integration of two solar cells in series that allow an optimized absorption of the solar photon spectrum, and has raised a lot of interested in the OPV community.

Professor Nathan Lewis, Editor-in-Chief of EES, has been recently  recognised as number 17 on a list of the 100 people who are changing America – one above Al Gore. Link

Organic solar cells over 6% efficient

1 05 2009

This week, researchers reported on polymer solar cells that convert about 6.1 percent of the energy in sunlight into electricity–inching a bit closer to the 10 percent that they say will be needed to gain a significant foothold in the market. Polymer solar cells have been increasing at a rate of about 1 percent a year.
