Perovskite solar

Cross-post at CleanTechnica on perovskite solar cells.

Cross-post at CleanTechnica on recent progress in making cheap solar cells from synthetic perovskite crystals. If you are curious, it’s got enough links in it to stuff by people who actually know what they are talking about.

It was an interesting challenge for a dilettante, one I’m not in a hurry to repeat, to report on news at the research frontier to a general audience.

You shouldn’t take my piece as evidence that perovskites will win out over competing lines of development. My hunch in their favour is based on little more than an aesthetic pleasure in a project to use the very stuff of the earth’s rocks to save its biosphere, and a touch of alma mater sentimentality: one of the key labs is in Oxford. It is evidence that in the medium term pv solar is not limited to the current commercial menu, two sorts of silicon and one thin-film. The solar learning curve will continue. Just as well: it’s half of what stands between us and climate catastrophe.

CleanTechnica cut the photo of Michael Grätzel of Lausanne, the pioneer of the solar perovskite field. Doesn’t look like a superhero, but then real heroes don’t. The cell he’s holding is from a precursor project that did not pan out commercially, a useful reminder of the risks. I do hope he gets his Nobel.

James Wimberley (b. 1946, an Englishman raised in the Channel Islands. three adult children) is a former career international bureaucrat with the Council of Europe in Strasbourg. His main achievements there were the Lisbon Convention on recognition of qualifications and the Kosovo law on school education. He retired in 2006 to a little white house in Andalucia, His first wife Patricia Morris died in 2009 after a long illness. He remarried in 2011. to the former Brazilian TV actress Lu Mendonça. The cat overlords are now three. I suppose I've been invited to join real scholars on the list because my skills, acquired in a decade of technical assistance work in eastern Europe, include being able to ask faux-naïf questions like the exotic Persians and Chinese of eighteenth-century philosophical fiction. So I'm quite comfortable in the role of country-cousin blogger with a European perspective. The other specialised skill I learnt was making toasts with a moral in the course of drunken Caucasian banquets. I'm open to expenses-paid offers to retell Noah the great Armenian and Columbus, the orange, and university reform in Georgia. James Wimberley's occasional publications on the web

One thought on “Perovskite solar”

  1. Thanks for the research update for those of us who don't even rate as dilettantes. It will be interesting to see which technologies turn out to be successful.

    There's a (minor) typo in both posts: Grätzel's earlier cells are called dye-sensitized cells.
