The relaxing way to chat about science in Oxford

The Cafe Scientifique is a successful UK community the idea for which was originally imported from France. The Oxford Cafe was the fourth to be started and there are now dozens of Cafes Scientifiques across the British Isles, while the concept is also now spreading widely overseas. The point of the Cafe is to provide a public forum in which scientific ideas can be discussed informally involving scientists and non-scientists alike, aiming to inform, to entertain, and to provoke debate.

The Oxford Cafe Sci meets on the second Tuesday of each month except August, all are welcome and no scientific background is required. Visit the FAQ page for more information if you have never been to a Cafe event before.

The links on the left of this page give more details.


See the Cafe audio page for streaming audio files of many of the recent Cafe talks. These are usually the introductory talks, although several recent discussions have been recorded too. Some talks have associated image or presentation files linked. As a matter of policy audio files are not published straight away, but a minimum of a month and often several months later.

Tuesday 2nd February 2021 - Dr Sean Elias

Taming Sunlight: The Perovskite Photovoltaics Revolution

How do we decarbonise our energy sources? How mature is solar technology really? What is the future of photovoltaics? This talk will answer these questions with a focus on hybrid perovskites, a revolutionary new material that is unlocking next-generation solar technology.

Dr Suhas Mahesh is a postdoctoral scientist in the Department of Physics at the University of Oxford.

    During the CoVid-19 crisis our venue is closed and all in-person Oxford Cafes Scientifiques have been suspended. We are holding them online: please see below left for full details.

    Events will still open the online doors at 7pm, with half an hour for people to get themselves connected, chat online by message or voice if they want to, and settle down with drinks and nibbles as usual. We regret that the Cafe is unable to provide refreshments directly to the audience..... The talk will start at 7:30pm, with our customary short break after it finishes before starting the discussion via the chat. We will aim to finish the discussion at approx 9pm as normal.

    We take a break in August each year and will be back in September.

    During the epidemic we are holding the Cafe online.
    We will where possible hold Cafe evenings using Zoom, which needs only a browser and no registration (though many people may choose to download the app instead). For details of how to use this software if you have never done so, please see this document which explains how to, and also gives some details of how to find the various settings while you are in a meeting.

    The Zoom Meeting ID will be sent out only via the mailing list (see below) and there will be a limit of 100 people total.

    On the day of the meeting a private password for it will be circulated at about 2pm, again via the mailing list. Those on the mailing list are asked not to give the meeting details to others without the Cafe host's express permission - please instead ask them to sign up via the mailing list (they can remove themselves straight afterwards).


    We are very grateful for the help given by the Oxford University Museum of Natural History and its staff, for allowing us to use the visitor centre for our events, and giving us excellent practical support on Cafe nights. The help of Chris Jarvis, education coordinator, and the occasional lending of exhibits and items from the collection, is particularly appreciated.

    Online donations
    While we are unable to collect donations in the notorious Oxford Cafe Sci black hat, those who wish to support the enterprise are welcome to do so online by donating via https://paypal.me/CafeSci on Paypal. Please note that since we will not be incurring our usual speaker and meeting expenses, donations raised this way will go towards paying for the Zoom Pro subscription, and building a fighting fund to be able to invite speakers from more distant locations once we are all able to travel and meet again. There is absolutely no obligation whatsoever to donate as we are not currently losing money, but all gifts are greatly appreciated.
