It is very exciting that we get to host the #perovskite evaporation community in Freiburg! The Vacuum Deposited Perovskite Conference is in full swing. We are loving the focused scientific discussion it has already sparked! vacuumdepositedperovskite.org

My account name and profile promise science, but these days I mostly post about gardening and train trips. On the other place, I used to have a separate account for my research group and I liked that separation. So I will try doing that again. Welcome to the Sky: @jborchertlab.bsky.social !

A very garden heavy dinner tonight. Courgette, beans, and purslane pesto all from my allotment. I am delighted that I have anything to harvest after a late start to the garden year and a record drought / heatwave.

A plate, on it: half a courgette, topped with melted cheese, a bunch of green beans, and a swirl of spaghetti

Spent a couple of hours in the garden today pottering around, weeding, and even harvesting a bit. One of my most prolific weeds is common purslane, which is edible. So weeding and harvest are the same thing. Cleared half a bed to sow kale, got 1.5kg of purslane.

Time to turn this batch of my grape harvest into something storable! I have weighed it now and apparently I currently have 6,25 kg of grapes in my kitchen. Let's go!

I took over an allotment in June. Turns out right before a historic drought and heatwaves, is a bad time to start a garden. The last 3 months have been absurd. Very grateful to the previous allotmenteers who planted grapes. Only plant that was remotely happy this summer! Picked 'a few' grapes today.

First day back, after teaching at a summer school, and I am delighted to find a copy of @spiegel.de on my desk. It includes the article 'Victory of the Sun' which highlights the many successes of solar cells of recent years, including my research into #perovskite silicon tandem solar cells.

Delighted to see our latest research out in the world. We continue to optimise methods to make perovskite-silicon tandem solar cells. With our collaborators we were able to gain deep insights into the processes that happen during film formation. This knowledge is important to scale this technology.

I take trains pretty frequently so I've had quite a lot of odd train experiences in several countries. But today was a first. The train I was on, accidentally abandoned one of its conductors at a tiny train station we were not even meant to stop at. I am puzzled!

Sind diese "guten Hitzeschutzpläne" hier mit uns im Raum? Quelle Berlin Table, @mkreutzfeldt.bsky.social u.a.

Ein stärkeres Engagement des Kanzlers ist nicht geplant. Das Thema zur „Chefsache“ zu machen, werde „das Wetter nicht ändern“, sagte Regierungssprecher Stefan Kornelius am Montag. Grundsätzlich sieht er auch keinen großen Handlungsbedarf. „Es gibt gute Hitzeschutzpläne“, sagt Kornelius. Und: „Die Klimastrategie der Bundesregierung wirkt.“ Der Deutsche Städtetag und die Opposition im Bundestag kritisieren die Regierung dagegen scharf. Die Kommunen bräuchten dringend mehr Geld, sagte der Hauptgeschäftsführer des Deutschen Städtetags, Christian Schuchardt, Table.Briefings.

This is the main meadow in my local park. Normally on a rain free weekend like today, it is full of students picnicking, playing spikeball, and chatting. Today it is totally deserted. Glad to see people are smart enough not to be in the sun in 37°C temperatures. Sad to see the grass so dead.

Maximum temperature in Freiburg (Breisgau) was 39°C today. At 8pm it is still 37°C outside. In my flat it is 30°C. So about 1°C increase since yesterday. So the insulation is actually not bad, but we are on day 9 of temps over 35°C and warm nights, so no way to cool the flat down naturally anymore.

It is 8am the next morning and I have managed to 'cool down' my flat to 28.6°C. The local forecast for today is 38°C. #heatwave #climatecrisis

Here in Freiburg we are on day 10 of temperatures over 30°C. Day 8 of over 35°C. Even nighttime temperatures are in the mid 20s (higher between buildings), making it hard to cool down flats even with open windows overnight. It is 8pm. My flat is at 29°C, the outside temperature is still 37°C.

I keep rechecking the weather forecast cause I cannot fully believe that the whole next week will have 35°C+ temperatures. I have resources and will somehow cope (not yet sure how). Am worried for many others who will not be able to cope with these scorching temperatures. #heat #climatechange

This might be one of the funniest chart about energy scenarios I’ve seen. You can hardly see “actual” for gas

Winners and Losers
The IEA overestimated gas growth in Asia and underestimated solar

Gas
• Forecast 547 TWh
• Actual 17 TWh

Solar
• Forecast 465 TWh
• Actual 1,333 TWh

Note: Shows expected growth in Asian power generation between 2018 and 2025, based on actual 2018 generation, actual 2025 generation, and the 2018 World Energy Outlook's Current Policies Scenario estimates for 2025. Actual 2025 generation figures are from Ember.
