Bart, co-founder of Media52 and Professor of Journalism oversees IO+, events, and Laio. A journalist at heart, he keeps writing as many stories as possible.

Every Sunday we look back at the most important stories of the past week. This edition revolves around a technology that has been announced for years as “the next step,” but now truly seems to be breaking through: perovskite solar cells.

The promise of perovskite is great. This new generation of solar cells is not only cheaper to produce than traditional silicon variants, but also more flexible and potentially more efficient. As classical solar panels reach their physical limits, perovskite opens the door to lighter, bendable applications, from facades to vehicles. With that, solar energy shifts from a static solution to an integrated part of our built environment.

Yet the story is not a simple victory of new technology over old. The biggest challenge lies in the stability and lifespan of perovskite cells. It is precisely there that intense work is now being done worldwide, also in the Netherlands. Researchers and companies are working to reduce the material's vulnerability without compromising its advantages. That is increasingly succeeding, and that explains why investments and pilot projects are increasing at a rapid pace.

What makes this development extra interesting is the geopolitical dimension. Europe is seeking ways to reduce its dependence on Asian solar panel production. Perovskite could play a strategic role in this because the production chain has not yet been fully “claimed” by existing market leaders.

So the question is no longer whether perovskite will play a role, but how quickly and at what scale. If the current breakthroughs continue, this technology could fundamentally change the energy landscape and give Europe a new opportunity to take a leading position.

But there was much more of interest

The battle between media and Big Tech over AI reaches a new peak in Germany. Publishers are resisting the use of their content for AI training without compensation. The conflict touches the core of journalistic independence and the revenue model of news.

The share price of ASML is under pressure after the decision by TSMC to order new high-NA EUV machines later. The postponement shows the tension between technological ambition and economic reality.

Residents see opportunities in heat networks, but also significant barriers. Research by TNO shows that uncertainty about costs and impact weighs at least as heavily as sustainability. Acceptance remains crucial for the energy transition.
