Tech Record-breaking transparent solar panels pave way for electricity-generating windows Groundbreaking solar cells could be used in windows, greenhouses and glass facades, as well as in the screens of portable electronic devices
Gaza’s solar revolution: Renewable energy provides solution to blackouts Your support helps us to tell the story From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference. Read more Scientists have achieved a new efficiency record for dye-sensitized solar cells (DSCs), opening up new commercial possibilities for transparent solar panels .
A team from École Polytechnique Fédérale de Lausanne in Switzerland made the breakthrough using specially designed photosensitizer dye molecules that when combined are capable of harvesting light from across the entire visible light spectrum.
The transparent properties of DSCs make them suitable for use in windows , greenhouses and glass facades, the researchers said, as well as in the screens of portable electronic devices.
They are also flexible, relatively low-cost and can be made using conventional roll-printing techniques. Theoretically, the price/performance ratio is also good enough to allow them to compete with fossil fuel electrical generation.
The first commercial applications are already being realised, with dye-sensitized solar windows installed in the SwissTech Convention Center, however their capacity for generating electricity has so far been restricted by their lack of efficiency compared to traditional solar cells.
The latest development pushes the power conversion efficiency to between 28.4-30.2 per cent, while still maintaining long-term operational stability over 500 hours of testing.
“Our findings pave the way for facile access to high performance DSCs and offer promising prospects for applications as power supply and battery replacement for low-power electronic devices that use ambient light as their energy source,” wrote the authors of a study detailing the technology.
The study, titled ‘Hydroxamic acid preadsorption raises efficiency of cosensitized solar cells’, was published in the scientific journal Nature on Wednesday.
