Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature’s method, using sunlight to drive chemical reactions that generate clean energy. However, creating synthetic systems that work as organically as natural photosynthesis has been a significant challenge until now.

“The first involved integrating the hole-selective materials and the perovskite layers, to simplify the manufacturing process. The second involved replacing traditional organic materials, such as fullerene and bathocuproine, with tin oxide, an inorganic electron transport layer, in a process known as the atomic layer deposition method,” per PV’s description.

Labspeak aside, the big takeaway is that the changes resulted in a 25% efficiency, meaning the cells can turn a quarter of the sunlight hitting them into energy. What’s more, they maintained 95% of their efficiency after 2,000 hours of operation, per the report.

“The device structure reported in this study represents the most simplified architecture in the current field of perovskite solar cells, offering significant advantages for industrialization,” study co-author Gao Danpeng said in the story.

An international research team has fabricated a 1 cm² perovskite-silicon tandem solar cell that utilizes a top cell based on a perovskite absorber integrating inorganic copper(I) thiocyanate (CuSCN).

A co-deposition strategy of CuSCN and perovskite is firstly developed to solve the key technical…

A Saudi-Chinese research team has fabricated a perovskite-silicon tandem solar cell without a hole transport layer (HTL) in the perovskite top cell. This innovative strategy, based on the co-deposition of copper(I) thiocyanate and perovskite in the top cell absorber, was intended at solving typical issues of HTLs in tandem devices.

British startup plans to supply solar power from space to Icelanders by 2030, in what could be the world’s first demonstration of this novel renewable energy source.

The space solar power project, announced on Monday (Oct. 21), is a partnership between U.K.-based Space Solar, Reykjavik Energy and Icelandic sustainability initiative Transition Labs.

Last month, Oxford PV’s breakthrough solar cell broke the efficiency world record and is the world’s first commercially available Perovskite solar panel.
How does it work? And what does this mean for the future of solar?

The efficiency and performance of photovoltaics (PVs) have improved significantly over the past decades, which has led to an increase in the adoption of solar technologies. To further enhance the performance of solar cells, energy researchers worldwide have been devising and testing alternative design strategies, leveraging different materials and cell structures.

What we can learn from the critically endangered species.

Solar cells could be printed out like newspapers after Australia’s leading science organisation opened a $6.8 million facility dedicated to flexible solar technology.

The CSIRO launched its state-of-the-art Printed Photovoltaic Facility in south-east Melbourne on Wednesday, following more than 15 years of research into the renewable energy technology.

Researchers said printed, flexible photovoltaic cells could not only lower the cost of solar energy but could be used to deliver power in challenging areas such as space exploration, defence and disaster recovery.

While wind and solar energy are the two most viable clean alternatives to the dirty energy sources that power most of our society, the energy that can be harvested from ocean waves also has a lot of potential as an infinitely renewable source.

However, the technology is still developing, and a new research tool may play a big part in helping it get there, Interesting Engineering reported.

The new device, the marine and hydrokinetic toolkit, was developed jointly by the National Renewable Energy Laboratory, Pacific Northwest National Laboratory, and Sandia National Laboratories. It offers validation and standardized analysis tools to help researchers figure out whether their wave energy-gathering technologies are going to be viable without forcing them to undergo expensive and difficult real-world testing.

The type of semiconductive nanocrystals known as quantum dots are both expanding the forefront of pure science and also hard at work in practical applications including lasers, quantum QLED televisions and displays, solar cells, medical devices, and other electronics.
