Renewable energy in Japan will receive a seismic shift via perovskite solar cells, the latest development that would change the way solar energy is viewed. Lightweight, flexible, and adaptable, these solar cells will provide a more viable means to producing energy within a city, responding to shortages of land and sustainable issues. Let’s see how Japan is benefiting from the PSC technology to bring about a green future.
Japan is currently utilizing its competitive advantages to lead the rest of the world into the new renewable energy age. Under its revised energy plan, the Ministry of Industry now prioritizes PSCs on Section 0 of its plan wherein Japan aims to develop PSC sections generating 20 gigawatts of electricity equivalent to 20 nuclear reactors by fiscal 2040.
The strategy was designed to be closely aligned with the country’s commitment to net-zero emissions by 2050. At the center of this strategy is Japan’s position as the second-largest iodine producer in the world, a necessary ingredient in the manufacturing of perovskite solar cells.

In a bold move towards a sustainable future, Helsinki, Finland’s capital, has installed the world’s largest heat pump, a groundbreaking piece of technology that has the capacity to power 30,000 homes. This ambitious project is a significant step in the fight against climate change, utilizing renewable energy sources to provide a reliable and efficient heating system even in the coldest of winters. In this article, we’ll explore how this technological marvel works, its environmental impact, and the potential it has to change energy production on a global scale.
Helsinki’s heat pump represents a major breakthrough in energy technology. The system works by transferring heat from a colder environment to a warmer one, ensuring maximum energy efficiency. One of the most impressive features of this heat pump is its use of carbon dioxide as a refrigerant, which allows the pump to generate heat at temperatures of up to 90°C.
A standout innovation is the oil-free compressor, a key component that ensures the system operates efficiently while minimizing its environmental footprint. This marks the first time such a system has been implemented on this scale, reinforcing Finland’s commitment to adopting sustainable solutions for energy production. By using renewable energy sources like wind and solar power, this heat pump reduces the need for fossil fuels and helps Finland move towards a more sustainable energy future.
Researchers have developed a battery capable of converting nuclear energy into electricity through light emission, according to a new study.
Nuclear power plants generate about 20% of the electricity in the United States and produce minimal greenhouse gas emissions. However, they also generate radioactive waste, which poses risks to human health and the environment, making safe disposal a significant challenge.
To address this, a team led by researchers from The Ohio State University designed a system that harnesses ambient gamma radiation to generate electricity. By combining scintillator crystals—high-density materials that emit light when exposed to radiation—with solar cells, they successfully converted nuclear energy into an electric output powerful enough to run microelectronics, such as microchips.
Nano-enhanced perovskite solar cells last 10x longer by trapping iodine, paving the way for durable, affordable solar technology.
Dr. Benjamin Cardenas: “We tend to think about Mars as just a static snapshot of a planet, but it was evolving. Rivers were flowing, sediment was moving, and land was being built and eroded.”
Did an ocean exist on ancient Mars that might have been suitable for life as we know it? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as an international team of researchers led by Guangzhou University and the Chinese Academy of Sciences investigated the possibility of an ancient shoreline in the northern hemisphere of Mars that could have been home to an ancient ocean. This study has the potential to help researchers better understand the environmental conditions on ancient Mars and whether they were suitable for life as we know it.
For the study, the researchers analyzed radar data obtained from China’s Zhurong rover, which landed in a northern region on Mars called Utopia Planitia in May 2021. However, Zhurong stopped functioning after researchers put it in hibernation mode in May 2022 and the rover never woke up, likely due to dust covering its solar panels. Despite this, the researchers of this study presented evidence of an ancient shoreline in Utopia Planitia that mirrors coastal sediments observed on the Earth called “foreshore deposits”
“We’re seeing that the shoreline of this body of water evolved over time,” said Dr. Benjamin Cardenas, who is an assistant professor of geology at Penn State and a co-author on the study. “We tend to think about Mars as just a static snapshot of a planet, but it was evolving. Rivers were flowing, sediment was moving, and land was being built and eroded. This type of sedimentary geology can tell us what the landscape looked like, how they evolved, and, importantly, help us identify where we would want to look for past life.”
Researchers have developed a battery that can convert nuclear energy into electricity via light emission, a new study suggests.
Nuclear power plants, which generate about 20% of all electricity produced in the United States, produce almost no greenhouse gas emissions. However, these systems do create radioactive waste, which can be dangerous to human health and the environment. Safely disposing of this waste can be challenging.
Using a combination of scintillator crystals, high-density materials that emit light when they absorb radiation, and solar cells, the team, led by researchers from The Ohio State University, demonstrated that ambient gamma radiation could be harvested to produce a strong enough electric output to power microelectronics, like microchips.
Quantum light sources are fickle. They can flicker like stars in the night sky and can fade out like a dying flashlight. However, newly published research from the University of Oklahoma proves that adding a covering to one of these light sources, called a colloidal quantum dot, can cause them to shine without faltering, opening the door to new, affordable quantum possibilities. The findings are available in Nature Communications.
Quantum dots, or QDs, are so small that if you scaled up a single quantum dot to the size of a baseball, a baseball would be the size of the moon. QDs are used in a variety of products, from computer monitors and LEDs to solar cells and biomedical engineering devices. They are also used in quantum computing and communication.
A research study led by OU Assistant Professor Yitong Dong demonstrates that adding a crystalized molecular layer to QDs made of perovskite neutralizes surface defects and stabilizes the surface lattices. Doing so prevents them from darkening or blinking.
Researchers at North Carolina State University have demonstrated a new technique that uses light to tune the optical properties of quantum dots—making the process faster, more energy-efficient and environmentally sustainable—without compromising material quality.
The findings are published in the journal Advanced Materials.
“The discovery of quantum dots earned the Nobel Prize in chemistry in 2023 because they are used in so many applications,” says Milad Abolhasani, corresponding author of a paper on the work and ALCOA Professor of Chemical and Biomolecular Engineering at NC State. “We use them in LEDs, solar cells, displays, quantum technologies and so on. To tune their optical properties, you need to tune the bandgap of quantum dots—the minimum energy required to excite an electron from a bound state to a free-moving state—since this directly determines the color of light they emit.
This process, which cannot be understood satisfactorily by classical physics alone, occurs constantly in green plants and other photosynthetic organisms, such as photosynthetic bacteria. However, the exact mechanisms have still not been fully elucidated. Hauer and first author Erika Keil see their study as an important new basis in the effort to clarify how chlorophyll, the pigment in leaf green, works.
Applying these findings in the design of artificial photosynthesis units could help to utilize solar energy with unprecedented efficiency for electricity generation or photochemistry.
