A research team led by Assistant Professor Shogo Mori and Professor Susumu Saito at Nagoya University has developed a method of artificial photosynthesis that uses sunlight and water to produce energy and valuable organic compounds, including pharmaceutical materials, from waste organic compounds. This achievement represents a significant step toward sustainable energy and chemical production.

The findings were published in Nature Communications.

“Artificial photosynthesis involves that mimic the way plants convert sunlight, water, and carbon dioxide into energy-rich glucose,” Saito explained. “Waste products, which are often produced by other processes, were not formed; instead, only energy and useful chemicals were created.”

Humans can do plenty, but plants have an ability we don’t: they make energy straight from sunlight, a superpower called photosynthesis. Yet new research shows that scientists are closing that gap.

Osaka Metropolitan University researchers have revealed the 3D structure of an artificial photosynthetic antenna protein complex, known as light-harvesting complex II (LHCII), and demonstrated that the artificial LHCII closely mirrors its natural counterpart. This discovery marks a significant step forward in understanding how plants harvest and manage , paving the way for future innovations in artificial .

The researchers, led by Associate Professor Ritsuko Fujii and then graduate student Soichiro Seki of the Graduate School of Science and Research Center for Artificial Photosynthesis, had their study published in PNAS Nexus.

A team of researchers has made an advancement in the field of multifunctional energy harvesting. Their latest study advances in understanding the photovoltaic effect in ferroelectric crystals.

The article, “Study on Influence of AC Poling on Bulk Photovoltaic Effect in Pb(Mg1/3 Nb2/3)O3-PbTiO3 Single Crystals,” published in Advanced Electronic Materials, reports the team’s recent research results regarding improving the electric output of the bulk photovoltaic effect (BPVE) via manipulation of ferroelectric domains in oxide perovskite crystals.

In ordinary , the mechanism of harvesting the solar energy and then converting them into green electricity is based on the formation of p-n junctions of semiconductors. While the p-n junction has been invented for more than a century, widely used in the silicon industry nowadays, the BPVE is a more recently discovered physical phenomenon from the 1960s–1970s.

An international team of researchers affiliated with UNIST has unveiled a novel cross-linker additive that significantly addresses the longstanding stability issues associated with organic solar cells, also known as organic photovoltaics (OPVs).

With the incorporation of just 0.05% of this cross-linking agent, the lifespan of OPVs can be improved by over 59%. Industry analysts suggest this breakthrough brings the commercialization of OPVs—regarded as next-generation solar cells—closer to reality.

Led by Professor BongSoo Kim in the Department of Chemistry at UNIST, the research team, in collaboration with researchers from the University of California, Santa Barbara (UCSB), the University of Lille in France, and the French National Center for Scientific Research (CNRS), identified the operational principles of this innovative cross-linker using a variety of advanced analytical techniques.

In an amazing achievement akin to adding solar panels to your body, a northeast sea slug sucks raw materials from algae to provide its lifetime supply of solar-powered energy, according to a study by Rutgers University–New Brunswick and other scientists.

“It’s a remarkable feat because it’s highly unusual for an animal to behave like a plant and survive solely on photosynthesis,” said Debashish Bhattacharya, senior author of the study and distinguished professor in the Department of Biochemistry and Microbiology at Rutgers–New Brunswick. “The broader implication is in the field of artificial photosynthesis. That is, if we can figure out how the slug maintains stolen, isolated plastids to fix carbon without the plant nucleus, then maybe we can also harness isolated plastids for eternity as green machines to create bioproducts or energy. The existing paradigm is that to make green energy, we need the plant or alga to run the photosynthetic organelle, but the slug shows us that this does not have to be the case.”

The sea slug Elysia chlorotica, a mollusk that can grow to more than two inches long, has been found in the intertidal zone between Nova Scotia, Canada, and Martha’s Vineyard, Massachusetts, as well as in Florida. Juvenile sea slugs eat the nontoxic brown alga Vaucheria litorea and become photosynthetic – or solar-powered – after stealing millions of algal plastids, which are like tiny solar panels, and storing them in their gut lining, according to the study published online in the journal Molecular Biology and Evolution.

The ultrafast dynamics and interactions of electrons in molecules and solids have long remained hidden from direct observation. For some time now, it has been possible to study these quantum-physical processes—for example, during chemical reactions, the conversion of sunlight into electricity in solar cells and elementary processes in quantum computers—in real time with a temporal resolution of a few femtoseconds (quadrillionths of a second) using two-dimensional electronic spectroscopy (2DES).

However, this technique is highly complex. Consequently, it has only been employed by a handful of research groups worldwide to date. Now a German-Italian team led by Prof. Dr. Christoph Lienau from the University of Oldenburg has discovered a way to significantly simplify the experimental implementation of this procedure. “We hope that 2DES will go from being a methodology for experts to a tool that can be widely used,” explains Lienau.

Two doctoral students from Lienau’s Ultrafast Nano-Optics research group, Daniel Timmer and Daniel Lünemann, played a key role in the discovery of the new method. The team has now published a paper in Optica describing the procedure.

TAMPA, Fla. — Star Catcher Industries, a startup designing spacecraft to beam solar energy to other satellites in low Earth orbit, has secured funding from Florida’s economic development agency to demonstrate the technology at a former Space Shuttle landing site.

Space Florida is providing a $2 million financial package for the one-year-old venture, Star Catcher CEO Andrew Rush told SpaceNews March 7, with most of the funds supporting tests this summer from Space Florida’s Launch and Landing Facility at the Cape — one of the longest runways in the world.

Rush said Star Catcher plans to use the facility to demonstrate its ability to beam hundreds of watts of energy to multiple simulated satellites simultaneously from more than a kilometer away, marking a critical proof point for the Jacksonville, Florida-based startup’s technology.

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.
