Inkjet printing is expected to fast track the commercialization of organic solar cells. Researchers from the KAUST Solar Center have exploited this technique to generate high-efficiency solar cells at large scales.

Organic photovoltaic materials could soon replace inorganic semiconductors in solar-powered devices because of their lightness, flexibility and low cost. These materials are easy to modify and process in solution, which makes them highly attractive for customization and large-scale production. In particular, customized solar cell designs can be used in conjunction with other printed electronics to power a plethora of applications, such as disposable electronics, intelligent packaging, interactive printed media and lab-on-a-chip devices.

Nonfullerene acceptors are emerging materials that have helped boost the efficiency of organic solar cells close to commercialization. These components are typically blended with electron donors in a light-responsive electrochemical layer. They have proven effective for drawing the light-generated pairs of electrons and negatively charged holes apart and maintaining electric current when exposed to sunlight. However, scale-up and manufacturing challenges have hindered efforts to transfer these materials from the laboratory to industrial and consumer-ready scales.

Concentrated Solar Power and the better-known photovoltaic panels — what’s the difference, and is one better than the other?

By converting heat to focused beams of light, a new solar device could create cheap and continuous power.

Tiny light-emitting microalgae, found in the ocean, could hold the secret to the next generation of organic solar cells, according to new research carried out at the Universities of Birmingham and Utrecht.

Microalgae are probably the oldest surviving living organisms on the planet. They have evolved over billions of years to possess light harvesting systems that are up to 95 per cent efficient. This enables them to survive in the most extreme environments, and adapt to changes our world has seen over this time-span.

Unravelling how this system works could yield important clues about how it could be used or recreated for use in new, super-efficient organic solar panels. Because of the complexity of the organisms and the huge variety of different species, however, progress in this area has been limited.

Thankfully, it’s unlikely the solar array could be weaponized into an orbiting “death ray”.

Forget solar power, forget wind, forget any expensive and polluting way of generating energy! Cold fusion is here, people, and it has been scientifically proven to exist at room temperatures, in a simple experimental lab jar.

As NASA seeks cost-effective access to destinations across the inner solar system, including cislunar space and Mars, it also seeks to shorten the cycle of time to develop and infuse transformative technologies that increase the nation’s capabilities in space, enable NASA’s future missions and support a variety of commercial spaceflight activities.

NASA’s Solar Electric Propulsion (SEP) project is developing critical technologies to extend the length and capabilities of ambitious new science and exploration missions. Alternative propulsion technologies such as SEP may deliver the right mix of cost savings, safety and superior propulsive power to enrich a variety of next-generation journeys to worlds and destinations beyond Earth orbit.

Energized by the electric power from on-board solar arrays, the electrically propelled system will use 10 times less propellant than a comparable, conventional chemical propulsion system, such as those used to power the space shuttles to orbit. Yet that reduced fuel mass will deliver robust power capable of propelling robotic and crewed missions well beyond low-Earth orbit — sending exploration spacecraft to distant destinations or ferrying cargo to and from points of interest, laying the groundwork for new missions or resupplying those already underway. Mission needs for high-power SEP are driving the development of advanced technologies the project is developing and demonstrating including large, light-weight solar arrays, magnetically shielded ion propulsion thrusters, and high-voltage power processing units.

Just as the modern computer transformed our relationship with bits and information, AI will redefine and revolutionize our relationship with molecules and materials. AI is currently being used to discover new materials for clean-tech innovations, such as solar panels, batteries, and devices that can now conduct artificial photosynthesis.

Today, it takes about 15 to 20 years to create a single new material, according to industry experts. But as AI design systems skyrocket in capacity, these will vastly accelerate the materials discovery process, allowing us to address pressing issues like climate change at record rates. Companies like Kebotix are already on their way to streamlining the creation of chemistries and materials at the click of a button.

Atomically precise manufacturing will enable us to produce the previously unimaginable.

An international research team led by The Australian National University (ANU) has made a new type of silicon that better uses sunlight and promises to cut the cost of solar technology.

The researchers say their world-first invention could help reduce the costs of renewable electricity below that of existing coal power stations, as well as lead to more efficient solar cells.

Senior researcher ANU Professor Jodie Bradby said silicon was used as the raw material for solar cells because of its abundance, low-cost and non-toxicity.
