Solar modules to contribute for aesthetically pleasing energy-plus buildings

Photovoltaic and solar thermal systems are not always considered aesthetically enhancing to a building. The coloured modules, however, being developed at the Fraunhofer Institute for Solar Energy Systems ISE are refreshingly challenging this perspective. Inspired by the phenomen that causes the shimmerings shades of blue or green of the wings of the morpho butterfly, the Read more about Solar modules to contribute for aesthetically pleasing energy-plus buildings[…]

Photovoltatronics viewed as smart solar revolution

Imagine you’re walking through the city on a sunny summer day. You look at the skyscrapers, the shop buildings, lampposts and electric taxis driving tirelessly to and fro. What you can’t see is that every single piece of their surface is generating and storing its own electricity. The solar cells on these surfaces are interconnected Read more about Photovoltatronics viewed as smart solar revolution[…]

A new electromagnetic radiation shield

A printable ink with an unsurpassed conductivity and transparency tradeoff has been developed by a KAUST team for use in solar panels, and for the novel blocking of electromagnetic waves. Metals, such as copper and gold, generate little heat when a current flows through them. For this reason, these high-conductivity materials are used extensively in Read more about A new electromagnetic radiation shield[…]

Biosolar cells to produce more energy

By combining light-collecting and photosynthesis proteins of different types, more energy can be produced. Potential sources of renewable energy include protein complexes that are responsible for photosynthesis. However, their efficiency in technical applications still leaves much to be desired. For example, they cannot convert green light into energy. A research team from Ruhr-Universität Bochum (RUB) Read more about Biosolar cells to produce more energy[…]

New technique way that could advance the solar industry

The researchers showed they could rapidly grow a large amount of high-purity CdTe material,a more than Read more about New technique way that could advance the solar industry[…]

A new energy map for energetic losses

A new spectroscopic method now makes it possible to measure and visualise the energetic landscape inside solar cells based on organic materials. It was developed by a research team led by Prof. Dr Yana Vaynzof, a physicist at Heidelberg University. This novel visualisation technique enables scientists to study the physical principles of organic photovoltaics with Read more about A new energy map for energetic losses[…]

Imagine a truck tarp that can harvest the energy of sunlight!

With the help of new textile-based solar cells developed by Fraunhofer researchers, semitrailers could soon be producing the electricity needed to power cooling systems or other onboard equipment. In short, textile-based solar cells could soon be adding a whole new dimension to photovoltaics, complementing the use of conventional silicon-based solar cells. Solar panels on building Read more about Imagine a truck tarp that can harvest the energy of sunlight![…]

A new nanomaterial increase extra efficiency of solar cells

A new nanomaterial made from phosphorus, known as phosphorene, is shaping up as a key ingredient for more sustainable and efficient next-generation perovskite solar cells (PSCs). PSCs which are one of the fastest developing new solar technologies and can achieve efficiencies comparable to more commonly used commercially available silicon solar cells. For the first time, Read more about A new nanomaterial increase extra efficiency of solar cells[…]

Perovskite solar cells: perfection not required!

Experiments at BESSY II reveal why even inhomogeneous perovskite films are highly functional Metal-organic perovskite layers for solar cells are frequently fabricated using the spin coating technique. If you follow the simplest synthesis pathway and use industry-relevant compact substrates, the perovskite layers laid down by spin coating generally exhibit numerous holes, yet attain astonishingly high Read more about Perovskite solar cells: perfection not required![…]

Engineered quantum dots could bring down the cost of solar electricity

Using two types of “designer” quantum dots, researchers are creating double-pane solar windows that generate electricity with greater efficiency and create shading and insulation for good measure. It’s all made possible by a new window architecture which utilizes two different layers of low-cost quantum dots tuned to absorb different parts of the solar spectrum. “Because Read more about Engineered quantum dots could bring down the cost of solar electricity[…]
