In the future, solar cells can become twice as efficient by employing a few smart little nano-tricks.

Researchers are currently developing the environment-friendly solar cells of the future, which will capture twice as much energy as the cells of today. The trick is to combine two different types of solar cells in order to utilize a much greater portion of the sunlight.

“These are going to be the world’s most efficient and environment-friendly solar cells. There are currently solar cells that are certainly just as efficient, but they are both expensive and toxic. Furthermore, the materials in our solar cells are readily available in large quantities on Earth. That is an important point,” says Professor Bengt Svensson of the Department of Physics at the University of Oslo (UiO) and Centre for Materials Science and Nanotechnology (SMN).

My take on why the Trump Administration should make space-based solar power a real priority.

Space-based solar power — technology that would harvest solar energy directly in space for use on Earth — is a concept whose time has come.

“Two Tesla Motors veterans want to build a European counterpart to Elon Musk’s “gigafactory”, in an effort to stake out a dominant position in the fast-evolving supply chain for makers of electric vehicles.”

Inspired by origami, North Carolina State University researchers have found a way to remotely control the order in which a two-dimensional (2-D) sheet folds itself into a three-dimensional (3D) structure.

“A longstanding challenge in the field has been finding a way to control the sequence in which a 2-D sheet will fold itself into a 3D object,” says Michael Dickey, a professor of chemical and biomolecular engineering at NC State and co-corresponding author of a paper describing the work. “And as anyone who has done origami — or folded their laundry—can tell you, the order in which you make the folds can be extremely important.”

Nice.

MIT researchers have done even better. MIT has spunout a company called Sistine Solar that has developed a technology to print any kind of image on a skin that can be applied on solar panels, which change the appearance of the photovoltaic cells from all angles, without compromising on their capacity to generate electricity. Founded by the Sloan School of Management at MIT, Sistine Solar hopes to increase the adoption of clean energy with solar panels that mimic the surroundings or environment.

Researchers at the University of Minnesota and University of Milano-Bicocca are bringing the dream of windows that can efficiently collect solar energy one step closer to reality thanks to high tech silicon nanoparticles.

The researchers developed technology to embed the silicon nanoparticles into what they call efficient luminescent solar concentrators (LSCs). These LSCs are the key element of windows that can efficiently collect solar energy. When light shines through the surface, the useful frequencies of light are trapped inside and concentrated to the edges where small solar cells can be put in place to capture the energy.

The research is published today in Nature Photonics.
