☀️ Researchers from our university, together with colleagues from CSEM, have achieved a record 30% efficiency for triple-junction solar cells, which combine two thin-film perovskite cells and one silicon cell on a single device. The milestone could advance affordable next-generation solar technologies for space and terrestrial applications.

A published study explains how Resonant Soft X-ray Scattering (#RSoXS) measurements were carried out at the SST-1 beamline (NSLS-II) to investigate #nanostructural features in organic #SolarCell materials. Researchers used the soft X-ray-sensitive CCD detector to capture high-resolution 2D scattering patterns at a photon energy of 285.4 eV and a sample-to-detector distance of 35 mm.

@researchbuzz "This innovative approach presents a new way to produce lightweight, flexible solar films that can be used on surfaces such as rooftops and other unconventional surfaces that could not normally stand the weight of solar panels. Together with their anticipated low cost, this could significantly enhance the roll out of solar, particularly in developing countries, and make a real difference in the drive to replace fossil fuels with sustainable solar energy."

Waste-based perovskite solar cell achieves 21.39% energy efficiency

A team of materials scientists and solar engineers at Nanyang Technological University in Singapore, working with a colleague from Polytechnique Hauts-de-France, has developed a perovskite solar cell using a biomass-based polymer. In their paper published in the journal Advanced Functional Materials, the group describes how they used agricultural waste to make the photoactive layer of the cell, and in so doing, found that it was still energy efficient.

The next-generation #SolarCell is fully #recyclable

12 February 2025
Anders Törneholm

"In a study published in Nature, researchers at Linköping University have developed a method to recycle all parts of a solar cell repeatedly without environmentally hazardous #solvents. The recycled solar cell has the same efficiency as the original one. The solar cell is made of #perovskite and the main solvent is water."

my first #offgrid #meahtastic node is online... it doesn't feel quite right yet and mistakes have definitely been made, but that's what you learn from? what you can see here: a #nibble from wonderful @skickar paired with a 5W #solarcell and a small buffer battery with charging electronics. The battery will be replaced by a 10Ah #LiPo and the solar cell will also grow. next version will be built with a #rp2040 or with a #nrf52840 or maybe ... many thanks to your inspiring talk at #38C3 Kody!
