(DOE/Sandia National Laboratories) The Department of Energy recently awarded $14 million to form a Sandia National Laboratories-led center to improve the understanding of perovskite-based photovoltaic technologies and determine the best tests to evaluate the new solar panels’ lifetimes.
(DGIST (Daegu Gyeongbuk Institute of Science and Technology)) Perovskite colloidal quantum dots (Pe-CQDs) are highly promising nanocrystals for optoelectronic applications. However, the size of the crystals should ideally be equal to ensure a consistent energy landscape. In a recent study, scientists clarified the relationship between differences in particle size — polydispersity — and the optoelectronic characteristics of Pe-CQDs. They showed that using equally sized, or ‘monodisperse,’ quantum dots results in markedly better performance in Pe-CQD solar cells, paving the way for future optoelectronic devices.
(NYU Tandon School of Engineering) A team at the NYU Tandon School of Engineering has advanced a critical step in fabrication of Perovskite solar cells: p-type doping of organic hole-transporting materials within the cells. The research, “CO2 doping of organic interlayers for perovskite solar cells,” appears in Nature.
(ARC Centre of Excellence in Exciton Science) Research has revealed the structure of 2D perovskite thin films resembles a sandwich containing layers beneficial for generating electricity more efficiently in photovoltaics.
(Imperial College London) Scientists have uncovered the exact mechanism that causes new solar cells to break down, and suggest a potential solution.
(National Centre of Competence in Research (NCCR) MARVEL) Perovskite solar cells are among the most promising and cheapest photovoltaic technologies, but widespread application has been hampered by issues linked to long-term stability and processability. In a new paper, researchers including Prof. Michele Parrinello of Università della Svizzera italiana and ETHZ, and Paramvir Ahlawat, a PhD student of EPFL’s Ursula Reothlisberger, address this problem with a combined experimental and simulation study that could improve the design of industrial-scale processing techniques for two leading perovskites.
Researchers have used carbon dots, created from human hair waste sourced from a barbershop, to create a kind of ‘armor’ to improve the performance of cutting-edge solar technology. In a study,Â the researchers led by Professor Hongxia Wang in collaboration with Associate Professor Prashant Sonar of QUT’s Centre for Materials Science showed the carbon nanodots could […]

(Karlsruher Institut für Technologie (KIT) ) From cell to module without loss of efficiency: Researchers at Karlsruhe Institute of Technology (KIT) have managed to produce perovskite solar modules with minimum scaling loss. For this purpose, they combined laser-based series interconnections with vacuum processing of all layers of the solar cell. They achieved an 18 percent efficiency on an area of four square centimeters – a world record for vacuum-processed perovskite solar modules.
(NASA/Johnson Space Center) On March 14, the Paraguayan Space Agency (AEP) deployed a satellite from the space station to help track a tiny parasite that causes Chagas disease. The satellite, Guaranisat-1, is the first developed and put into orbit by Paraguay.
(DOE/Los Alamos National Laboratory) A new, simpler solution process for fabricating stable perovskite solar cells overcomes the key bottleneck to large-scale production and commercialization of this promising renewable-energy technology, which has remained tantalizingly out of reach for more than a decade.
