“Most materials have a fixed ability to conduct heat, but applying voltage to this thin film changes its thermal properties drastically. Materials whose electronic and magnetic properties can be significantly changed by applying electrical inputs form the backbone of all …
“Physicists from Switzerland and Germany have unveiled fingerprints of the long-sought particle known as Mahan exciton in the room temperature optical response of the popular methylammonium lead halide perovskites. The optical properties of semiconductors are governed by the so-called “excitons …
“University of California, Berkeley, scientists have created a blue light-emitting diode (LED) from a trendy new semiconductor material, halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices. In the process, however, the researchers discovered …
“New material should be relatively easy to produce at an industrial scale, researchers say. MIT researchers have improved on a transparent, conductive coating material, producing a tenfold gain in its electrical conductivity. When incorporated into a type of high-efficiency solar …
“Harnessing the sun’s rays to produce solar power is an expanding industry with positive environmental impacts. As sunlight reaches semiconducting materials, it is converted into electricity through a photovoltaic system of solar cells, generating renewable, clean energy that can …
News NTU Singapore and Dutch scientists show how perovskite solar cells can capture more electricity
“Scientists from Nanyang Technological University, Singapore (NTU Singapore) in a collaboration with the University of Groningen (UG) in the Netherlands, have developed a method to analyse which pairs of materials in next-generation perovskite solar cells will harvest the most energy …
“Invisible infrared light accounts for half of all solar radiation on the Earth’s surface, yet ordinary solar energy systems have limited ability in converting it to power. A breakthrough in research at KTH could change that. A research team …
“Solar perovskite materials could be spiked with organic cation dopants to suppress decomposition and degradation. Expanding the list of organic ingredients that comprise perovskite solar materials could boost their long-term stability and performance, KAUST researchers have predicted. Perovskites have recently …
“Scientific instrument made at McGill reveals liquid-like properties of a solid substance McGill University researchers have gained tantalizing new insights into the properties of perovskites, one of the world’s most promising materials in the quest to produce a more …
“RFID-based devices work in indoor and outdoor lighting conditions, and communicate at greater distances. By 2025, experts estimate the number of “internet of things” devices — including sensors that gather real-time data about infrastructure and the environment — could rise to …
