Bourns has introduced a series of miniature resettable thermal cut-off (TCO) devices for dense, high capacity lithium-ion battery packs. The Model AC series offers five trip temperatures: 72, 77, 82, 85 or 90°C (all +/-5°C) – the latter of which “is capable of carrying up to 20A at 60°C, making it the highest current-carrying TCO ...

Researchers at the University of Michigan have found a way to stack solution-processed organic solar cells on top of vacuum-processed cells, creating an tandem solar cell with 15% efficiency. “For the last couple of years, efficiency for organic photo-voltaics was stuck around 11 to 12%,” said Michigan physicist Xiaozhou Che. The top solution-processed non-fullerene-acceptor cell ...

The university of Manchester has made a 1GHz thin-film transistor from amorphous IGZO – indium gallium zinc oxide. The devices, created with Shandong University in China, are made on a high-resistance silicon substrate using Ta2O5 gate dielectric. The material is 80% transparent, opening the door to display applications. “Making a high performance device, like our GHz ...

Pyroelectricity could extract energy from heat sources below100°C, offering an alternative to thermo-electric generators (TEGs). TEGs make electricity through the Seebeck effect, where different conductive materials in contact develop a potential difference across the contact point. Pyroelectric materials, in contrast, develop a potential across a crystal of one material due to electrons shifting as a ...
