The Rise of Perovskite Solar Cells: Technology, Markets and Players

The Rise of Perovskite Solar Cells: Technology, Markets and Players

Jul 7, 2015 Worldwide
Pervoskite photovoltaics are a breath of fresh air in the photovoltaic market. They demonstrated a remarkable learning curve, going from 2.2% efficiency in 2006 to the latest record of 20.1% in 2014. They have already supressed OPVs and DSSCs and are now, at least in terms of efficiency, in the same range as leading thin film PVs like CdTe and CIGS. Perovskite solar cells are now an active area of research across many organisations. In this…

IDTechEx Research addresses global megatrends

Jul 7, 2015 Worldwide
We are sometimes asked how we choose the topics in which we specialise. There are several answers but certainly we choose topics that overlap and address the major technological and societal megatrends of this century. Four particularly come to mind.
New lithium ion battery is safer, tougher, and more powerful

New lithium ion battery is safer, tougher, and more powerful

Jul 6, 2015 Korea
Researchers have created a new lithium ion battery made from a porous solid which greatly improves its performance as well as reducing the risks due to overheating.
New nanogenerator harvests power from rolling tires

New nanogenerator harvests power from rolling tires

Jul 3, 2015 United States

Micro-supercapacitor structure inspired by intricate design of leaves

Micro-supercapacitor structure inspired by intricate design of leaves

Jul 2, 2015 Korea
Chemical batteries store a lot of energy but require a long period of time for that energy to charge and discharge plus have a limited lifespan. Capacitors charge quickly but cannot store enough charge to work for long enough to be practical.
