Fullerene bisadducts are promising electron-accepting materials because of the increased open-circuit voltage of BHJSCs based on these compounds compared with those based on PCBM. That led researchers to synthetize C60 bisadducts connected with the strong absorber perylenediimide (PDI) in a cyclic fashion.
A novel battery electrode features silicon nanoparticles clustered like pomegranate seeds in a tough carbon rind. The Stanford/SLAC design could enable smaller, lighter rechargeable batteries for electric cars, cell phones and other devices.
A new breed of ultra thin super-material has the potential to cause a technological revolution. 'Artificial graphene' should lead to faster, smaller and lighter electronic and optical devices of all kinds, including higher performance photovoltaic cells, lasers or LED lighting.
The multifunctional 'smart' gold nanoshells could lead to more effective cancer treatments by overcoming a major limitation of modern chemotherapy techniques - the ability to target cancer cells specifically and leave healthy cells untouched.
The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: researchers have developed the first ever single-molecule LED. The device is formed from a single polythiophene wire placed between the tip of a scanning tunneling microscope and a gold surface. It emits light only when the current passes in a certain direction.
Researchers have taken a leap forward towards a deeper understanding of an undesired effect in thin film solar cells based on amorphous silicon - one that has puzzled the scientific community for the last 40 years. The researchers were able to demonstrate that tiny voids within the silicon network are partly responsible for reducing solar cell efficiency by some 10 to 15 percent as soon as you start using them.
McDermott Will and Emery offer their Special Report '2013 Nanotechnology Patent Literature Review: Graphitic Carbon-Based Nanotechnology and Energy Applications Are on the Rise' as a continuing study of trends observed in our 2013 and 2012 reports, and also present a renewed focus on trends in the energy sector.
