Scientists in South Korea developed a foldable thin-film device with some promising characteristics. Integrating a perovskite cell material and a carbon nanotube electrode, the group fabricated a device that achieved 15.2% efficiency and could withstand being folded more than 10,000 times at a bending radius of 0.5mm.
A group of German scientists has analyzed the possible trajectory of carbon nanotubes (CNTs) in photovoltaic research and industry and has suggested a roadmap to bring this technology closer to mass production. Despite a large number of challenges, the academics predicted a brilliant future for CNTs in PV applications, explaining that the barriers to their adoption are constantly being reduced.
Scientists in South Korea have worked with graphene and carbon nanotubes to develop a working lithium-ion battery that can be stretched by up to 50% without damage to any of the components. According to the scientists, the battery represents a significant step in the development of wearable or body-implantable electronic devices.
Scientists in the United States have developed a carbon nanotube method of fabricating a lithium-ion battery with a silicon anode. The device reportedly demonstrated better than 87% capacity retention after 1,500 cycles. The developers say their discovery overcomes many of the obstacles to the use of silicon as an anode and could open up the use of other materials for electrodes in lithium-ion devices.
Scientists at the Tokyo Institute of Technology have developed a carbon nanotube which forms a strong junction with a lead-halide perovskite, improving performance and stability.
MIT scientists claim to have created a material 10 times more black than anything witnessed to date. It is said to be able to absorb more than 99.96% of incoming light and reflect 10 times less light than other superblack materials. The invention may be interesting for the development of black silicon PV technology and carbon nanotube-based solar cells.
Scientists at Rice University in Texas have developed a device which converts heat into light by squeezing it into a smaller bandgap. The ‘hyperbolic thermal emitter’ could be combined with a PV system to convert energy otherwise wasted as heat – a development the researchers say could drastically increase efficiency.
