Photovoltaic devices, or solar cells, are a means of generating electricity from sunlight in an environmentally friendly manner without emissions. Among the various types of solar cells, organic photovoltaics (OPVs) are known as lightweight, transparent, thin and flexible solutions.

OPVs generally consist of a charge donor layer, a charge acceptor layer, and two electrodes for charge extraction....

Measuring distance is perhaps the most ancient of human scientific activities. As such, distance measurements pervade modern scientific and industrial space, including construction, engineering, and health. Now, graphene is playing a key role in improving precision of distance measurements, down to sub-nanometer level.

Single emitters of light, such as dye color molecules, semiconductor quantum...

Electrical properties of graphene, such as conductivity, can vary across a wafer, which can impede the industrial acceptance of the material. Spatial inhomogeneity of conductivity results in devices from the same batch having different performance, which is incompatible with large scale manufacturing. It is hence important to have tools to map electrical properties with sufficient resolution...

Geothermal is currently the most underutilized of renewable resources, even though it is in principle, via engineered geothermal systems (also called enhanced geothermal systems, EGS), possible to exploit anywhere. A key issue with deep geothermal exploitation is its high cost, with 53% of the price of exploitation expended on drilling. This is especially true for deep EGS in hard rock (HDR – Hot...

Researchers at the University of Exeter have used CMOS-compatible processes to create graphene-based humidity sensors with performance on par with commercial ones. The process was demonstrated on an array of sensors produced on a 4” silicon wafer as well as on transparent and flexible PET. The work paves the way to practical use of 2D materials in low-cost, low-power, wearable and flexible...
