Utilizing Perovskite based CuFeS nanoparticles as bio sensors


Project Description

Perovskite based nanocrystals have gained high interest over recent years as a revolutionary material system for low cost and highly efficient photovoltaic devices. A recent addition to this class of materials if Copper Iron Sulphate nanocrystals (CuFeS), due to their relatively long wavelength response they have not been considered for photovoltaic applications. However they hold great promise in terms of developing low cost infrared image sensors and for in vivo bio sensors. An industrial partner, have developed a new and patented synthesis technique for these nanocrystals allowing quick, easy and repeatable production of the nanoparticles in large quantities. However to further progress this material and its potential applications it is now essential to investigate fabricating and characterizing opto electrical devices from these materials. This project will investigate alternative routes to form high quality, uniform thin layers of this material (i.e. spin coating, printing and evaporating). Metal contacts will subsequently be deposited before electrical and optoelectrical characterization of the resulting devices will be undertaken. This will be repeated in an iterative process to find optimum processing conditions, allowing high efficiency devices to be realized.

The quantum dots and resultant devices will be characterized using a wide range of techniques including; electron microscopy, Photoluminescence, Atomic Force Miscopy, electrical characterization (e.g. IV and CVs) and spectral response measurements.
This project will involve working as part of a multidisciplinary team incorporating, Physicists, Chemists, Electrical Engineers and Material Scientists. It will also involve close working with an industrial partner based at Daresbury including potential periods of secondment with them.
