Summary from Kohesio (English machine translation by the source): The result of the project will be a new type of silicon-based PV cell, made using low-dimensional structures. Classic cells operate within a limited range of light wavelengths. They have high conversion efficiency in the visible and low light range, outside this range. Manipulation of absorption outside the visible spectrum will increase energy yields. An innovative feature of the project is the use of low-dimensional structures functionalised in such a way as to allow for direct passivation of the silicon surface, which allows the manufacturing process to be simplified. Simplification will consist of eliminating two high-temperature technological steps, which will reduce energy consumption and cell production costs. Physically, cells will be based on a phenomenon called conversion of infrared energy upwards and down conversion of UV radiation. Conversion of infrared radiation will reduce the nominal operating temperature of the cell. This will reduce the efficiency losses of silicon cells by up to a dozen percent. The use of nanomaterials will allow effective use of UV radiation. Thanks to the down conversion process, it will be possible to convert UV radiation, which is not optimal for silicon cells to the range of VIS – the range of optimal operation of the silicon cell. Down conversion using quantum dots can take place in the process of multiphotonic generation. This will translate into improving the efficiency of the cell. Additional advantages of using low-dimensional structures are: personalisation of the color of a link by controlling the size of the coating of a quantum dot and the use of low-dimensional structures as glowing layers. Finally, we'll get a silicon-based photovoltaic cell but refined with nanomaterial layers. Translating
