The aim of the project is to produce energy for IoT devices from ambient artificial light using solar cells based on the CuGaSe2 semiconductor. The development of low-temperature syntheses of this semiconductor will be necessary in order to be able to manufacture the solar cells on a flexible polyamide substrate. The use of heavy alkali-based post-treatments should enable the quality of the absorber and junction to be improved, and hence photovoltaic conversion efficiencies. Finally, material consumption will be optimised by reducing the thickness of the layers making up the cell stack, and the toxic CdS-based buffer layer will be replaced by an alternative buffer layer based on non-toxic and abundant materials.
