investigation of spin coating technique on efficiency of zn(ii) doped- lacro3 perovskite solar cells

High-efficiency solar cells are rarely used in normal applications today due to their very complex structure and very expensive raw materials. the use of perovskite solar technology is very cheap and it has a simple process for processing into photovoltaic cells. in this project, lacro3/zn(ii) doped perovskite structure was by co-precipitation method in the perovskite structure. we used spin coating technique for producing photo anode. the structure, shape and morphology of all compounds were identified. using uv-vis spectroscopy, the energy gap was calculated. at the end, estimated performances from two techniques, doctor blade and spin coating, were compared.
