To study the efficiency and the performances of thos solar cells, SCAPS-1D software is used in the simulation. The efficiency of MASnI3 and MAPbI3 based solar cell with various hole transport material (HTM) layers including Spiro-OMeTAD, PEDOT:Pss, and Cu2O is studied. Zinc oxide (ZnO) layer and TiO2 are proposed as electron Abstract ------------------------------------------------------------------------------------------------------------- transport layers the influence of defect density, absorber layer thickness, and working temperature on the performance of the device is presented. A simple process to put voices and texts on a laser beam and transmit it remotely via a perovskite solar cell (local wireless network based on perovskite solar cell programmed with the Arduino). This process is considered a fascinating example of amplitude modulation of light using sound vibrations. Therefore, the design and simulation of the perovskite solar cell will be described in detail in this work. A study and realization of a sustainable disinfection tunnel (SDT) to reduce viruses less harmful than the corona virus that are transmitted by touch, with the use of solar energy. A study and realization of a wifi station and solar-powered smart-phone chargers with a silver multi-coin selector, which highlights the green economy, as well as the opening of workstationsenPerovskite, CH3NH3SnI3, PEDOT:Pss, Copper oxide, Spiro-OMeTAD, ZnO, HTM, efficiency, SCAPS-1DThesis
