| dc.description.abstract | Due to its ease of developed, low cost of manufacture, excellent solar cells properties, and comparatively high performance, organicinorganic Quantum dotes hybrid perovskite solar cells have grown a lot of attention in the photovoltaic research community in recent year. This makes it more superior to other current solar cell materials. Lead, Bromine, Tn -based perovskites (CH3NH3BX3, X= Cl, I, Br,B=Pb, and Tn) Solar cells recently achieved a high efficiency of 26%, more than the efficiency of most thin film and organic solar cells. The poisonous presence of lead (Pb) poses a challenge for the commercialization of MAPbX3. So, numerical analysis for both Quantum disk model and program will play a key role in dealing with these solar cell issues because numerical analysis allows for flexibility in the design of practical problems and easy modeling with various hypotheses. Sometimes, a complete collection of device characteristics can be quickly produced with little time and higher accurate. Solar cell numerical analysis is carried out using a variety of simulation applications. We used the Solar cell capacitance simulator (SCAPS), and Quantum disk model program in this study, A numerical guide was suggested to improve the Power conversion efficiency(PCE) of an experimentally developed solar cell in order to achieve successful design for powerful solar cells. According to the findings, the thickness of the absorber layer and interface defects have a significant impact on the PCE of a solar cell. The standard design of a planar heterojunction perovskite-based solar cell is as follows: Back electrode/ Hole Transport Material (HTM)/ Perovskite absorber / Electron Transport Material (ETM) / Transparent electrode. Recent research has revealed that increasing the effective density of states and maximizing charge collection by changing the absorber thickness will improve the performance of planar heterojunction-based solar cells. In perovskite-based solar cells, electron transporting materials are also important. Numerical simulations of the effect of various electron transporting materials on the final behavior of the Photovoltaic (PV) system are also possible. Several PV parameters, including absorber thicknesses, HTM, and ETM, can be developed using simulation methods and then applied. The effective density of states and acceptor concentration, as well as the work-function of the back contact metal, have all been seen to have a considerable impact on system performance. Even with these clear advantages, improvements in hole mobility and conductivity of HTM, perovskite stability, and toxic lead replacement remain critical. The device's reliability and efficiency can be improved by properly processing/synthesizing perovskite absorbers, best engineering the selective contact, and increasing the conductivity of HTM and ETM. The history of perovskite materials from their discovery to their current importance as the key constituent of a new class of photovoltaic devices is examined in this thesis. We also look at how numerical simulation methods can be used to figure out the best configuration for perovskitebased solar cells and analyze their optoelectronic activity. The results of a simulation analysis using the Solar Cell Capacitance Simulator as a simulation tool based on the position of the various components of the solar cell are discussed. An efficiency of photo conversion of 46.58%, Voc =9.81V, Jsc = 46.9 mA/cm² and FF = 10.11%, has been found after optimizing the different parameters involved. To further study in depth and nanoscale the behavior of quantum dot solar cells, we have studied the perovskites using quantum disk theory. Due to its superior properties, Quantum dot (QD) nanocrystals have been proposed for high-efficiency solar cells, and this work is devoted to studying the quantum efficiency of perovskites. / ZnO, Perovskits / TiO2, Perovskits / PCBM, Perovskits / Cu2O Perovskits / SnO2 QD solar cells. in the six chapter; Assuming the quantum disk shape of QDs. assuming the QD layers are n and p perovskits/ETL and perovskits/HTM while the QDs are perovskits. | |
