Advanced Perovskite Solar Cells

The energy crisisEnergy crisis is a huge challenge facing the world today. Natural resourcesNatural resources such as coalCoal and oilOil are consumed in large quantities and their reserves are gradually decreasing. It is imperative to advocateEnergy conservation energy conservation. Meantime, it is very important to develop greenGreen and clean energyClean energy. Solar energySolar energy has become one of the most promising green energyGreen energy sources in recent years because of its sustainableSustainable and safe advantages. Solar energy can be converted into effective energy such as heatHeat energyEnergy throughPhotoelectric conversion photoelectric conversion because it doesn’t produce harmful gasesGas, solid wasteSolid waste, and other pollutantsPollutant in the conversionConversion process. In addition, the new solar cellsSolar cell have the advantages of low costCost, cleanliness, and they are efficient. Since 2009, a new type of perovskite solar cellPerovskite solar cell has developed rapidly. In orderOrder to further improve the photoelectric conversion efficiencyConversion efficiency of batteriesBattery, more researchers in recent years have tried to apply new ceramicCeramic materials (perovskite materialsPerovskite materials) to batteriesBattery, and have achieved remarkable results. Relevant research reports show exponential growthGrowth. Perovskite solar cells use crystalsCrystal with perovskite structurePerovskite structure as electron transferElectron transfer materials to improve the light absorptionAbsorption efficiencyEfficiency of the solar cellsSolar cell. Studies show that the structureStructure and performancePerformance of the electron transferElectron transfer layer directly affect the stabilityStability and life of the batteryBattery, which proves that the appropriate electron transferElectron transfer layer is very important. New perovskite ceramic materials have been widely used in solar cell devicesDevice. This chapter mainly introduces the most common perovskite thin filmsThin film and their preparation methods, organic–inorganicInorganic perovskite solar cellsPerovskite solar cell, etc., focusing on their development status, and the main factors affecting their stabilityStability. Finally, the currentCurrent problems and development prospects in the research and applicationApplication of perovskite solar cellsSolar cell are introduced, which will lay a solid foundation for the deeper understanding of perovskite solar cellsPerovskite solar cell and the preparation of new and efficient ones.
