Perovskite materials have been an opportunity in the Li–ion battery technology. The Li–ion battery operates based on the reversible exchange of lithium ions between the positive and negative electrodes, throughout the cycles of charge (positive delithiation) and discharge (positive lithiation).
The properties of perovskite-type oxides that are relevant to batteries include energy storage. This book chapter describes the usage of perovskite-type oxides in batteries, starting from a brief description of the perovskite structure and production methods. Other properties of technological interest of perovskites are photocatalytic activity, magnetism, or pyro–ferro and piezoelectricity, catalysis.
Tandem solar cells with a perovskite top cell and crystalline silicon (c-Si) bottom cell have reached certified efficiencies of 28% (on 1 cm2 by Oxford PV) in just about 4 years. This success is mainly attributed to the optimized design in the perovskite top cell and the crystalline silicon bottom cell.
Precisely, we focus on Li-ion batteries (LIBs), and their mechanism is explained in detail. Subsequently, we explore the integration of perovskites into LIBs. To date, among all types of rechargeable batteries, LIBs have emerged as the most efficient energy storage solution .
Perovskite solar cells are the main option competing to replace c-Si solar cells as the most efficient and cheap material for solar panels in the future. Perovskites have the potential of producing thinner and lighter solar panels, operating at room temperature.
The perovskite solar cell applications are quite diverse, thanks to this technology featuring unique characteristics like a high-adsorption coefficient, long carrier separation transport, a larger distance between electrons and holes, and the capacity to be tuned to absorb different light colors (wavelengths) from the solar spectrum.
Perovskite/silicon tandem solar cells have reached certified efficiencies of 28% (on 1 cm 2 by Oxford PV) in just about 4 years, mostly driven by the optimized design in the perovskite top cell and crystalline silicon (c-Si) bottom cell. In this review, we focus on the structural adjustment of the bottom cell based on the structural evolution ...

Crystalline silicon is limited to absorbing wavelengths equal to or superior to 1,100 nm, while perovskites can be tuned to respond to a wider variety of colors in the solar spectrum. This feature can be exploited in the future, creating solar panels that convert most wavelengths in the solar spectrum. Perovskite solar cells also have the ...
Perovskite materials have been associated with different applications in batteries, especially, as catalysis materials and electrode materials in rechargeable Ni–oxide, Li–ion, and metal–air batteries. Numerous perovskite compositions have been studied so far on the technologies previously mentioned; this is mainly because perovskite ...
Perovskite is much better at absorbing light than crystalline silicon and can even be ''tuned'' to use regions of the solar spectrum largely inaccessible to silicon photovoltaics. Perovskite holds a much better tolerance for defects and can function well with impurities and imperfections.
