What are Perovskites?
Perovskites have great potential in industries such as solar energy and may stand to replace Silicon one day in converting light to energy.
Perovskites offer high power conversion efficiencies and low production costs. It is also used in LED technology as efficient and tunable light-emitting materials, and in fields like catalysis, sensors, and optoelectronics.
At HORIBA, we recognize the importance of perovskites in scientific and industrial advancements. Our standard microscope spectroscopy solutions support researchers and industries in analyzing perovskite materials for their specific needs and characteristics. The SMS system is multimodal – enabling several spectroscopies such as Raman, PL and TRPL, etc. on one platform. With the added benefit of sample co-location across different techniques, enabling micron-scale correlative spectroscopy.
Perovskites, named after the mineral calcium titanate, were discovered in Russia's Ural Mountains. These minerals have a distinctive crystal structure. This structure, characterized by a three-dimensional arrangement of atoms, includes a large central cation surrounded by an octahedral array of smaller anions, endowing perovskites with remarkable light-absorbing properties and versatility.
These materials boast excellent optical and electronic properties, such as high-light absorption and efficient charge transport. Its tunable bandgaps allow for the modification of optical and electrical properties by altering their chemical composition. Perovskites’ impressive efficiency makes it a promising alternative to traditional silicon-based solar cells.
Perovskites have generated strong interest in the research and industrial communities for Photovoltaic {PV) applications. This is primarily due to their excellent solar conversion efficiency, low cost of fabrication, and ease of deposition on different substrates. However, the many advantages of perovskites for PV applications are countered by their equally strong vulnerabilities to degradation from prolonged exposure to light, high temperatures, moisture, and air pollution. This is in addition to other challenges inherent in fabricating uniform and high-quality perovskite films for commercial applications.
The challenges of developing stable perovskites and fabrication processes for commercial use require the use of several spectroscopic techniques such as Raman, Photoluminescence (PL), and Time-resolved photoluminescence (TRPL), and others. to characterize and optimize the material design and fabrication processes.
As research into perovskites advances, the energy-converting efficiency percentage continues to increase, approaching silicon.
