AI Customer ServiceElectro-optics is the technology that uses electrical signals to control optical properties. It is one of the most useful areas of photonics. In this article, you will learn about why electro-optics is important as well as how it is used in various photonic applications. Why are electro-optic effects so important?
The properties that we report were determined for materials totally representative of those used in high-efficiency devices. Our findings establish electro-optic design rules that we believe are generic for perovskite solar cells and provide further insight into how these systems work as photovoltaic materials.
Accurate knowledge of the cell's optical constants allowed improved modelling and design, and using this information we fabricated an optimized device with an efficiency of 16.5%. The optimized devices have ∼ 100% spectrally flat internal quantum efficiencies and minimal bimolecular recombination.
Because of the nature of these devices, the electronic and optical properties of the materials are key to device performance. The relationship among materials growth and processing, the resulting electro-optical properties, and device performance can be extremely complex and difficult to determine without direct measurement of these properties.
As a matter of fact, electro-optics is the “bridging technology” between electronics and photonics. It is a hybrid technology which combines the best aspects of electricity and light. In a previous blog post, the special relationship between electronics and photonics is discussed in depth.
Organohalide-perovskite solar cells have emerged as a leading next-generation photovoltaic technology. However, despite surging efficiencies, many questions remain unanswered regarding the mechanisms of operation. Here we report a detailed study of the electro-optics of efficient CH 3 NH 3 PbI 3 -perovskite-only planar devices.
