A group of international researchers has devised an innovative and ground-breaking technique which allows integration of single-crystal hybrid perovskites into electronics. The synthesis of perovskite requires low temperatures which, in turn, has opened up a new avenue for further enhancing and producing flexible electronics on a large scale. Further, the technique has the potential required to substantially cut down on the manufacturing costs that go into the production of electronic devices. Hybrid perovskite exhibits the properties of both organic and inorganic substances and can be manufactured from inks. The ink used to synthesize perovskites make them amenable and a perfect material to be utilized in the roll-to-roll fabrication of electronic components. Currently, perovskites are being studied extensively to gauge their potential of use in an array of devices such as light emitting diodes, photodetectors, and solar cells. However, the daunting challenge in the use of perovskites is its integration with classical electronic devices such as transistors.
The research found out that single-crystal perovskite differs from their polycrystalline counterparts on the basis of defects found in each of the substances. The presence of more defects in polycrystalline perovskites was found out to adversely affect a material’s electronic properties and thus made the perovskites unsuitable for use in the manufacturing of electronic devices.
While trying to integrate the single-crystal perovskite with transistor researchers discovered that the main hindrance in the process was the rough and uneven edges of the macroscopic crystals. Researchers divulged that they overcame the problem by manufacturing the perovskites crystals using two laminated surfaces. According to the researchers, the technique helped them develop a single-crystal perovskite with sharp edges which was ready to be integrated with a transistor without any modifications. It was further reported that the electrical properties of the crystal being developed can be modified by choosing different halides while synthesizing the product.
The researchers claimed that they had managed to create a transistor integrated with the single-crystal perovskites integrated into it. Notably, the resources required in the production of these crystals help in reducing the overall cost of manufacturing electronic devices. Further, the properties exhibited by the single-crystal perovskites make them compatible with flexible substrates making them suitable for use in wearable electronics and Internet of Things (IoT) applications. The versatile nature of the perovskites crystals and the low cost of production makes it a lucrative opportunity for electronic manufacturing to cash on.
