The Future of Hybrid and Inorganic Perovskite Materials: Technology Forecasting

Perovskite (PSK) materials have received extensive attention because of their potential use as the active layer of different applications, including capacitors, sensors and detectors, memories, catalysts, fuel cells, and optoelectronic devices (solar cell and light‐emitting diode). Herein, the past, current, and future status of these applications are focused on. The state of each application is investigated using diverse technology indicators. It reveals that among all the applications, the optoelectronic application is the youngest one and has not yet reached the technology growth stage though it possesses most of the recently published patents. Using a technology investment potential evaluation method, the most potent area for investment is explored, indicating that detectors and sensors are the ones with the biggest investment potentials. Remarkably, PSK solar cell dedicates more than 70% of the patents to itself with the highest predicted efficiency of 30% that will be achieved in 2023 according to the curve fitting method and in 2030 according to the S‐curve method. As a perspective, currently, the highest efficiency and stability are achieved for small‐sized PSK solar cells, it is expected that they would be commercialized in electronic equipment applications first, and after overcoming the challenges, large‐scale modules would enter the markets.
