Perovskite based photodetectors and hybrid devices possess distinctive properties which have enabled considerable practical applications since perovskite is an ideal candidate for higher sensitivity and response speed. In this work, an elegant approach of fabricating hybrid photodetectors based on perovskite-metallic nanostructures is shown. By combining gold triangle nanoantennae with a CH3NH2PbI3 film, a simple yet effective fabrication method of hybrid organic-inorganic perovskite photodetectors with improved performanceis experimentally demonstrated. Finite difference time domain calculations agree well with experimental results. Perovskite-assisted devices are highly attractive due to their unique properties and the results shown in this work may find extensive potential applications for novel flexible photodetectors and other related optical devices.
