A review on solution-processed perovskite/organic hybrid photodetectors

Both perovskites and organic semiconductors are promising candidates for next-generation portable and wearable photodetectors (PDs), owing to their facile solution processibility and remarkable optoelectronic features. In recent years, there has been growing interest in combining the two and constructing perovskite/organic hybrid PDs, which are demonstrated to present a broad photoresponse spectrum, high photoresponsivity and good environmental stability. Since great progress has already been made, a comprehensive summary would be very important for this field. However, this is still lacking. In this review, we provide a thorough progress report and in-depth discussion on the perovskite/organic hybrid PDs, from the very fundamental device operation principles to advanced design strategies. Firstly, the main parameters of the PD devices are introduced. Then, the developments of the perovskite/organic hybrid PDs, including photodiodes, photoconductors and phototransistors, are discussed in detail. Finally, current challenges are summarized and potential solutions are proposed.

Automated summary

Perovskite/organic hybrid photodetectors combine the advantages of perovskites and organic semiconductors, showing a broad photoresponse spectrum, high photoresponsivity, and good environmental stability. Despite significant progress in this field, challenges remain and ongoing research is needed to address them.
