Hybrid organic-inorganic perovskite (HOIP) memristors are being studied extensively in recent times as a potential alternative to conventional memory technologies as well as to mimic the function of biological synapse in neuromorphic circuits [1]. In this work, the conduction mechanism and performance of MAPbI3-based memristors have been studied. These devices exhibited an excellent ON/OFF ratio of greater than 103. However, it has been found that measurement procedure brings significant variations in their performance [2]. While the RESET voltage and current significantly increase with scan rate, the ON/OFF ratio increases significantly with compliance current. Also, the forming voltage and ON/OFF ratio decrease with device scaling. In the case of voltage pulse characterization, the ON/OFF ratio can be enhanced by increasing the pulse amplitude and width. Hence, the selection of proper pulse amplitude and width is of utmost importance in achieving high endurance with desired noise margin. Based on these results, a protocol has been identified for the characterization of HOIP memristors to achieve their best possible switching parameters. This protocol is quite general in nature and can be employed for any other memristor structure based on HOIPs as well as on other related materials. Furthermore, the experimental data fitting to a standard SPICE based analytical model indicates that the current conduction is dominated by a tunnelling mechanism in the OFF state and is ohmic in the ON state [3].

International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
