Metal-halide perovskite (MHP) photovoltaic (PV) modules are progressing towards commercialization. One major hurdle that remains is establishing confidence in long-term field performance and durability of MHP modules. A lot of progress has been made in addressing many reliability issues in MHP cells and modules; however, there is still work to be done to understand degradation and demonstrate real world operation of this technology. In addition to establishing field performance and reliability, in the absence of established test protocols for MHPs, many reliability studies have been conducted using the International Electrotechnical Commissions 61215-series (IEC 61215) of standardized tests, which do not yet have specifications for MHP modules. While some of the existing IEC 61215 protocols may be partially relevant to degradation mechanisms incurred by MHPs, a set of testing protocols specifically relevant to this technology is likely needed to ensure that accelerated testing can accurately assess the reliability of MHPs. Here, I will present a brief overview of an initial field demonstration of MHP modules as part of the Perovskite PV Accelerator for Commercializing Technologies, PACT, program. In addition, I will discuss accelerated testing results in the development of a test procedure for the qualification of commercial MHP modules. Particular attention will be given to light and elevated temperature testing, which has shown a particularly large impact on MHP performance but is not thoroughly covered in IEC 61215.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
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.
