Perovskite solar cells (PSCs) have made substantial progress in power conversion efficiency; however, their commercialization requires high operational stability. While environmental stressors such as moisture and oxygen can be mitigated through encapsulation, other factors including light exposure, electrical bias, and thermal fluctuations present persistent challenges.
A reliable approach for assessing the stability of PSCs is to evaluate their performance under Maximum Power Point Tracking (MPPT) conditions, as photovoltaic operation occurs at this point. We have developed a modular-scalable MPPT system capable of simultaneously measuring the aging of up to 240 solar cells under class A, AM1.5G illumination in an inert nitrogen (N₂) atmosphere, allowing for a realistic evaluation of the stability and long-term performance of solar cells, without the need of prior encapsulation. Additionally, we employ accelerated aging, a method that exposes solar cells to intensified stress conditions, such as elevated temperatures and illumination intensities above one sun. This method aims to simulate long-term degradation in a shorter time-period, facilitating the identification of potential failure mechanisms and stability limitations more efficiently than conventional aging tests.
Currently, the system is used for a range of long-term aging tests on Perovskite solar cells. In the poster, I will showcase the functional capabilities of our aging system, present the aging measurement data carried out on perovskite solar cells and conduct a comparative assessment of the long-term performance and degradation mechanisms.
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.
