Organometallic halide based thin film PV has achieved research device efficiencies of 23.7 %, surpassing other thin film PV technologies in less than a decade of research. However, hysteretic behavior caused by ion movement in perovskite semiconductor affecting charge carrier extraction can inhibit a reliable performance measurement. This behavior, reflected in transient current variations following voltage alteration, can be dependent on preconditioning of the sample, scan rate, temperature and the composition of the perovskite solar cell stack itself.
Therefore, a reliable performance comparison of perovskite solar cells is non-trivial. We examine the robustness of maximum power point tracking (MPPT) using three measurement algorithms to compare the performance of three n-i-p planar perovskite stacks. Moreover, we extract the relevant measurement parameters for a reliable MPPT. Figure shows how the measurement delay affects the measured performance of a solar cell for each of the studied algorithms.
As the result of the study, we propose a measurement protocol to determine the device PCE applicable in everyday laboratory testing of perovskite solar cells. Finally, we draw attention to the importance of defining a robust and universal measurement procedure for comparison of various perovskite based thin film PV devices researched in the community.
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.
