Organo-metal halide perovskite based solar cells (PSCs) have attracted great research attention as a low-cost photovoltaic technology. The state-of-art research has achieved very high power conversion efficiency (PCE) of 22%. However, most of the high PCEs were achieved on cells with tiny working area of ~0.1 cm2 and very short lifetime. As well known, the measurement errors will be enlarged when the active cell area gets smaller. Moreover, the poor stability and large hysteresis in current-voltage scanning may further open the debate on the reliable characterization of the device performance. Therefore, it is crucial to advance efficient and stable PSCs with larger working area, which will accelerate the research of perovskite solar cells for future application.
In this presentation, I will demonstrate our works to achieve high cost-performance PSCs with working area of over 1 cm2. [1-2] First, we developed a new method to enable a better charge separation in planar heterojunction PSCs. This work can enhance the long-term stability of the device which performed a good stability of 1,000 hours under simulated solar light (AM 1.5G). Second, we developed the soft-cover deposition method to enable high cost-performance perovskite solar cell. Third, an annealing-free deposition method will also so be introduced for large-area high quality perovskite films.

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.
