Highly efficient and low-cost perovskite solar cells (PSCs), one of the most promising next-generation photovoltaic technology, triggered intensive research around the world. Up till now, PSCs have achieved the record power conversion efficiency of 25.7% and the device stability has been improved substantially. To push forward the development of PSCs, researchers from home and abroad have been overcoming the obstacles of commercialization. According to our estimation of the levelized cost of electricity, the key to future applications is to reduce the cost of PSCs which strongly depend on high efficiency and long stability. In this presentation, I will introduce our recent works on promoting the efficiency and stability of PSCs from aspects of crystallization, passivation, and ion-migration blocking.
We introduced a perovskite crystal array (PCA) with regular distribution to assist the growth of the perovskite absorption layer. The PCA provided nuclei where the crystallization can commence without overcoming the critical Gibbs free energy for nucleation and induces a controllable bottom-up crystallization process under solvent annealing. As a result, the device achieved power conversion efficiency of over 25.1%. Furthermore, we constructed a composite electrode of copper-nickel (Cu-Ni) alloy stabilized by in situ grown bifacial graphene. The device with the copper-nickel electrode showed an efficiency of 24.34% (1cm2) and stability: 95% of their initial efficiency is retained after 5,000 hours at maximum power point tracking under continuous 1 sun illumination.
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.
