Single junction silicon PV technology has reached the extremely impressive feat of 26.7% power conversion efficiency but is forever shackled by the thermodynamic limits of Schockley and Queisser to efficiencies below 30%. Multijunction technology is the roadmap for mass deployment of photovoltaic technology beyond 30% - raising the fundamental limit to 45% for silicon tandem and 49% for triple junction. In a few short years the perovskite technology has reached 23.3% in single junction and in tandem with silicon achieved 27.3% - exceeding for the first time the very best silicon single junction. Theoretical combination of existing best-in-class single junctions predict obtainable tandem and triple junction efficiencies of 34% and 39% respectively. So what is between us and the 34% efficient perovskite-silicon tandem? We discuss the specific challenges to overcome and our progress on the tandem roadmap beyond 30%, addressing fundamental loss mechanisms in the perovskite absorber and its contact heterojunctions as well as aspects of optical design and deployment in mono or bifacial format. We will address how these solutions can be delivered at the full wafer-scale in a production environment at rates of tens of thousands of wafers/hr.
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.
