For solar energy to provide a significant fraction of the world’s electricity mix the balance of systems (BOS) cost has to be further reduced. Modules can reduce the BOS cost with improvements in performance. Hybrid tandem photovoltaics, two different semiconductor technologies used in a single tandem device, are a promising solution to improve the efficiency of the module without greatly increasing the module cost. Recent advancements in perovskite solar cells have vaulted their power conversion efficiency to over 15%. High efficiencies, low energetic losses between absorber bandgap and device voltage, low-temperature processability, cheap precursor materials, and the possibility to tune the absorber materials bandgap by simple chemical substitution, make these materials ideal candidates for use as the top cell in a double-junction tandem. We replace the opaque metal back electrode of perovskite solar cells with a solution processed silver nanowire transparent top electrode. We mechanically stack the 'semi-transparent' device in a 4-terminal tandem configuration onto CIGS cells and demonstrate the first net efficiency improvement of a commercial grade solar cell using the hybrid tandem concept. This work paves the way for integrating perovskites into a low cost and high efficiency (25-30%+) multijunction cell and highlights the potential for the mass adoption of the hybrid tandem format by the photovoltaic industry.
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.
