Streaming from the field of dye-sensitized solar cells, the first device architecture employing organic-inorganic lead halide material as a light harvesting material demonstrated power conversion efficiency (PCE) of 3.8% and no sooner the PCE upsurge to 22.1% certified efficiency in less than 10 years. This rapid rise in PCE is attributed to exceptional optoelectronic properties such as long carrier diffusion length, ambipolar charge mobility, band gap of 1.6 eV and above all to device engineering by simple solution process. However, perovskite solar cell suffers from long term stability as the material degrades into its non-photoactive byproducts, that is, MAI and PbI2. Efforts to improve the stability were performed by developing perovskite material based on compositional engineering, triple and multi-cation system. Also, interface engineering and recycling of degraded perovskite devices have been carried out at research laboratory level and long term stability up to several hours to weeks have been demonstrated however long term stability to several tens of years still remains a big challenge. On the other hand, the toxicity concern of lead (Pb) can become an obstacle for commercialization and has been reported to cause severe damage to nervous and reproductive system upon exposure. Tin (Sn), germanium (Ge) based perovskite were demonstrated to address the Pb toxicity issue but unfortunately they suffer from structural instabilities and recently toxicity concern of Sn perovskite has been reported as it releases large amount of hydroiodic (HI) acid into the environment.
Recently bismuth iodide in combination with silver iodide based cubic material was demonstrated as a promising material to replace lead halide perovskites. Herein we present our ongoing work on solvent engineering and the effect of various polymer hole transporting materials (HTM) to improve the morphology and stability of various silver-bismuth-halide (Ag-Bi-I) materials and also simultaneously improve the device performance.
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.
