Dye-sensitized solar cell is a type of photoelectrochemical device proposed to replace conventional silicon-based photovoltaic devices. TiO₂ nanoporous layer, dye molecule and hole conductor are the key components for the design and fabrication of solid-state dye solar cell.¹ Dye-sensitized solar cells are produced at low cost from cheap starting materials, providing high solar to electric energy conversion efﬁciencies. Over the past decade, however, the efﬁciency improvements seen for DSSCs have been rather marginal, suggesting that more radical concepts might be required to achieve high conversion efﬁciencies. Concepts originally developed and successfully applied in the area of conventional photovoltaics, such as multi-junction or tandem solar cells for the development of high efﬁcient DSSCs. Among these p-type transporting materials, NiO is a wide band-gap (Eg = 3.55 eV) oxide semiconductor with superior thermal and chemical stability,² thus becomes a promising material in many applications such as transparent electrodes,³ electrochemical capacitors,⁴ electrochromic devices⁵ and photoelectrochemical devices.⁶ In this study, p-NiO is synthesized by hydrothermal technique using microwave oven. p-NiO is synthesized nickel acetate precursors. p-NiO material is characterized by Scanning Electron Microscopy and XRD analysis. NiO nanomaterial is important nanomaterial for p-type DSSC. Morphological and optical properties are discussed.

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.

MATSUS

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.

International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics
