The technological demands for high-efficiency solar cells have stimulated research on transparent conductive oxide (TCO) films. High electron mobility is needed to achieve high conductivity with improved visible and near-infrared transparency. In addition, low temperature growth with low plasma damage is also required for deposition when the TCO films are deposited on absorbing layers of solar cells and/or substrates sensitive to heat and ion bombardment. Historically, polycrystalline (poly-) Sn-doped In2O3 (typical Sn/In ratios are 3–10 at.%) or amorphous (a-) In-Zn-O by magnetron sputtering have been used for solar cells as standard TCOs to achieve moderate mobility (~ 50 cm2V-1s-1) using low growth temperatures. Recently, solid-phase crystallized (spc-) H-doped In2O3 (In2O3:H) and transition metal (Me) and H co-doped films (In2O3:Zr,H, In2O3:W,H, In2O3:Ce,H) with low Me contents (typical Me/In ratios are ~1 at.% or less) with significantly higher mobility (80–160 cm2V-1s-1) have been developed. These films can be fabricated by magnetron sputtering, reactive plasma deposition with lower energy ion bombardment, and atomic layer deposition without ion bombardment at process temperatures of 150–180°C. The advantage of the TCO materials and film growth have been demonstrated in Si heterojunction solar cells (> 23%), Si thin-film triple junction solar cells (14.0%), and CIGS mini-modules (20.93%) with high conversion efficiency. Here, we introduce our recent works on the TCO layers for the solar cells.
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.
