Enhancement of GaAs solar cell efficiency by type-II GaSb quantum dots located outside of the depletion region
Experiments have shown that extrinsic intermediate band (IB) states, for instance, formed by artificial quantum dots (QDs), located in the depletion region participate in electron-hole recombination. This facilitates dramatically the dark current and reduces the [...]
A Focused Super-Continuum Solar Simulator for Illuminated Solar Cell Microscopy
The design and application of a novel, focused solar simulator based on a high-power, super-continuum laser is described. We used the simulator to create micrometer-scale spatial maps of full-spectrum optical beam induced current (FS-OBIC) in [...]
Water Splitting for H2 Production using Visible-light-responsive Photocatalysts
Huang J., Zhang G., Zhang W., Zhang G., Zhang W., Wang P., Minakata D., Chen Y., Crittenden J., New Jersey Institute of Technology, US
Hydrogen (H2) production using visible-light photocatalysis for water splitting has attracted considerable attention owing to the growing demand for environmentally friendly and sustainable energy sources. This presentation will demonstrate our previous study on H2 production [...]
Efficient broadband conversion via quantum dots with built-in charge
Recently proposed by ARL – University at Buffalo team, the Q-BIC technology is a promising basis for developing high-efficiency, broadband (all-weather), rugged, light-weight, scalable, and relatively inexpensive single-junction solar cells capable of converting of 35 [...]
Silver Nanowires for Plasmon Induced Enhancement of Optical Absorption in Thin-Film Silicon Solar Cells
Plasmonic effects for photovoltaics are investigated through this communication. We present here an innovative design with integrated silver nanocylinders located at the rear side of a thin crystalline silicon cell. Numerical simulations (FDTD) show that [...]
High open-circuit voltage bulk-heterojunction solar cells by using new dendritic acceptor material
Light harvesting solar cells and energy transfer are currently of great challenges for the 21st century in the field of solar cells energy. Academic and industrial scientists are searching for a detailed understanding of light [...]
Au nanoparticles decorated hydrothermally processed rutile TiO2 nanorods for photoelectrochemical water splitting
In this work, we investigate the synthesis of single crystalline rutile TiO2 nanorods for photoelectrochemical water splitting. A facile and convenient hydrothermal method was used to fabricate it. We realize the control of the length, [...]
Y2O3:Eu3+, Tb3+ sphere particles doped anti-reflection and wavelength conversion bifunctional films: Synthesis and application to solar cells
Ji R., Hu X., Tian M., Han L., Jun F., Wang L., Wang Y., Zhan S., Zhang Q., Zhang Q., Wang L., Wang Y., Northwest University, CN
Solar energy, as a clean and sustainable resource, has great potential to take place of the traditional energy source. While the low photoelectric conversion efficiency limits the application of solar cells to a great extent. [...]
Deposition of TiO2/Ni/CuO/ITO multi-layered cell for solar-driven water splitting
In this study, a photoelectrolysis cell based on multilayered TiO2/Ni/CuO (M-cell) photoelectrode is prepared on ITO substrate (110 nm thick) using a multi-target direct current and radio-frequency magnetron sputtering technique in which Ni acts as [...]
