Light Reflection Loss Reduction by Nano-Structured Gratings for Highly Efficient Next-Generation GaAs Solar Cells

Design and Analysis of Nano-Structured Gratings for Conversion Efficiency Improvement in GaAs Solar Cells

This paper presents the design and analysis of nano-structured gratings to improve the conversion efficiency in GaAs solar cells by reducing the light reflection losses. A finite-difference time domain (FDTD) simulation tool is used to design and simulate the light reflection losses of the subwavelength grating (SWG) structure in GaAs solar cells. The SWG structures perform as an excellent alte...

Nano-Structured Gratings for Improved Light Absorption Efficiency in Solar Cells

Due to the rising power demand and substantial interest in acquiring green energy from sunlight, there has been rapid development in the science and technology of photovoltaics (PV) in the last few decades. Furthermore, the synergy of the fields of metrology and fabrication has paved the way to acquire improved light collecting ability for solar cells. Based on recent studies, the performance o...

EXPLORING InAs/GaAs QUANTUM DOTS FOR NEXT GENERATION SOLAR CELLS

Nano-Structured Solar Cells

2.0 The resources at Arkansas are more than adequate. The team is very capable and can realize the stated goals. The results have shown that there is a chemical interaction between carbon nanotubes and P3HT. Solar panels based on carbon nanotube/P3HT organic materials were disappointingly low. Goals have been set to increase the efficiency. Some very preliminary results based on Si were given b...

Hierarchically structured nanotubes for highly efficient dye-sensitized solar cells.

Hierarchical TiO2 nanotube arrays grown on Ti foil are yielded by subjecting electrochemically anodized, vertically oriented TiO2 nanotube arrays to hydrothermal processing. The resulting DSSCs exhibit a significantly enhanced power conversion efficiency of 7.24%, which is a direct consequence of the synergy of higher dye loading, superior light-scattering ability, and fast electron transport.
