In this paper, we demonstrate multi-layer Silicon Nano-Particle (SNP) solar cells as a promising photon management technique in ultrathin photovoltaics. We show how this inherently textured architecture acts as a light absorber while having the potential to separate and transport photo-generated carriers.
Two main schemes are used 110: axial junctions 111, 112, in which the p–i–n diode is fabricated along the length of the nanowire by varying the doping density during growth; and radial junctions 113, in which the diode is fabricated coaxially by a core–shell method. The advantages of using silicon nanowires for solar cells are multifold.
Nanotechnology plays a pivotal role in improving the efficiency of solar cells. By incorporating nanomaterials, such as nanostructured silicon or titanium dioxide, the surface area of solar cells can be increased, allowing for more efficient light absorption.
The future of nanotechnology in solar cells is promising. Continued advancements in nanomaterials and fabrication techniques will likely lead to higher efficiency, lower costs, and increased adoption of solar energy. Nanotechnology holds the key to achieving sustainable and clean energy solutions, powering a greener future.
Indeed, Alivisatos hopes that within three years, Nanosys-a Palo Alto, CA, startup he cofounded-will roll out a nanorod solar cell that can produce energy with the efficiency of silicon-based systems. The prototype solar cells he has made so far consist of sheets of a nanorod-polymer composite just 200 nanometers thick.
