| Energy harvesting generators are attractive as unlimited replacements for batteries in electronic devices and have been the focus of new researches for past years. This paper reviews the principles behind this technology and their integration to harvest energy. Also proposes a greener alternative for the production of quantum dots before the integration to new technologies. | Nanowires and Quantum Dots |
Energy Harvesting with Nanowires and Quantum Dots
Introduction
Harvesting energy is the core of our modern human existence. We need to power our cars, homes, and personal electronics. T o power our technology we need energy. Most electrical energy is harvested in one of two ways. These ways are mechanically harvested or harvested from solar power. Mechanically harvested energy needs moving parts, for example, to turn a generator. Solar energy can be harvested through solar cells via the photoelectric effect. As technology becomes smaller and more compact, power conversion technology needs to also adapt to this changes. Nanotechnology has shown great promise to become the power generator for future nanotechnology.1 That is the purpose of this paper to show how this technology works and is integrated to the production of energy. Nanowires have a diameter in between 20 nm and 100 nm. They can be made from many types of material, however most research is being done on silicon nanowires1-2 3 4 5 6 ; carbon and CdS/CdTe7 nanowires also are being researched. These nanowires can convert solar energy into electrical energy with enough efficiency to power small devices. This technology can create self sufficient nanotechnologies that do not need batteries or need to be connected to a power source. This new technology will be completely different to the macro-technology we have today, were we have to change out batteries or plug them into a wall. Self-sustaining technology is very green, because they do not
