Solar power with higher efficiency and lower costs to fossil fuel power generation to compete. Currently dominant in the field of silicon solar cells solar energy technology, but its high cost hinder the wide application of silicon-based solar cells.The use of inorganic nanocrystals or quantum dots solar cells cost less, but its conversion efficiency is not high enough.
Israel Institute of Technology researchers have developed a new method to generate the electric field in a quantum dot nanocrystals is more suitable for the production of energy-efficient solar cells.
Nature, Materials, October 9, 2009 report issued by the Israel Institute of Technology Nir Tessler professor in and colleagues describe how they are to adjust the electrical properties of quantum dots, and then test its performance in camiseta juventus fc the solar cell model.
Quantum dots are a very small size of semiconductor nanoparticles, and considerations based on quantum mechanics, can exist in the electron energy in the quantum dot is camiseta la galaxy very limited. Determined by the size of the quantum dot energy levels, in turn, also determines the energy gap. By controlling the size of quantum dots, you can easily adjust the width of the energy Inspiron 1545 battery?gap, without changing the material or production process. The quantum dot solar cells is an emerging field of solar cell research, the use of quantum dots as a photovoltaic material instead of silicon, CIGS thin or CdTe.
