Norwegian business and British universities, "found that 4 of the working principle of generation of solar cells"

On August 2010,10,EnSol AS of Norway and the United Kingdom University of Leicester (University of Leicester)announcement, "found the 4th generation of solar cells and related to the basic principles." The principle can be achieved very high conversion efficiency, and potentially low-cost solar cells. EnSol said the aim of practical use in 2016.

This is a diameter of 10 ~ 100nm to the "nano-particles" mixed with a transparent medium, and coating the glass base plate made of a thin layer of thin film solar cells. It is reported that nano-particles by apple ibook g3 14-inch battery, it will release a "hot-electron (Hot Electron)" and produce EMF. This solar cell with infrared wavelengths than 2μm can be used to generate electricity, and compared to existing silicone solar cells can improve the energy conversion performance.

University of Leicester Department of Physics and Astronomy Professor Chris said, "As long as the surface is smooth, materials such as glass windows and the building can be anywhere such as painting walls, make it into a solar cell," so with the commercial power phase ratio, is expected to significantly reduce the cost of electricity. As the active layer is very thin, it is also possible to ensure transparency of the "power windows."

EnSol company The composition of nanoparticles are not public. However, the University of Leicester Professor Binns accept the "Nikkei Electronics," an interview said the "nano-particles are not (known as quantum dots) GaAs and other semiconductor particles, but the metal particles, surface plasmon resonance can be (SPR) effect for the electronic release. "

Recently, the use of SPR the relevant papers of solar cells increased dramatically. However, most of the technology will be used to increase electricity generation SPR absorption of sunlight, or expand the width of the wavelength range. The technology and differences in the past is that SPR effect in the dell inspiron 9100 battery of nanoparticles at the same time, but also as a charge source of supply.

Incidentally, in most cases, the first one on behalf of the solar cell pool is crystal silicon solar cell type, 2 generation refers to the thin film solar cells means the 3rd generation multi-quantum dot solar cells. The reason why the solar cells will be referred to as "4th generation" because their position is after the next generation of quantum dot-based solar cells.

EnSol company and division of the University of Leicester, Leicester University, responsible for the development and supply of nano-particles, EnSol the manufacture of battery cells using nanoparticles. Although there can only be stacked in a vacuum device manufacturing small units of various acer lc.btp03.001 battery, but in the near future, the company will import the glass floor of the larger manufacturing units 4cm square device. EnSol said, "The current objective is to achieve 20% conversion efficiency."
