Solar Cell In subject area: Engineering A solar cell is a semiconductor device in which solar energy of certain wavelengths can be absorbed to generate free electrons (negative charges) on one side and holes (positive charges) on another. From: Smart Clothes and Wearable Technology, 2009 About...
The solar cell structure shown in Fig. 4.1 is the n/p configuration type. In summary, the solar cell is a p-n junction device having contacts on both sides with an antireflection coating on the front side. Solar cells work on the principle of photovoltaic effect. When photons from solar ...
根据首段中的“A solar cell works based on the photoelectric effect (光电效应), which happens when light interacts with a special light-absorbing material, known as a semiconductor (半导体).(太阳能电池的工作原理是光电效应,当光与一种特殊的光吸收材料(称为半导体)相互作用时,就会发生光电效应。)”...

If you put a small photovoltaic cell on top of a parking meter, an emergency telephone or a calculator, there is no need to be near an electricity supply. Photovoltaic cells are also used to operate satellites in space. There is a problem--they are expensive because they are made from si...
It works on the principle of convergence in which a high quantity of solar radiation is concentrated into a minor region or place where the PV cell is situated with the help of lenses and curved mirrors, which allows a reduction in the quantity of expensive semiconductor material. The degree ...
3.3.5Polymer photovoltaic cell Apolymer solar cellis a type of flexible solar cell made with polymers, large molecules with repeating structural units, that produce electricity from sunlight by thephotovoltaic effect.Polymer solar cellsincludeorganic solar cells(also called “plastic solar cells”). Th...
scientists have started to look for ways to reroute or otherwise capture some of that excess energy. While several methods are being investigated, Schmidt’s team has focused on using a molecule-thin layer of tetracene, another organic semiconductor material, as the top layer of a solar cell....
