n addition to the current offer of Gleichmann Batteries with battery packs and desktop/plug-in charging solutions we are going to broaden our portfolio with Sanyo solar panels. We chose Sanyo as a partner who helps us to provide charging solutions with smaller up to medium energy needs without using any other power plugs.
Development of Solar TechnologyThe development of solar cells is taking place with a rapid speed. As a type of energy which uses the amazing power of sunlight efficiently, it offers a lot of potential to replace our current main power supply: fossil fuels. Solar energy is not only clean it is also an exhaustless energy source which offers electricity where ever and when ever sun light becomes available. |

Special Features of Amorphous Solar Cells
In general there are two types of silicon cells: crystalline and amorphous. At normal sunlight the efficiency factor of crystalline cells is higher but nevertheless amorphous cells contain not only less silicon which makes them being lighter they also have a couple more advantages over the crystalline type. A higher temperature range, a flexible panel construction in shape, voltage and current and that less energy is needed in production are some more positive aspects. Due to the reciprocal action between photons and silicon atoms, more light can be absorbed and a low light usage down to only 10 lux is still possible which allows using them also as a sun detector. Because of the lower need of raw material and by using metal or plastics as the substrate, flexible solar panels can be produced. As there is a demand for bendable panels too, we can already offer six of these film panels with a bend radius of 60 mm and 0.4 mm thickness in the standard portfolio. |
Layout of Amorphous Solar cells
At a p/n junction of two different semiconductor materials, the electrons are diffused in the n-type material and the positive holes are scattered in the p-type material. When sunlight reaches the p/n junction light energy gets converted into electricity and supplies power to an external load because of the voltage difference. Amorton is Sanyo’s amorphous solar cell series which uses silane (SiH4) as source gas and is fabricated using a plasma CVD method. The p-i-n layers are formed consecutively on a glass substrate. As a result of how the layers are formed, any desired voltage can be realised also without changing the panel shape. |
