Sharp has the speed vnom efficiency of a prototype solar cell is increased to 36.9 percent. The manufacturer reached the rate by the resistance between the three layers where the cells are built up to reduce. How that works exactly, is unclear.
The solar cells are composed of several photovoltaic layers containing two or more elements such as indium and gallium. Because of their greater efficiency, this type of compound solar cells, in particular in satellites applied.
Sharp claims that the resistance between the three different layers has been able to reduce, without going into detail how this is achieved. The percentage of 36.9 percent would be a record. Improving the efficiency with small steps. In 2009 did Sharp even though an improved conversion. When the company achieved with the same photovoltaic layers, and a yield of nearly 35.8 percent.
