According to the latest news: Recently, the Iowa State University and Ames lab found that the use of polymer solar cells bottom lines.
Studies have shown that this material layer has its own uniqueness. Even less than millionths of a meter in the undulating surface was also able to maintain uniform thickness, a thin, uniform layer of material and absorbance was making was bottom lines. Polymer photovoltaic cells can be obtained through these folds absorb more light – was included in the fold between the reflected light.
The cell surface was too light absorption was also able to maintain good electrical conductivity. The effective use of technology, light trapping device mechanism, the efficiency of photovoltaic cells can have increased by 20%.
Test also showed that compared with the flat photovoltaic cells, the edge of near-infrared spectrum of light increased nearly 100%. Folds have a much larger layer has a higher energy conversion efficiency obtained was space, which is captured by the light, especially longer wavelength photon capture efficiency was raised to cause too.
It is understood that the material can be widely used in conventional silicon-based photovoltaic cells, batteries and can improve the conversion rate of photovoltaic cells is a new revolution.
