Internal Microlens Arrays Enhancing Performance of Dye Sensitized Solar Cells


Existing solar cell devices only control light outside of the device as a top-layer coating or solar collector. This invention from Lehigh University incorporates the lenses within the device itself. The microlens arrays redistribute the light internally and increase the exposed surface area associated with the dye support.


This method for making structures results in a device which has enhanced performance for dye sensitized solar cells. These structures have shown to increase the overall device performance by as much as 50%. In addition it allows for effectiveness in low-light conditions, is less fragile than Si solar cells and more light-weight and flexible. This invention offers the potential for lower cost solar cells and other applications include use in light emitting diodes.

The solar energy market has been growing 30% annually for the past 20 years with the industry reaching $96.8 billion by 2014. Installations grew 20% from 2009-2010 and will continue to increase as on-grid and off-grid installations become more common. There is large amount of enthusiasm for green energy, particularly in solar, and sunlight conditions have increased the sunlight levels allowing solar panels to increase power production. Demand has also increased infrastructure development to support solar energy. [1]
