24 April 2017 Microlens-based light-trapping enhancement in perovskite solar cells (Conference Presentation)

We demonstrate experimentally-realizable microlens-based light trapping schemes for methyl ammonium lead iodide perovskite solar cells using rigorous scattering matrix simulations. Our simulations utilize commonly studied n-i-p device architecture where microlens array is coupled to the air-glass side of the solar cell. The microlens focuses light in the absorber layer that leads to increase in absorption and enhancement in photocurrent. Our optimal architecture has a period of ~700 nm and microlens height of ~800-1000 nm with absorption and photocurrent enhancement of ~6.5% and 6% respectively, for nearly lossless metal cathodes.
