Rose petals for enhanced solar cells

Benjamin Li, Texas, USA 16-18

Worldwide, more than a billion people lack electricity. Another million lives suffer from emissions-linked respiratory ailments. In search of a renewable and inexpensive energy source, this project focuses on solar energy. Presently, the finest photovoltaic cells consist of crystalline silicon, gauged at 24% energy-conversion efficiency, which falls shorts of the 33.7% potential predicted by the Shockley-Queisser limit.

My study is the first to advance solar cell productivity with a superhydrophobic, anti-reflective, photoresistive coating using roses through the use of soft lithographic procedures. Ultimately, my novel PDMS-based transfer imprint process provides a high-fidelity, cost-effective method to reproduce functional structures from biomaterials.
