Scarpulla, Michael | Enhanced absorption in optically thin solar cells by scattering from embedded dielectric nanoparticles | Abstract: We present a concept for improving the efficiency of thin-film solar cells via scattering from dielectric particles. The particles are embedded directly within the semiconductor absorber material with sizes on the order of one wavelength. Importantly, this geometry is fully compatible wit... | 2010 | |

Scarpulla, Michael | Heat flow model for pulsed laser melting and rapid solidification of ion implanted GaAs | In order to further understand the pulsed-laser melting (PLM) of Mn and N implanted GaAs, which we have used to synthesize thin films of the ferromagnetic semiconductor Ga1−xMnxAs and the highly mismatched alloy GaNxAs1−x, we have simulated PLM of amorphous (a-) and crystalline (c-) GaAs. We pre... | 2010 | |

Scarpulla, Michael | Investigating sputtered Cu2Si1-xSnxS3 (CSTS) for earth abundant thin film photovoltaics | This study investigates the synthesis of chalcopyrite Cu2Si1-xSnxS3 (CSTS) thin films for photovoltaic solar cell absorber layers. Preliminary results indicate that layered sputtering of Cu, Sn, and Si followed by annealing in a sulfur atmosphere at 500⁰C does not provide adequate mixing or sulfu... | 2010 |
