Vincenzo LaSalvia is a photovoltaics process engineer in the High Efficiency Monocrystalline Photovoltaics Group at NREL.
Vincenzo possesses a unique expertise in thermal and chemical processing of crystalline silicon wafers and solar cells. At NREL he has pioneered an investigation of defect generation and engineering in Czochralski-grown silicon through high-temperature annealing. In collaboration with Arizona State University and the Massachusetts Institute of Technology, he has studied this phenomenon’s effect on photocarrier lifetime evolution throughout the solar cell process.
Vincenzo is a key-contributor at NREL to demonstrating the fabrication of a 21.5% efficient silicon solar cell as well as the realization of a GaInP/Si dual-junction solar cells with 29.8% one-sun efficiency.
Vincenzo is also a co-inventor and U.S. patent recipient for his work concerning the Hydrogenation of Passivated Contacts. He has a background in device design and microfabrication, silicon epitaxy via chemical vapor deposition, and thin film processing and optical characterization. When not studying the photocarrier lifetime implications of intrinsic point defects in crystalline silicon, Vincenzo is an avid skier, mountain biker, alpine enthusiast, renewable energy advocate, and passionate audiophile.
