Vincenzo LaSalvia

Researcher III-Materials and Process Engineering | 303-384-7300

Vincenzo LaSalvia is a silicon photovoltaics process engineer in NREL’s High-Efficiency Monocrystalline Photovoltaics Group with extensive 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 the Massachusetts Institute of Technology, he has studied this phenomenon’s effect on carrier-lifetime evolution throughout the cell process. Vincenzo is a key contributor at NREL in demonstrating the fabrication of a 21.5%-efficient silicon solar cell. He has a background in microfabrication and device design, silicon epitaxy via chemical vapor deposition, and thin-film processing and characterization.
