PV21Cell Technology Development
NPAC fundamental research activities concentrate on the development of CuInSe2 and related chalcopyrite thin film solar cells. NPAC is part of the EPSRC funded project "Photovoltaic Materials for the 21st Century" (PV21) with five other UK universities. Our research focuses on producing and characterising thin film cells based on Cu(In,Ga)Se2 materials by 2-stage processing. This includes deposition of metallic precursors by magnetron sputtering followed by selenisation at high temperature. Research is also undertaken into window and buffer materials. NPAC also operates the Photovoltaic Cell Test Facility, which enables measurement of single and multijunction solar cells. Assessment of the environmental impacts of production processes includes life cycle analysis and energy analysis (Athlet Project).
