  • Duurzaamheid van fotovolta´sche systemen op basis van geavanceerde silicium technologie (in Dutch)
    Erik Alsema
    Public report, Universiteit Utrecht Copernicus Instituut Sectie Natuurwetenschap en Samenleving, ISBN 90-393-3581-8, January 2004
    In this report an environmental Life Cycle Assessment (LCA) is made of advanced production technologies for crystalline silicium modules in comparison with the existing production technology. Among the investigated technologies are Solsilc solar-grade silicium, Ribbon-Growth-on-Substrate and Edge-defined Film-fed Growth. Also an assessment is made of new solar inverter types and novel roof-integration concepts, like PV-wirefree. Based on these analyses potential improvements in the environmental profile of photovoltaic systems are evaluated. Also energy pay-back times and CO2 emissions of the considered PV systems are calculated. Finally options for technological improvement are presented.
