Historical and Future Cost Dynamics of Photovoltaic Technology

摘要: A variety of factors, including government activities, have enabled a factor 700 reduction in the cost photovoltaics (PV) over past six decades. No single determinant predominantly explains improvement to date; R&D, economies scale, learning by doing, and knowledge spillovers from other technologies all played role reducing system costs. The observed reductions PV are due both incremental nonincremental technical improvements. Although policy models typically emphasized changes, this chapter describes prevalence changes. Informing important decisions related depends on development that reliably characterize types change.
