Prospects and strategy for large scale utility applications of photovoltaic power systems

The paper reviews the status and prospects of photovoltaic power systems and the R and D trends (silicon performances, thin films, balance of systems components), and describes the market diffusion strategy for the application of PV systems: at the short and medium term level, isolated systems for rural electricity supply in IEA member countries and decentralized energy supply (remote users and village power) in developing countries; at the medium and long term level, decentralized building integration in urban and rural areas, power stations for peak power and local grid support. The objectives of the IEA collaboration programme launched among 18 industrialized countries are summarized, with particular reference to technology transfer to developing countries. 4 figs
