Distribution Status and Perspective of Photovoltaic Technology( I )

태양광발전 기술의 보급현황과 전망( I ) -일본, 미국, 유럽을 중심으로-

In recent years, the Photovoltaic(PV) industries have been Increasing steadily by an average of 30$\%$ per year. However, it is necessary to reduce PV module cost and to improve conversion efficiency to be promoted distribution of PV Japan, USA and Europe have been researching cost and efficiency of that. In this paper, we try to review diffusion status and policy of PV in these countries. From the results, we will intend to suggest a suitable future course for domestic PV distribution.
