サマリー

この調査レポートは、結晶シリコン系太陽電池と薄膜太陽電池、製造設備、原点となるポリシリコンの市場を分析しています。

Crystalline silicon is currently used in over 90% of PV cells. Despite the lower potential cost of emerging thin-film technologies (less material, higher theoretical efficiencies), crystalline silicon is expected to remain the dominant PV technology for at least the next 10 years due to its higher current average efficiency and its greater stability.

This report analyzes the market for both crystalline and thin film solar cells, equipment to make them, and polysilicon as a starting point. Marker shares of vendors in all these sectors are presented.
