Crystalline Technology and Manufacturing (CTM) Group European group of eight crystalline solar cell manufacturers (Q-Cells, Deutsche Cell, Bosch Solar Energy, Schott Solar, Sovello, Sunways, SolarWatt and Solland) is working together within SEMI in a pre-competitive environment to address the technology challenges facing the photovoltaic industry, and recognizes the need for standards. The priority of the CTM Group will be the definition of the development processes for raw materials, cell technology and cell manufacturing. The CTM Group has established a crystalline solar cell technology roadmap up to the year 2020 www.itrpv.net
