Amorphous silicon PV panel mass production will require to mas ter plasma chemical deposition in terms of large sizes, cost, maintenance and all other problems related to industrialization. Since plasma deposition is a novel technique, the development of all this production related know how involves a considerable technical research effort. The major problems related to the design of a production deposi tion machine are the following - deposition should be uniform on very large area substrate (typical dimension 1 meter) ; - the deposited amorphous silicon should have good electronic properties (density of state of the order or less than 16 3 10 cm /eV) and very low impurities concentrations (for exam ple oxygen atomic concentration should idealy be less than 0. 01 %) ; - the film stress should be limited, the density of ponctual defects (particulates) should remain reasonable (less than 2 per 100 cm ) ; - dopant level control should be stable and efficient ; - silane consumption should remain reasonably efficient - financial cost being important the machine productivity should be high hence deposition rate optimized ; - downtime due to maintenance should be reduced to a minimum. We present here some results on the R&D effort addressed to the above mentioned problems. An original single chamber was designed. This machine will be made available on the market for R&D purposes by a process machine company. Finally the maintenance problem is considered. Plasma cleaning based on a fluorine containing etchant gases is studied and evaluated. 2. - Häftad, Engelska, 2011

This volume provides a valuable overview of the Commission's current activities in research on solar radiation data and in the development of solar energy applications in buildings. It contains the proceedings of the second contractors' co ordination meeting in the third four year R+D programme (1985-88) in these two fields, which was held in Brussels on 1 and 2 OCtober 1987. The first meeting was held on 13 and 14 November 1986. (') The research contractors' reports presented in this book give a full account of activities at an important stage in the programme where most projects have completed their preparatory stages and productive research is now fully underway. A feature of the reports is the pattern they illustrate of working groups in which practically all of the Member states are represented, co operating in the attainment of common goals within a co ordinated European programme. The meeting was attended by 60 participants and extended over two days. Presentations were made by the contractors on the objectives of their projects, progress made in the research, and future work plans and priorities. Each presentation was followed by a short d- cussion. The meeting was also important in improving communications between the research groups, exposing opportunities for co operation and collaboration, and monitoring progress. Among key achievements reported in the area 'Solar Radiation Data' is the implementation of a network of measuring stations at eight proto typical sites throughout Europe.
