OVERVIEW AND RESULTS OF THE GERMAN RESEARCH NETWORK PROJECT ASIS (ALTERNATIVE SILICON FOR SOLAR CELLS)

摘要

The photovoltaic research network project ASiS (Alternative Silicon for Solar Cells) was a joint venture of eleven German research institutes and three German PV-producing companies in the area of crystalline silicon material for solar cells. From October 2002 to December 2005, about 40 persons (listed below) were collaborating in the project ASiS. The main topics of ASiS were investigations of the photovoltaic potential of alternative silicon material (e.g. Phosphorus-doped n-type silicon and off-spec silicon), mechanical behaviour of crystalline silicon wafers and development of fast solar cell processes (e.g. Rapid Thermal Processing (RTP)). Examples of experimental results of the research institutes are given in this paper. Details can be found in specific contributions of the ASiS partners in various publications cited here [3 - 13]. It is planned to continue the joint research in a modified form as the SolarFocus project.
