Description: Das Projekt "Advanced solar cells and modules from multicrystalline silicon" wird vom Umweltbundesamt gefördert und von Universität Konstanz, Fakultät für Physik durchgeführt. General Information: The ASCEMUS project has been initiated by PV cell and system manufacturers (BP Solar, Eurosolare S.p.A and Shell Solar Energy) including the leading European research groups in the field of low cost solar cell processing (IMEC and University of Konstanz) and wafer manufacturer (Bayer AG). The main objective is to create the efficiency break-through of the industrial multicrystalline solar cells and modules produced in Europe. The project will start with the selection and testing of these laboratory solar cell processing steps which give the highest chances for a rapid improvement of the cost performance ratio. A compromise between the final cell efficiency and the capability for a low cost mass production will be emphasised. The ultimate goal is an integral, low cost, high efficiency solar cell process with well defined fabrication steps tested for implementation in the industrial environment. Apart from the solar cell process itself much attention will be paid to module fabrication since the process of integrating solar cells in a module, contributes with one third to the overall module cost. The expected technical achievements of the projects can be summarised: 1. Development of the wafering technique of larger area (up to 150 x 150 mm2) and thin (200 micrometers) multicrystalline silicon wafers. 2. Thorough testing and optimisation with respect towards implementation into mass production lines of the following, multicrystalline cell processing steps which are crucial for efficiency improvement - uniform texturization process: chemical, mechanical or plasma - high efficient emitter diffusion process: homogeneous and selective emitter - surface and bulk passivation by means of PECVD SiNx - fine line screen printing of contacts - light trapping 3. Combining the most efficient processing steps developed on laboratory and pilot line scale into an industrially compatible integral process: - simplification of the industrial solar cell process by incorporation of co-processing techniques - thorough test on the pilot and production line with respect to efficiency, reproducibility, spreading and through-put. 4. Development of new module type with a simplified manufacturing process and high packing density The quantified objectives of the project are summarised below: - cell efficiency from production line: 16 per cent (cell area 125 x 125 mm2). - best solar cell efficiency in a pre-production(pilot) line: 17 per cent - module power of 36 cells in series of 85 Wp(16 per cent efficient cell) and 90 Wp (17 per cent efficient cell) respectively. - cost target of 1 ECU/Wp within the APAS/MUSIC cost model (production scenario of 500MWp/year) ...
