Cost effective, high throughput ribbon-growth-on-substrate solar cell technology (RGSELLS)

Objective

For a fast development of photovoltaic, all links in the production chain of crystalline silicon solar modules must be improved. In this chain this proposal and a related Dutch project addresses a new way of wafer manufacturing (Dutch project) and solar cell process (this project). The technology that will be developed is based on the Ribbon-Growth-on-Substrate (RGS) silicon wafer technology (direct cast from a silicon melt). This technology, of which a proof-of-idea was demonstrated, has the characteristics of high throughput (1 wafer/second) and no Si material losses. Very promising solar cell efficiencies around 12.5% were demonstrated proving the high potential. What is needed and what is the objective of this project is the development of an RGS solar cell process with respect to throughput, costs and efficiency. The successful development of both the RGS wafer technology (Dutch project) and the solar cell process (this project) will reduce the costs of PV modules by at least 35%.
