RESULTS

Analysis of four cases was done with the above factors to compare the costs between technologies, and to generate estimated costs of production. The four cases were:Case 1, Crystalline silicon: Case 2, Cast (Multicrystalline) silicon: Case 3, Ribbon silicon: and Case 4, Advanced (high efficiency (18%) concepts) silicon. While Cases 1 and 2 are clearly defined in present technologies, many assumptions had to be made for Cases 3 and 4. In particular Case 4 required many projections on equipment costs and throughput, and hence is meant to serve more as a potential scenario.

Table 3 gives a summary of the IPEG analysis for each case. The totals are broken down into various components, so that importance of different factors may be determined for each technology.
