In addition, energy payback times for the above three sequences are shown. The module manufacturing energy was partitioned two ways. In one way, the silicon reduction, silicon purification, sheet formation, cell fabrication, and encapsulation energies were found. In addition, the facility, equipment, processing matrial, and direct material lost-in-process energies were appropriated in junction formation processes and full module manufacturing sequences. A brief methodology accounting for the energy of silicon wafers lost-in-processing during cell manufacturing is described.

The influence of line shape on the effective voltage drop, which was treated before for the uniform width lines and the fully tapered lines, has now been generalized to include any taper. The potential merits of an oblique arrangement of the grid lines with respect to the bus lines are investigated. It is found that the arrangement of the grid lines normal to the bus lines gives the best performance. However, the performance penalty for oblique arrangement at relatively small inclination angles against the normal to the bus line is rather small. Also, the ways of optimizing the front metallization pattern, consisting of grid and bus lines, with respect to lowest total performance loss, due both to shading by metal coverage and to voltage drops in the various elements of the current path, was re-investigated. It was determined that it is essential that each level in the hierarchy of conductors have a substantially lower sheet resistance, by at least an order of magnitude, than the preceding level. The findings of these analyses were combined into a set of Design Rules for the front metallization design for large area solar cells. (WHK).
