Technology
To understand the importance of String Ribbon technology is to grasp the elegant balance it strikes between conventional and emerging technologies.
Simple
String Ribbon combines the best attributes of conventional crystalline silicon
and emerging thin films. It achieves the reliability, stability, high efficiency,
and market acceptance of crystalline silicon - without the inherent cost and
waste of sawing. And it embodies the efficient material utilization and potential
for continuous processing of thin films, but with a more manufacturable process.
Reliable In the String Ribbon technique, two high temperature strings are pulled vertically through a shallow silicon melt, and the molten silicon spans and freezes between the strings. The process is continuous: long strings are unwound from spools; the melt is replenished; and the silicon ribbon is cut to length for further processing, without interrupting growth. This advantage in material efficiency means String Ribbon yields over twice as many solar cells per pound of silicon as conventional methods. Additionally, the resulting distinctive shape of the solar cell allows for a high packing density.
Advanced Ongoing technology development shows great promise for even lower cost. Early experiments have produced 15% solar cells on thin 100 micron wafers. And downstream, in cells and modules, Evergreen Solar is developing processes that are simple, continuous, non-vacuum, high throughput, environmentally benign, and energy efficient.
