Twin Creeks Unwraps New Tool, Process to Slash Silicon Solar PV Costs | Renewable Energy News Article

Progressing further toward the goal of "grid parity" means continually refining all steps along the solar supply chain, from manufacturing to balance-of-systems. For silicon-based solar PV manufacturing, costs on the materials alone (silicon, process gases, silver paste, encapsulants, etc.) can be $0.60/Watt. One dollar per watt for solar, fully installed, is held up as the ultimate grid-parity goal — but that's still a long way off, and costs have to come down a lot more both in manufacturing and balance-of-systems. Some companies have figured the best way to reduce costs is by using less starting material. Today's conventional silicon-based solar PV manufacturing still means sawing silicon ingots into wafers 150 to 200 microns thick. This creates issues of kerf loss (material lost as sawdust) and wafer fragility, and requires the need to prep the new wafer's surface for ...
