AltEnergyInfo: Startup company Twin Creeks’ ion cannon can make flexible silicon based solar cells at half the cost

The current way most manufacturers make silicon based solar cells is to take blocks of silicon and cut them into wafers 200 micrometers think. The cutting process ends up wasting about half of the silicon. Any thinner than 200 micrometers, and the wafers tend to get brittle. What Twin Creeks has developed allows them to make strong 20 micrometer think wafers with hardly any waste. By using their newly designed particle accelerator (the Hyperion 3 ion cannon), they bombard three millimeter thick disks of crystalline silicon with a high energy beam of hydrogen ions. When the wafer is heated, the
