The Blue-Doped Wafer is an item added by the RedPower 2 mod. The Blue-Doped Wafer is used in the recipes for two out of the three types blutricity generators which currently exist within the mod, the Solar Panel and the Thermopile (the third being the Wooden Windmill & Wooden Wind Turbine). The Blue-Doped Wafer is also used to create the Light Sensor, a block which, if a sufficient amount of light falls upon it from the sky (either sunlight or moonlight) will emit a redstone signal. This is due to the Blue-Doped Wafer's naturally photosensitive properties, a property which makes it the operative component in RedPower Solar Panels.
