Provided are a wire electric discharge machining method for poorly conductive materials, such as solar cell silicon, and a semiconductor wafer manufacturing method and a solar battery cell manufacturing method based on the wire electric discharge machining method. In particular, the invention discloses a rapidly reprogrammable electronic time-temperature RFID tag that may be easily customized with the thermal time-temperature stability profile of an arbitrary material, using electronic data transfer methods. In another embodiment, the progressive level alert is presented on an affiliated or third party website.
