A system and method for applying an electrical bias to a photovoltaic device in a temperature control chamber, in which the temperature of the photovoltaic device is controlled according to a temperature profile. The temperature profile may include at least one hot phase and at least one cool phase.

In a first aspect, a method of manufacturing a substrate is provided wherein an end effector mounted substrate is attempted to be placed, that is put, onto a substrate support, such as a pedestal or slotted support of a substrate carrier, and the effectiveness of the put is verified by a sensor associated with the end effector. In one embodiment, the verification takes place during the retraction motion of the end effector and is accomplished by sensing the presence, absence, or location of the substrate on the substrate support. The sensor may be a through beam sensor, and may be mounted on, coupled to or otherwise move with the end effector adapted to carry the substrate. Numerous other aspects are described.

The present invention generally relates to an edge deletion module positioned within an automated solar cell fabrication line. The edge deletion module may include a grinding wheel device for removing material from edge regions of a solar cell device and cleaning the edge regions of the solar cell device after removing the material. The edge deletion module may also include an abrasive element, a portion of which is ground as it is periodically, laterally advanced toward the grinding wheel device. A controller is provided for controlling the operation and function of various facets of the module.
