A photovoltaic cell can include a dopant in contact with a semiconductor layer.

A drum dampening device includes a foam pad adapted to be selectively engageable with drum wires on the drum. The foam pad is configured to dampen vibrations of the drum wires when the foam pad is engaged with the drum wires. A support plate is coupled to the foam pad, and a base plate is coupled to the support plate. An adjustment lever is coupled to the support plate and the base plate. The adjustment lever is selectively transitional between a first position and a second position, with transition of the adjustment lever from the first position toward the second position causing at least a portion of the support plate to move away from the base plate resulting in engagement of the foam pad with the drum wires.
