A solar cell module and a method for manufacturing the same are discussed. Preferred calcium channel blockers are those compounds having high potency and bioavailability. The vias are positioned such that a plurality of vias are associated with each contact pad. In addition, a particular method and apparatus are disclosed in which electroporation andor mass transfer across a cell membrane are accomplished by securing a cell across an opening in a barrier between two chambers such that the cell closes the opening. The clutch is composed of a mechanical clutch section, and a solenoid coil for controlling the mechanical clutch section, and is a reverse actuation type clutch such that when the solenoid coil is in the energized state, the mechanical clutch section is in the disengaged state, while when the solenoid coil is in the de-energized state, the mechanical clutch section is in the engaged state.
