The purpose of the invention is to provide a photoelectric conversion element enable to ensure the connection of the contact electrode easily and accurately. The cell connection piece includes an interconnect bus, a plurality of bus tabs unitarily formed with the interconnect bus, and a terminal bus coupled with the interconnect bus. The signal generators received in the sleeve are adapted to emit signals at a predetermined spacing from and in a predetermined alignment relative to the cross-bore wherein the retaining sleeve has recesses or through openings in its wall to accommodate the signal generators. In certain embodiments, a malware-infected hard drive image may then be copied off the malware analysis computing device.
