A jig for a sample for a solar photovoltaic device is disclosed. The jig includes a cradle unit supporting the sample and a contact unit including at least one probe pin coming into contact with a busbar of the sample located in the cradle unit. The contact unit includes a coupling plate coupled with the cradle unit and at least one contact bar including a PCB and connected to the coupling plate, the contact bar having at least one probe pin aligned with the busbar of the sample with interposition of a probe pin connecting block. the jig includes a rotation support unit coupled with the cradle unit by a rotation shaft to allow the cradle unit to be rotated at an angle of 180&#xb0; or greater so that upper and lower surfaces of the sample supported by the cradle unit are reversed.
