Claim 19:
20. A test device, comprising a first electrode, an electron transport unit, a charge generation layer, a hole transport unit and a second electrode which are stacked; and
wherein the charge generation layer comprises an N-type doped layer and a P-type doped layer which are stacked, the N-type doped layer is adjacent to the electron transport unit, and the P-type doped layer is adjacent to the hole transport unit;
wherein the first electrode is an anode and the second electrode is a cathode, the charge generation layer is configured to generate a first internal current when a test voltage applied between the first electrode and the second electrode is a forward voltage, to allow drawing a voltage-current curve according to the first internal current varying with the forward voltage; or
wherein the first electrode is a cathode and the second electrode is an anode, the charge generation layer is configured to generate a second internal current when a test voltage applied between the first electrode and the second electrode is a reverse voltage, to allow drawing a voltage-current curve according to the second internal current varying with the reverse voltage.
