摘要:
An LED substrate structure has a substrate and a conducting portion. The substrate has a bottom surface and two opposite first lateral surfaces connected with the bottom surface. The bottom surface has the conducting portion formed thereon, and the conducting portion has a first cutting segment located on a contact border defined between one of the two first lateral surfaces and the bottom surface. The conducting portion further has an expansion region connected with the first cutting segment. The length of the first cutting segment is shorter than any segment taken on the expansion region parallel thereto.
摘要:
An organic photosensitive optoelectronic device includes an anode, an organic photosensitive layer formed on the anode and having a donor portion and an acceptor portion, a hole blocking layer formed on the organic photosensitive layer so as for the organic photosensitive layer to be sandwiched between the anode and the hole blocking layer, and a cathode formed on the hole blocking layer so as for the hole blocking layer to be sandwiched between the cathode and the organic photosensitive layer. The highest occupied molecular orbitals (HOMO) of the hole blocking layer is at least 0.3 eV higher than that of the donor portion. Therefore, the optoelectronic device efficiently suppresses dark current so as to enhance sensitivity when applied to a detector.
