Abstract
Official abstract text for this publication.
A photodetector includes a substrate, an interdigital electrode layer and a photoactive layer. The interdigital electrode layer is located or sandwiched between the substrate and the photoactive layer. The interdigital electrode layer includes a first interdigital electrode and a second interdigital electrode. The first interdigital electrode and the second interdigital electrode are spaced from and staggered with each other.
First claim
Opening claim text (preview).
What is claimed is: 1. A photodetector comprising: a substrate, an interdigital electrode layer comprising a first interdigital electrode and a second interdigital electrode, wherein the first interdigital electrode and the second interdigital electrode are spaced from and staggered with each other; and a photoactive layer; wherein the interdigital electrode layer is sandwiched between the substrate and the photoactive layer, the first interdigital electrode comprises a first connection part and a plurality of first interdigital parts in connection with the first connection part, and the plurality of first interdigital parts are parallel with and spaced apart from each other; the second interdigital electrode comprises a second connection part and a plurality of second interdigital parts in connection with the second connection part, and the plurality of second interdigital parts are parallel with and spaced apart from each other; the plurality of first interdigital parts and the plurality of second interdigital parts are staggered and spaced apart from each other, a distance between adjacent one of the plurality of first interdigital parts and one of the plurality of the second interdigital parts is about 20 μm. 2. The photodetector of claim 1 , wherein a thickness of the interdigital electrode layer ranges from about 50 nm to about 150 nm. 3. The photodetector of claim 1 , wherein a material of the photoactive layer is CH 3 NH 3 PbI 3 . 4. The photodetector of claim 1 , wherein the interdigital electrode layer is 500×500 μm 2 square shaped.
