Performance improvement of an upconversion device through optimized carrier injection balance

|
By Xiaoyu Wang, Lixiang Chen, Yanlian Lei, Zhoudao Wang
| Optica Verified
Enhancing carrier injection balance in near-infrared (NIR) to visible upconversion devices (UCDs) is crucial for improving efficiency and stability. This study presents the incorporation of an insulating polymer (polymethyl methacrylate (PMMA)) between an aluminum cathode and an electron transport layer to reduce excess electrons in a light-emitting layer, thus balancing electrode-injected electrons and NIR-generated holes.

Near-infrared and visible light dual-mode organic photodetectors

|

| Science Magazine Verified
Abstract We report a dual-mode organic photodetector (OPD) that has a trilayer visible light absorber/optical spacer/near-infrared (NIR) light absorber configuration. In the presence of NIR light, photocurrent is produced in the NIR light–absorbing layer due to the trap-assisted charge injection at the organic/cathode interface at a reverse bias.

UV to NIR Light Broadband Phototransistors Enabled by a Bi-layer Organo-metallic Halide Perovskite/NIR Light Absorbing Polymer Channel The high performing ultra violet (UV) to near infrared (NIR) light broadband phototransistors (PTs) are enabled by incorporating a bi-layer methylammonium lead triiodide (MAPbI3) perovskite/NIR light absorbing diketopyrrolopyrrole-dithienylthieno[3,2-b]thiophene (DPP-DTT) polymer channel.
