ORGANIC PHOTODIODE, SENSOR, CAMERA, AND ELECTRONIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17851775 titled 'ORGANIC PHOTODIODE, SENSOR, CAMERA, AND ELECTRONIC DEVICE
Simplified Explanation
The abstract describes an organic photodiode that has a reflective layer, a semi-transmissive layer, a photoelectric conversion layer with an organic light absorbing material, and a buffer layer. The photodiode is designed to have three external quantum efficiency (EQE) spectra in a wavelength range of 380 nm to 3000 nm, with each spectrum having a full width at half maximum of 2 nm to 100 nm.
- The organic photodiode has a first electrode with a reflective layer and a second electrode with a semi-transmissive layer.
- A photoelectric conversion layer, containing an organic light absorbing material, is placed between the first and second electrodes.
- A buffer layer is included either between the reflective layer and the photoelectric conversion layer or between the semi-transmissive layer and the photoelectric conversion layer.
- The organic photodiode exhibits three EQE spectra in the wavelength range of 380 nm to 3000 nm.
- Each EQE spectrum has a full width at half maximum of 2 nm to 100 nm.

Original Abstract Submitted
An organic photodiode includes a first electrode including a reflective layer, a second electrode including a semi-transmissive layer, a photoelectric conversion layer between the first electrode and the second electrode and including an organic light absorbing material, and a buffer layer that is at least one of between the reflective layer and the photoelectric conversion layer or between the semi-transmissive layer and the photoelectric conversion layer. The organic photodiode is configured to exhibit at least three external quantum efficiency (EQE) spectra in a wavelength region of about 380 nm to about 3000 nm and each EQE spectrum of the at least three EQE spectra has a full width at half maximum of about 2 nm to about 100 nm.
