Isorg and Raynergy Tek Join Forces to Develop Organic Photodetectors for Consumer Electronics Market

This collaboration marks an important step towards advancing OPD SWIR technology to launch next generation products

Isorg, a pioneer in Organic PhotoDetectors (OPDs) and large area image sensors, and Raynergy Tek, a leader in organic semiconductor announce the signature of a Joint Development Agreement to accelerate the development of OPD technology for short-wave infrared (SWIR) image sensors and detectors, which can be applied on next-generation biometric authentication on consumer electronics products.

According to Yole Group, an expert in the analysis of technology markets, the SWIR image sensor value market is expected to reach $2.9 billion by 2028, as SWIR imaging provides more detailed information than visible and near-infrared lighting. The existing silicon-based CMOS image sensors have no spectral response to SWIR light, and alternative inorganic semiconductors, such as InGaAs are too expensive to be integrated into consumer electronics products.

On the contrary, organic semiconductors can achieve SWIR light response by designing the molecular structure of polymers; this allows to create a photodetection layer using non-toxic and heavy-metal free materials with low-temperature, non-vacuum and fast processes, which bring more benefits than competing technologies.

This partnership is a major step forward for the development of OPD SWIR technology. Isorg has a strong technical background in OPD processes on different types of substrate including CMOS wafer, as well as device manufacturing, while Raynergy Tek is an expert in organic semiconductor materials: The combined focus of both companies will ensure the success of OPD technology in high volume applications in consumer electronics.

“We have been very active to develop evaluation platforms and application prototypes to address smartphones, VR headsets, healthcare and biometry applications. The collaboration with Raynergy Tek is an important activity to achieve the successful integration of SWIR based on OPD technology for next generation products” said Dieter May, CEO of Isorg.

Phoebe Tan, CEO of Raynergy Tek emphasized “we recently had a breakthrough in R&D, our proprietary materials showed remarkable SWIR response, the detectivity is up to 1011 Jones at 1300nm wavelength. The collaboration with Isorg is very important to demonstrate readiness and viability of our material for commercial development at fab level.”

Raynergy Tek’s Organic Semiconductors (OSCs) could participate in hydrogen generation! Our OSCs served as photocatalysts for visible-light-driven boosting efficiency and stability!

Photocatalytic water splitting for hydrogen and oxygen generation are seeing a new wave of interests as it allows converting solar energy into chemical energy, and membrane-based operations could offer the possibility to achieve one-step hydrogen generation from water splitting at ambient temperature without needing further energy inputs, contributing to a so called “clean Hydrogen Economy”. Therefore, the pursuit of innovative photocatalysts which can enhance the photocatalytic activity is imperative and continuously gain increased interests in R&D of Hydrogen generation.

In collaboration with Prof. Ho-Hsiu Chou from National Tsing Hua University, Prof. Chou successfully developed a hydrogen energy technology that utilizes Raynergy Tek’s proprietary conjugated polymer dots (Pdots) as organic photocatalysts, enhancing the efficiency and stability of photocatalytic hydrogen evolution, which is an encouraging R&D results to advance the large-scale hydrogen production. We are particularly proud that this specific work has been published in Macromolecules, December 2022. Excitingly, this work was selected as the Front Cover of Macromolecules in February 28, 2023 (Volume 56, Issue 4).

Raynergy Tek announces Novel Organic Semiconductors with spectral response of 1300 nm and detectivity of 1011 is within Reach !

We have achieved an important milestone in our Novel Organic semiconductor (OSCs) materials development. An OSCs material, PD-1300 which demonstrated good spectral response at wavelength of 1300 nm was developed by our R&D team successfully. The photodiode’s dark current density records an impressive value of 3x10-7 A/cm2 and detectivity tabulated to be 9.3 x 1010 Jones at voltage bias of -2 V, respectively, which to our knowledge is the best results of known reported for OPD-based SWIR device performance.

Generally, it is skeptical for organic semiconductor based photactive material to show spectral response of wavelength over 1000 nm, mainly attributed to the likelihood of recombinaton of the exciton generated by light within the ultra low bandgap material according to the known theoryof organic semiconductor. However, the prominent challenge was overcome by our materials designers and presents a strong candidate of materials for potential use in SWIR application. In addtional, the organic based photodiode device is made by solution, low temperature process and ink formulated using green solvent to be in line with low carbon emmision and ESG policy.

One of the key advantages of SWIR light is it can differentiate the objects which visible light cannot do, and offer better detectivity under objects due to higher transmmision. Therefore, the revolutionary SWIR image sensor is highly sought out and targeted to be widely adopted for under display 3D structuring for mobile phone authentication, eyes tracking for AR/VR headset, Lidar and camera for automotive ADAS or AD system etc. Besides, SWIR light is safer in operation for eye ball detection compared to that of NIR light, which make eye safety sensor a common future-sensor trend. As the latest market forecast from Yole Group, the SWIR image sensor might generate a value of $3.2B by 2027 with 52% CAGR since 2021.

This SWIR materials development project was started early this year, we are glad that the dedicated 10 months’ effort has significant results that could possibly propel us to next level materials innovation. We give the credit to our excellent R&D team led by Dr. Yi-Ming Chang (CTO), Dr. Chuang-Yi Liao (R&D director) and Dr. Kuen-Wei Tsai (R&D manager). We make science happen again! We will continue making it happen!

(b) Detectivity of PD-1300 device shows spectral response ranges from 300nm to 1500nm

We are proud to demonstrate a self-filter organic IR photodetector with proprietary materials achieves narrowband EQE of 53% with a narrow full width at half-maximum of 56 nm centering at 1080 nm, a highest performance ever reported in the organic IR photodetector technology.

A photoactive layer with narrowband IR spectral response is crucial for IR sensor, which can realize a color-filter free photodetector to avoid ambient light interference and impaired EQE by color-filter.

By applying charge collection narrowing technique with optimization of donor-acceptor stoichiometry, film thickness and transparent electrode, a top-illuminated self-filter organic IR photodetector is made, to read more details please visit

Figure 1: OPD device with PD-Visible-P as the main photon absorber shows no changes on dark current (left) and EQE (right) after subject to 120mins of 220 degreeC heat treatment

Our latest solution processable Organic Semiconductor - PD-Visible-P shows highest Processing Temperature Tolerance up to 220 degreeC for more than 120mins!

One of the widely known weakness of Organic Materials is their thermal stability that makes it vulnerable to be integrated into typical wafer processing.

In Q1 2022, Our R&D group has intensively researched into Organic Semiconductor with high temperature tolerance above 200 degreeC which is the typical optical layer processing temperature in CMOS manufacturing processes or backend processes.

Today, we announce our latest proprietary OPD product named PD-Visible-P that have been tested to show zero degradation on EQE and dark current even after an aggressive device soaked in 220 degreeC for 120 minutes. This particular work demonstrates that organic semiconductors could be designed to withstand wafer processing temperature at the same conserve its QE> 50%@550nm.
