ASCA and Raynergy Tek are strengthening their partnership

By using Raynergy Tek’s newest semiconductor materials, non-fullerene acceptor-based organic semiconductors and a new generation of hole transport layer, ASCA has achieved significantly higher OPV efficiency, beyond 70 watts per square meter while maintaining its durability. This is a 40 percent power increase compared to today’s industrial product.

In order to further improve and upscale with these materials, Raynergy Tek and ASCA are strengthening their long-lasting partnership through signing a Memorandum of Understanding.

On this occasion, an ASCA OPV structure, a concept of Zero-Energy Media Façade has been installed at Raynergy Tek’s new facility in Hsinchu Science Park, Taiwan.

We are very optimistic about the growth of OPV market and have common goal to bring theOPV business to next level.

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!

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

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.
