“…A research group from the University of Newcastle has demonstrated a pathway for ITO‐free fully R2R processed organic solar cells in a conventional geometry with a R2R sputtered aluminum top electrode . This shows that solution processable printing and coating methods can be combined with R2R vacuum techniques for the manufacturing of complete OPV modules …”

The production of electronic devices using solution based ("wet") deposition technologies has some decisive technical and commercial advantages compared to competing approaches like vacuum based ("dry") manufacturing. Particularly, the potential to scale up production processes to large areas and high volumes by introducing continuous roll-to-roll (R2R) methods on flexible substrates has been the topic of intense studies from both applied research institutes and industry already for some years. Decisive steps forward have been achieved during that time, resulting in the dawn of commercial applications for a number of processes, while additional development work is still needed in some other fields. This review summarizes the work published during the last few years on the R2R printing and wet coating of electronic devices. An overview is presented of the basic operational principles for the most commonly used R2R printing and coating methods and techniques for proper web handling in R2R lines. Then, the most commonly used types of flexible substrate materials are introduced, followed by a review of the work published in the application areas of transparent conductor materials, printed electric connections, light emitting devices, photovoltaic energy generation, printed logic, and sensing.

“…The broadband emission of these lamps is well suited to approximating the solar spectrum; however, large area solar simulation based upon these sources has proven both difficult and prohibitively costly . Consequently, there is an increasing need for low‐cost, large area solar simulation solutions driven by the ongoing transitioning of printed solar technologies from the laboratory to the commercial scale …”

A modular array of light emitting diodes of six different wavelengths is modelled and experimentally tested to provide Class AAA solar simulator illumination over an area of 20 cm2. The module demonstrates uniform distribution of light flux density across the sample test plane region, achieving Class A AM 1.5 G irradiance (100 mW/cm2) across the 400 to 1100‐nm wavelength range. The new system has a spectral match of 99.5%, a spatial non‐uniformity of 2.0%, and a temporal instability of <0.2%. The performance of the design (which will allow for large area simulators to be cheaply assembled from multiple modules) is then critically assessed in terms of the existing solar simulator standards and benchmarked against a conventional simulator.

“…This precise control of nanoscale morphology in multilayer OSC devices is typically achieved with various carefully calibrated laboratory fabrication and processing technique [33]. However, controlling the material nanoscale structure and morphology across large areas during the printing fabrication processes required for mass manufacture remains a significant challenge due to the crude thermodynamic levers available in the printing process [34]. In this article, we will provide an overview of the fundamental physics of OSC materials and then discuss their recent applications in radiation detection.…”

The deployment of organic semiconducting materials for radiation detection is an emerging and highly attractive area of materials science research. These organic materials offer the enticing vision of technologies created from low-cost materials that can be printed on-demand with a range of different tailored optoelectronic functionalities. An explosion in the number of available materials, improved functionality of materials, and sophistication of solution-based device fabrication techniques for organic semiconductors in recent years have led to considerable opportunities for the utilization of organic materials in the detection of ionizing radiation. While the potential of organic semiconducting materials for low-cost radiation detection is clear, transitioning these printable materials to a commercial reality presents a significant scientific challenge. In this work, we provide a comprehensive analysis of the use of organic semiconductors for radiation detection. We discuss the fundamental physics of these materials and how their conduction mechanisms, including charge generation and charge transport, differ significantly from established inorganic semiconductors. Various strategies employed to control the nanostructure in organic semiconductors to optimize charge generation and transport for radiation detection are discussed. We provide insights into the strategies employed to fabricate organic semiconducting devices at industrially relevant scales using roll-to-roll solution processing and finally discuss existing examples of organic semiconducting materials utilized in the radiation detection arena.
