“…The effect of neutron radiation on optoelectronic devices, solar panels, photodiodes and phototransistors has been observed in this experiment and published in International Journal of Photoenergy [6] and FME Transactions [4]. Nikolić at all [4,6] confirm that, according to current theories, neutron irradiation in all samples caused degradation of their structure and deterioration of the output characteristics ( Fig.…”

“…Degradation of the main parameters (I-V characteristics) of the optoelectronic devices and their improvement, as a consequence of annealing, was observed for all used samples and published in International Journal of Photoenergy [3] and FME Transactions [4]. Nikolić at all [3,4] confirm that gamma irradiation leads to degradation of the I-V characteristics and then annealing improves these characteristics ( Fig. 1 to 3.).…”

Due to its wide application areas, optoelectronicdevices are exposed, in their work enviroment, to different typesof radiation. Photodiodes, phototransistors and solar cells aremost common used optoelectronic devices. Therefore, a numberof experiments were performed on these devices in order toexplain their behavior in the environment with pronouncedgamma and neutron radiation. Especially when these two typesof radiation appear successively. This paper presents review ofthese researches and scientific papers based on them. A numberof PIN photodiodes, phototransistors and solar panels have beenexposed to gamma radiation, neutron radiation and, especially, totheir combination. Several types of photodiodes, phototransistorsand solar panels were used in the experiment. I-V characteristics(current dependance on voltage) and other output parametershave been measured before and after irradiation. Some unusualbehavior were observed.

“…In Figure d, we compare the stability of our perovskite devices with previous reports of crystalline silicon solar cells. Clearly, the radiation hardness of perovskite‐based device would be much better than silicon cells which retain only 61.2% of the initial PCE after irradiation by gamma‐rays with an accumulated dose of ≈2 Mrad …”

high-throughput fabrication of perovskite modules has also been demon strated with simple processes such as blade coating with module efficiency close to 15%. [8] It remains unclear as to whether the perovskite solar cells can operate over 25 years in a real-world environment that is filled with oxygen and moisture, which are their two major stressors. Enhanced encapsulation has clearly shown to elongate the operational lifetime of perovskite solar cells to a much longer duration, indicating that the intrinsic stability of perovskite solar cells may be much longer than expected. [9][10][11] Nevertheless, perovskite solar cells may find their niche applications in space where oxygen or moisture does not exist. For space applications, there are new stressors such as radiation that may impose new threats to the stability of perovskite solar cells, while stability of solar cells under radiation has been rarely studied. The increasing interest in perovskite-based X-ray and gamma-ray detectors warrants an imperative study of the stability of perovskite materials and devices under ionizing radiation. [12,13] Less than a handful of studies have been performed to reveal the effects of proton, electron, and X-ray irradiation on perovskite so far. [14][15][16][17] Miyazawa et al. irradiated perovskite solar cells with 1 MeV electrons and found that the devices retained 93% of their peak performance after irradiation with a fluence of 1 × 10 16 cm −2 . [15] Experiments conducted by Lang et. al. [14] indicated a decrease in short-circuit current density (J SC ) by 20% for perovskite solar cells exposed to a proton dose of 1 × 10 13 p cm −2 . The perovskite self-healed with recovery on fill factor (FF) and open-circuit voltage (V OC ) after the proton irradiation terminated. [16] The effects of soft X-ray exposure on uncovered perovskites were investigated by Motoki et al. who reported that soft X-ray irradiation resulted in the evaporation of perovskite surface with residual elements in the form of crystalline PbI 2 . Apart from above stability studies with different radiation sources, the stability of perovskite device under gamma-ray radiation is also important but remained virtually unexplored. [18] Large amounts of gamma-rays are inevitably produced when the galactic cosmic rays, comprising mainly protons and alpha particles, undergo nuclear interactions with the constituent nuclei of the spacecraft, which poses a challenge to the perovskite materials for their long-term application in space. Moreover, organohalide perovskites also showed great Organohalide metal perovskites have emerged as promising semiconductor materials for use as space solar cells and radiation detectors. However, there is a lack of study of their stability under operational conditions. Here a stability study of perovskite solar cells under gamma-rays and visible light simultaneously is reported. The perovskite active layers are shown to retain 96.8% of their initial power conversion efficiency under continuous irradiation of gamma-rays and light for...

“…PIN photodiodes have a higher quantum efficiency over other current read-out sensors [15]. This infers that a higher fraction of the incident photon beam contributes to the photocurrent [14,36]. The PIN photodiode’s wide intrinsic region has high charge densities [37] that implies many charge carriers per photon that strikes this region [14].…”

Numerous instruments such as ionization chambers, hand-held and pocket dosimeters of various types, film badges, thermoluminescent dosimeters (TLDs) and optically stimulated luminescence dosimeters (OSLDs) are used to measure and monitor radiation in medical applications. Of recent, photonic devices have also been adopted. This article evaluates recent research and advancements in the applications of photonic devices in medical radiation detection primarily focusing on four types; photodiodes – including light-emitting diodes (LEDs), phototransistors—including metal oxide semiconductor field effect transistors (MOSFETs), photovoltaic sensors/solar cells, and charge coupled devices/charge metal oxide semiconductors (CCD/CMOS) cameras. A comprehensive analysis of the operating principles and recent technologies of these devices is performed. Further, critical evaluation and comparison of their benefits and limitations as dosimeters is done based on the available studies. Common factors barring photonic devices from being used as radiation detectors are also discussed; with suggestions on possible solutions to overcome these barriers. Finally, the potentials of these devices and the challenges of realizing their applications as quintessential dosimeters are highlighted for future research and improvements.
