“…Interaction with moisture and oxygen results in emanation of the organic species from the MAPbI 3 matrix, leaving it Pb-rich, thereby deteriorating the photo-response of these detectors 34 , 37 . Hermetic encapsulation is essential for the long-term functioning of these detectors and is still a crucial challenge for perovskite materials that are currently under development for different applications 34 , 38 . Several cation and anion doping schemes have been suggested to alleviate this stability problem and can be used to stabilize these X-ray detectors for long-term applications under ambient atmospheres 39 – 41 .…”

Large-area X-ray imaging is one of the most widely used imaging modalities that spans several scientific and technological fields. Currently, the direct X-ray conversion materials that are being commercially used for large-area (> 8 cm × 4 cm without tiling) flat panel applications, such as amorphous selenium (a-Se), have usable sensitivities of up to only 30 keV. Although there have been many promising candidates (such as polycrystalline HgI2 and CdTe), none of the semiconductors were able to assuage the requirement for high energy (> 40 keV) large-area X-ray imaging applications due to inadequate cost, manufacturability, and long-term performance metrics. In this study, we successfully demonstrate the potential of the hybrid Methylammonium lead iodide (MAPbI3) perovskite-based semiconductor detectors in satisfying all the requirements for its successful commercialization in synchrotron and medical imaging. This new generation of hybrid detectors demonstrates low dark current under electric fields needed for high sensitivity X-ray imaging applications. The detectors have a linear response to X-ray energy and applied bias, no polarization effects at a moderate bias, and signal stability over long usage durations. Also, these detectors have demonstrated a stable detection response under BNL’s National Synchrotron Light Source II (NSLS-II) 70 keV monochromatic synchrotron beamline.

“…An important application for PV technology was presented by Centeno et al, (2020) [31], showing a simple, low-temperature, low-cost, and scalable CL method (Figure 17a) to engineer parylene-C (poly(chloro-p-xylylene)) coatings with encapsulating properties that endow effective light-trapping (LT) and water-repelling functionality when applied in thin-film solar cells (Figure 17b-e). Parylene-C was used as the preferred coating material, as it is a polymer with excellent barrier properties for encapsulation [183,184] and low water-adhesion surface energy. It also benefits from optical transparency, adequate refractive index, outstanding flexibility, and mechanical strength.…”

The pursuit of ever-more efficient, reliable, and affordable solar cells has pushed the development of nano/micro-technological solutions capable of boosting photovoltaic (PV) performance without significantly increasing costs. One of the most relevant solutions is based on light management via photonic wavelength-sized structures, as these enable pronounced efficiency improvements by reducing reflection and by trapping the light inside the devices. Furthermore, optimized microstructured coatings allow self-cleaning functionality via effective water repulsion, which reduces the accumulation of dust and particles that cause shading. Nevertheless, when it comes to market deployment, nano/micro-patterning strategies can only find application in the PV industry if their integration does not require high additional costs or delays in high-throughput solar cell manufacturing. As such, colloidal lithography (CL) is considered the preferential structuring method for PV, as it is an inexpensive and highly scalable soft-patterning technique allowing nanoscopic precision over indefinitely large areas. Tuning specific parameters, such as the size of colloids, shape, monodispersity, and final arrangement, CL enables the production of various templates/masks for different purposes and applications. This review intends to compile several recent high-profile works on this subject and how they can influence the future of solar electricity.

“…Важнейшая среди них это деградация перовскитных СЭ под воздействием влажности, окисления, света, тепла и внешнего электрического поля [7][8][9][10][11][12][13][14][15]. Для борьбы с разрушающим эффектом влажности были предложены различные методики, такие как герметизация [16,17], модификация поверхности перовскитных пленок гидрофобным материалом, играющим роль слоя для переноса дырок [18]. Также, для повышения стабильности перовскитных пленок было предложено использовать внедрение в них полимерной компоненты, например полиэтиленгликоля [19].…”

It is shown that the introduction of a mixed cellulose esters with acetrimethyl acetate into films of organometallic perovskite CH3NH3PbBr3 significantly increases their stability while maintaining the optical and photoelectric properties of perovskite. It was found that with the introduction of 10-20 wt% mixed cellulose ester in CH3NH3PbBr3, the resistivity of the composite increases by 5-10 times within 60-70 days, while in pure perovskite films such changes are observed within 10-15 days. When the films are irradiated with a simulated sunlight, the resistance of the samples drops by 2-3 orders of magnitude, and the effect of photosensitivity persist for more than 2 months. The formation of hydrogen bonds between mixed cellulose ester and organometallic perovskite is, in our opinion, the main factor that increases the stability of the composite film in comparison with pure perovskite. The investigated composite films are promising for the design of degradation-resistant perovskite solar cells and light-emitting diodes.
