“…The PET substrates will deform during high-temperature treatment and the electrodes on the substrates will be destroyed at the same time (Figure 10a, b) [127]. Compared with PET and PEN substrates, PES is optically clearer and has higher T g (223 °C) [128]. However, high cost and poor solvent resistance limit its practical applications [129].…”

Organic solar cells (OSCs) have gained a rapid development in the past two decades and the power conversion efficiency (PCE) of single-junction OSC has recently approached 20%. The novel materials and device engineering are two key factors of this evolution. In this review, the device engineering, including morphology characterization and optimization, device physics, flexible and large-area OSCs, and stability of OSCs are systematically summarized. In addition, the current challenges, problems and future developments are also discussed.

“…The mechanical strength, high transmittance and variable haze properties are among the key properties of such substrates that ensures its eligibility for various optoelectronics. [ 1 ] To name a few; 1) coating LED (light emitting diode) light with hazy film is the solution to eliminate the directivity issue of the LED light. [ 2 ] 2) Substrates with haze characteristics of 40% or above express antiglare properties when coated on screens.…”

Light‐management films made entirely from natural polymers with tunable haze properties are developed via a facile approach. A novel green method based simply on the blending of network cellulose (NC)/water suspension with alginate (CaAlg) aqueous solution is proposed. The unique NC suspension created by a controlled hydrolysis of microcrystalline cellulose acts as the scatterer media while alginate serves as the transparent host matrix. NC features isotropic intertwined network of nanofibers that contributes to light scattering and produces optical haze. The opaque but hazy NC is dispersed purposefully in the alginate film, where its original properties are preserved owing to its poor solubility in water. Additionally, the dispersion notably increases the roughness of the composite film surface and acts as a light scatterer. Eventually, composite CaAlg/NC film with high transparency (>94%) and customized haze (15–73%) at 550 cm−1 wavelength is fabricated. Herein, the transparent alginate is successfully combined with the hazy cellulose of uniformly distributed nanofibers by blending to fabricate transparent/hazy all‐natural films. The fabricated films exhibit high transparency with tailored transmission haze. The film is highly fitting for large‐scale production and adequate to meet different haze requirements to accommodate different applications such as privacy protection films and antiglare/antireflection coatings.

“…For this reason, intensive studies are carried out on the development of optoelectronic devices. In recent years, various optoelectronic devices with innovative materials have been reported Asare et al, 2020). Graphene is also one of those innovative materials and it is defined as the material made of a single layer of carbon atoms distributed in the vertexes of a hexagonal network (Daş et al, 2016;Choi et al, 2020).…”

Graphene is thought to be an outstanding material for novel photoelectrical devices due to its unique properties. However, because of the atomic thickness of the interaction lenght between graphene and light, the performance of graphene-based photoelectrical devices is limited. Therefore, in this presented study, graphene derivatives such as graphene oxide (GO) and reduced graphene oxide (rGO) were used instead of graphene to enhance the light absorption for metal-interlayer-semiconductor type Schottky heterojunction fabrication. Firstly, GO synthesis was made by the modified Hummer method, then rGO synthesis was carried out via the chemical reduction method by using L-ascorbic acid (LAA) as a reducing agent. The surface morphology, chemical compositions and optical properties of the synthesized materials were characterized using SEM-EDS, and UV-Vis-NIR spectrophotometer analyses. Subsequently, GO/n-Si and rGO/n-Si heterojunction device fabrications were made by using the spin coating method. The main junction parameters of the fabricated devices were determined using current-voltage (I-V) measurements. The obtained results indicate that the rGO thin film layer has a significant impact on the I-V characteristics due to its improved characteristics compared to the GO thin film. For this reason, I-V measurements of the rGO/n-Si heterojunction device were have been investigated as a function of temperature. The results revealed that the ideality factor (n), and series resistance (Rs) increased by the decreasing temperature while the barrier height (Φb) decreases. Furthermore, I-V measurements of the rGO/n-Si heterojunction device were performed under light illumination at room temperature. The obtained results showed that the synthesized rGO material can be used in optoelectronic applications such as photodiodes and photodetectors.
