“…withstanding processing temperatures over 600 °C and a WVTR below detection limits (3×10 -7 gm m -2 day -1 ), 13 but also offers a good flexibility with minimum bending radius of less than 100 mm, benefiting from its small thickness, typically 100 µm. 14 The ultra-thin glass also enables the manufacturing of lightweight PV modules, fulfilling requirements in emerging markets such as portable power supplies and electric vehicles which need solar panels to be as light as possible. Moreover, the flexible glass is compatible with roll-to-roll fabrication processing, where scalable solution coating strategies such as blade coating and slot-die coating can be applied to realize high throughput and high-speed manufacturing.…”

Perovskite materials are good candidates for flexible photovoltaic applications due to their strong absorption and low-temperature processing, but efficient flexible perovskite modules have not been realized yet. Here, we demonstrate a record efficiency flexible perovskite solar module by blade coating high-quality perovskite films on flexible Corning® Willow® Glass using additive engineering. Ammonium chloride (NH 4 Cl) is added into perovskite precursor solution to retard the nucleation which prevents forming voids at the interface of perovskite and glass. The addition of NH 4 Cl also suppresses the formation of PbI 2 reduces the trap density in the perovskite films. The implementation of NH 4 Cl enabled fabricating single junction flexible perovskite solar devices with an efficiency of 19.72% on the small area cells and a record aperture efficiency of 15.86% on the modules with an area of 42.9 cm 2. This work provides a simple way to scale up high-efficiency flexible perovskite modules for various applications.

“…When the thickness of the glass is reduced to a certain degree, it will have a certain degree of bending flexibility, so it can be used as a flexible substrate. [49,50] For example, Fan's group controlled the glass thickness to ≈50 microns to obtain flexible glass for the first time. [51] After 200 cycles of bending with a bending diameter of 4 cm, the power conversion efficiency (PCE) of the PSC was reduced from 11.7% to 11.24%.…”

Metal halide perovskite materials have excellent photoelectric properties, including high absorption coefficient, long charge carrier diffusion length, and low exciton binding energy, making them excellent candidates for photoconversion devices. In the past decade, great progress has been made in improving the performance of perovskite-based solar cells and photodetectors. However, perovskite devices need to be endowed with more functionality to meet practical application requirements. In this regard, the three major trends in perovskite device development involving flexibility, transparency, and self-healing have attracted wide interests. This review first summarizes the fundamental design principles of endowing perovskite devices with more functionality. Specifically, the functionalization is realized through elaborate substrate and electrode selection, perovskite layer modification, and device layout. This review presents the recent advances and specific requirements for functionalization of perovskite devices according to the three basic components: substrate, electrode, and perovskite layer. Finally, potential challenges and future research directions in this field are outlined. The aim of this review is not only to shed light on the basic design principles of functionalized perovskite devices, but also to serve as the roadmap for future exploration in perovskite devices.

What Is Driving the Growth of Inorganic Glass in Smart Materials and Opto-Electronic Devices?

Inorganic glass is a transparent functional material and one of the few materials that keeps leading innovation. In the last decades, inorganic glass was integrated into opto-electronic devices such as optical fibers, semiconductors, solar cells, transparent photovoltaic devices, or photonic crystals and in smart materials applications such as environmental, pharmaceutical, and medical sensors, reinforcing its influence as an essential material and providing potential growth opportunities for the market. Moreover, inorganic glass is the only material that is 100% recyclable and can incorporate other industrial offscourings and/or residues to be used as raw materials. Over time, inorganic glass experienced an extensive range of fabrication techniques, from traditional melting-quenching (with an immense diversity of protocols) to chemical vapor deposition (CVD), physical vapor deposition (PVD), and wet chemistry routes as sol-gel and solvothermal processes. Additive manufacturing (AM) was recently added to the list. Bulks (3D), thin/thick films (2D), flexible glass (2D), powders (2D), fibers (1D), and nanoparticles (NPs) (0D) are examples of possible inorganic glass architectures able to integrate smart materials and opto-electronic devices, leading to added-value products in a wide range of markets. In this review, selected examples of inorganic glasses in areas such as: (i) magnetic glass materials, (ii) solar cells and transparent photovoltaic devices, (iii) photonic crystal, and (iv) smart materials are presented and discussed.
