“…This type of glass is hermetic, highly transparent, dimensionally stable, impermeable to water molecules and suitable for high-temperature processing due to its low coefficient of thermal expansion (CTE) compared with foil and polymer substrates. 26 This unique property renders device a water repellent feature which not only can lead to a selfcleaning function in general, but also is potentially beneficial for device stability, since perovskite material can decompose in water quickly without proper passivation. 6,10 …”

Flexible thin film solar cells have attracted a great deal of attention as mobile power sources and key components for building-integrated photovoltaics, due to their light weight and flexible features in addition to compatibility with low-cost roll-to-roll fabrication processes. Among many thin film materials, organometallic perovskite materials are emerging as highly promising candidates for high efficiency thin film photovoltaics; however, the performance, scalability, and reliability of the flexible perovskite solar cells still have large room to improve. Herein, we report highly efficient, flexible perovskite solar cells fabricated on ultrathin flexible glasses. In such a device structure, the flexible glass substrate is highly transparent and robust, with low thermal expansion coefficient, and perovskite thin film was deposited with a thermal evaporation method that showed large-scale uniformity. In addition, a nanocone array antireflection film was attached to the front side of the glass substrate in order to improve the optical transmittance and to achieve a water-repelling effect at the same time. It was found that the fabricated solar cells have reasonable bendability, with 96% of the initial value remaining after 200 bending cycles, and the power conversion efficiency was improved from 12.06 to 13.14% by using the antireflection film, which also demonstrated excellent superhydrophobicity.

“…During the time of immersion, the alkali ions from the glass that are close enough to the surface are exchanged for those from the molten salt [3,4]. From the point of view of photovoltaic applications this type of glass is very popular as a substrate for the production of CdTe solar cells [5][6][7], CIGS solar cells [8] or perovskite based solar cells [9].…”

Chemically strengthened ultrathin glass with a thickness of less than 1 mm has many advantages, such as flexibility, smooth surface, good transmittance, excellent gas and water barrier, much higher toughened in relations to thermally tempered glass, higher impact resistance, increased corrosion resistance and much higher abrasion rate. Chemical strengthening process is a process where an ion exchange occurs by diffusion between the glass panes and the brine solution bath. The deeper penetration of the glass surface by ions contained in the brine bath contributes to the hardness of the glass sheets, which reduces the occurrence of surface defects that cause reflections. From the point of view of photovoltaic applications ultrathin glass significantly reduces the weight of the whole photovoltaic panel structure with respect to known solutions. Furthermore, the reduction of the glass thickness increases the transmission of solar energy in the visible range directly through the glass. In addition, chemical tempered glass has a lower reflectance of light from the surface than the thermally tempered glass. What is more, ultrathin glass is perfect substrate for deposition of nanomaterials, i.e. conductive films or quantum dots.In this work we demonstrate that chemically strengthened ultrathin glass is a perfect material for the photovoltaic applications, i.e. as a substrate for deposition of thin layers and for the design of photovoltaic modules of reduced weight.
