“…Deposition of protective coatings such as poly(methyl methacrylate) onto the perovskite can further enhance the device stability and efficiency. [28] Further optoelectronic measurements were conducted on these devices to gain an understanding of the underlying mechanism for the aforementioned observations. Following previous literature, TPV decay measurements were conducted to probe the charge recombination behavior.…”

PSCs) are based on an architecture in which the perovskite light-absorbing layer is positioned between several other functional layers. [3][4][5][6] As the performance of these perovskite "sandwich"-type devices approach their limit based on the device architecture, the shading effect associated with intrinsic parasitic light absorption and the low defect tolerance of the layered device architecture (e.g., pinhole-related shunting) become a significant barrier to further performance increases.To overcome the shading effect, an alternative device architecture can be employed in which the anode and cathode are both positioned underneath the perovskite light-absorbing layer. This back-contact concept is conventionally employed in siliconbased solar cells and has been adapted recently to PSCs. [7] With the light-absorbing layer being exposed directly to sunlight, shading effects encountered in the sandwich-type architecture are avoided. In addition to removing this parasitic light absorption, the back-contact architecture has the additional benefit of eliminating the need for costly transparent conductive oxide layers.As the performance of organic-inorganic halide perovskite solar cells approaches their practical limits, the use of back-contact architectures, which eliminate parasitic light absorption, provides an effective route toward higher device efficiencies. However, a poor understanding of the underlying device physics has limited further performance improvements. Here a mesoporous charge-transporting layer is introduced into quasi-interdigitated back-contact perovskite devices and the charge extraction behavior with an increased interfacial contact area is studied. The results show that the incorporation of a thin mesoporous titanium dioxide layer significantly shortens the chargetransfer lifetime and results in more efficient and balanced charge extraction dynamics. A high short-circuit current density of 21.3 mA cm -2 is achieved using a polycrystalline perovskite layer on a mesoscopic quasi-interdigitated back-contact electrode, a record for this type of device architecture.

“…[204,205] The fast-growing micro-nano processing technology enables the successful design and construction of various nano-patterns in photovoltaic devices, including micron-level pyramids, inverse opal structures, diffraction gratings, antireflective coatings, and other geometric structures. [204,206] Such nano-patterns have been proved to enhance the photon absorption and increase the device photocurrent. In QDSCs, by designing a submicron periodic photonic structure on the bottom electrode, the photon localization, or optical waveguide effect helps to increase the propagation distance of photons in the absorption layer.…”

“…This includes perovskite solar cells which reached a record high efficiency of over 25% (Cheng et al, 2014;Xie et al, 2018;Corzo et al, 2020;Lim et al, 2021b). In addition, recent studies have demonstrated that the use of various protective and antireflective coatings, such as intrinsic a-Si:H layers, among others, can considerably enhance the performance of future generations of thin film solar cells (Uzum et al, 2017;Zhao et al, 2017;Li et al, 2020a;Bacal et al, 2020;Qu et al, 2021). The scientific community devoted to semitransparent solar cell technology research may consider the recent advent of monolithic Perovskite/Si tandem solar cells as a unique opportunity to reshape the current knowledge in the field, allowing the possibility to reach the Shockley-Queisser theoretical efficiency limit of 33% (Ail-Ashouri et al, 2020;Lu et al, 2020).…”

Energy is the driving force behind the upcoming industrial revolution, characterized by connected devices and objects that will be perpetually supplied with energy. Moreover, the global massive energy consumption increase requires appropriate measures, such as the development of novel and improved renewable energy technologies for connecting remote areas to the grid. Considering the current prominent market share of unsustainable energy generation sources, inexhaustible and clean solar energy resources offer tremendous opportunities that, if optimally exploited, might considerably help to lessen the ever-growing pressure experienced on the grid nowadays. The R&D drive to develop and produce socio-economically viable solar cell technologies is currently realigning itself to manufacture advanced thin films deposition techniques for Photovoltaic solar cells. Typically, the quest for the wide space needed to deploy PV systems has driven scientists to design multifunctional nanostructured materials for semitransparent solar cells (STSCs) technologies that can fit in available household environmental and architectural spaces. Specifically, Plasma Enhanced Chemical Vapor Deposition (PECVD) technique demonstrated the ability to produce highly transparent coatings with the desired charge carrier mobility. The aim of the present article is to review the latest semi-transparent PV technologies that were impactful during the past decade with special emphasis on PECVD-related technologies. We finally draw some key recommendations for further technological improvements and sustainability.
