“…In conjunction with blade-coated charge transport layers, the champion perovskite solar cell that processed in ambient air using green solvents achieved power conversion efficiency up to 18.6%. [168] Here we list several key parameters that should be considered when choosing which method to use for upscaling as shown in Table S3, Supporting Information. These parameters will all contribute to the cost of fabricating perovskite-silicon tandem solar cells, taking into account the efficiency, processing speed, and handling of toxic solvents, etc.…”

accounts for only ≈3% of global electricity generation. [1] However, PV is experiencing an accelerated growth globally with >130 GW installed in 2020, an acceleration that should continue in the future to provide 20-30% of the global electricity on the 2050 horizon. [2] The key to materializing this ambitious goal is to reduce the cost of PV-generated electricity to make solar energy significantly cheaper than that produced by fossil fuels, and to promote the implementation of storage technologies. [3] Currently, the major cost component of a PV system stems from the balance-ofsystems (BOS). [4] The BOS refers to all the components of a PV system other than the solar module, including wiring, inverters, land, installation, labor, etc. With cell costs typically accounting for less than 20% of the total module cost (and module costs typically account for around 40% at the system level), [4,5] increasing power conversion efficiency at the cell and module level is the most efficient way to reduce the levelized cost of electricity (LCOE), provided this efficiency gain comes at affordable manufacturing costs. [6] Increasing the solar module efficiency is even more important for residential rooftops, facades, or other applications where This review focuses on monolithic 2-terminal perovskite-silicon tandem solar cells and discusses key scientific and technological challenges to address in view of an industrial implementation of this technology. The authors start by examining the different crystalline silicon (c-Si) technologies suitable for pairing with perovskites, followed by reviewing recent developments in the field of monolithic 2-terminal perovskite-silicon tandems. Factors limiting the power conversion efficiency of these tandem devices are then evaluated, before discussing pathways to achieve an efficiency of >32%, a value that small-scale devices will likely need to achieve to make tandems competitive. Aspects related to the upscaling of these device active areas to industryrelevant ones are reviewed, followed by a short discussion on module integration aspects. The review then focuses on stability issues, likely the most challenging task that will eventually determine the economic viability of this technology. The final part of this review discusses alternative monolithic perovskite-silicon tandem designs. Finally, key areas of research that should be addressed to bring this technology from the lab to the fab are highlighted.

Just over a decade, perovskite solar cells (PSCs) have been emerged as a next‐generation photovoltaic technology due to their skyrocketing power conversion efficiency (PCE), low cost, and easy manufacturing techniques compared to Si solar cells. Several methods and procedures have been developed to fabricate high‐quality perovskite films to improve the scalability and commercialize PSCs. Recently, several printing technologies such as blade‐coating, slot‐die coating, spray coating, flexographic printing, gravure printing, screen printing, and inkjet printing have been found to be very effective in controlling film formation and improving the PCE of over 21%. This review summarizes the intensive research efforts given for these printing techniques to scale up the perovskite films as well as the hole transport layer (HTL), the electron transport layer (ETL), and electrodes for PSCs. In the end, this review presents a description of the future research scope to overcome the challenges being faced in the printing techniques for the commercialization of PSCs.

Dopant‐free hole transport layers (HTLs) are crucial in enhancing perovskite solar cells (pero‐SCs). Nevertheless, conventional processing of these HTL materials involves using toxic solvents, which gives rise to substantial environmental concerns and renders them unsuitable for large‐scale industrial production. Consequently, there is a pressing need to develop dopant‐free HTL materials processed using green solvents to facilitate the production of high‐performance pero‐SCs. Recently, several strategies have been developed to simultaneously improve the solubility of these materials and regulate molecular stacking for high hole mobility. In this review, a comprehensive overview of the methodologies utilized in developing dopant‐free HTL materials processed from green solvents is provided. First, the study provides a brief overview of fundamental information about green solvents and Hansen solubility parameters, which can serve as a guideline for the molecular design of optimal HTL materials. Second, the intrinsic relationships between molecular structure, solubility in green solvents, molecular stacking, and device performance are discussed. Finally, conclusions and perspectives are presented along with the rational design of highly efficient, stable, and green solvent‐processable dopant‐free HTL materials.
