“…Advantages of ECAs are their low-temperature processability (in a range between 120 °C and 160 °C), and reduced strain with substrates, compared to conventional soldering. 38,39 Nevertheless, many ECAs require curing at a temperature above 150 °C for several seconds to evaporate the binders. Again, in the context of perovskite compatibility the notion of low-temperature may thus require redefinition.…”

Over the last few years, perovskite solar cells have arisen as a technology to potentially side with mainstream silicon photovoltaics to help drive the transition towards renewable sources of energy. The coupling of perovskites with silicon in a tandem configuration may accelerate this development owing to the remarkably high power-conversion efficiencies possible with such devices. However, most of the perovskite/silicon tandem achievements so far have been confined to the lab environment, with only a few reported tests under outdoor conditions, using packaged devices. Nevertheless, one of the major challenges for perovskite/silicon tandem technologies, besides scale-up, lies in the cell-to-module (CTM) translation, which for the perovskite/silicon tandem concept is complicated by perovskite-imposed constrains such as a low temperature resilience, imposing challenges regarding tabbing and lamination, as well as a high sensitivity to moisture ingress, mandating the search for adequate encapsulation materials and methods. In this article, we describe and assess these challenges in depth and give a perspective on future directions towards module design, tailored for perovskite/silicon tandem photovoltaics, combining high performance with excellent durability. Our discussion also holds relevance for all-perovskite and other emerging photovoltaic technologies seeking market entry.

Over the past few years, perovskite solar cells have arisen as a technology to potentially side with mainstream silicon photovoltaics (PVs) to help drive the transition towards renewable sources of energy. The coupling of perovskites with silicon in a tandem configuration may accelerate this development due to the remarkably high power conversion efficiencies possible with such devices. However, most of the perovskite/silicon tandem achievements so far have been confined to the lab environment, with only a few reported tests under outdoor conditions, using packaged devices.

“…In addition, a shingled string circuit was formed by adding the resistance value of the ECA used for manufacturing the shingled string between each pair of interconnected cells. An ECA resistance value of 2.2 mΩ, obtained by varying the ECA resistance reported by Park et al [18], was used. (2) The modeled shingled string was connected in series and parallel, as shown in Figure 4.…”

Shingled photovoltaic (PV) modules with increased output have attracted growing interest compared to conventional PV modules. However, the area per unit solar cell of shingled PV modules is smaller because these modules are manufactured by dividing and bonding solar cells, which means that shingled PV modules can easily have inferior shading characteristics. Therefore, analysis of the extent to which the shadow affects the output loss is essential, and the circuit needs to be designed accordingly. In this study, the loss resulting from the shading of the shingled string used to manufacture the shingled module was analyzed using simulation. A divided cell was modeled using a double-diode model, and a shingled string was formed by connecting the cell in series. The shading pattern was simulated according to the shading ratio of the vertical and horizontal patterns, and in the case of the shingled string, greater losses occurred in the vertical direction than the horizontal direction. In addition, it was modularized and compared with a conventional PV module and a shingled PV module. The results confirmed that the shingled PV module delivered higher shading output than the conventional PV module in less shade, and the result of the shading characteristic simulation of the shingled PV module was confirmed to be accurate within an error of 1%.
