“…[111] Transparent electrodes with low absorptance in the NIR-IR part of the spectrum (transparent electrodes with low FCA) are required for CIGS, SHJ and multi-junction devices, such as perovskite-onsilicon [109,112] and perovskite-on-CIGS [113] tandem solar cells, as these devices employ optical absorbers that are active in this range of the spectrum. These tandem approaches are new highefficiency photovoltaic technologies, with a potential to reach about 30% efficiency, [114,115] clearly underscoring the critical importance and urgency of designing transparent electrodes with exceptionally large broadband transparency.…”

With the development of new generations of optoelectronic devices that combine high performance and novel functionalities (e.g., flexibility/bendability, adaptability, semi or full transparency), several classes of transparent electrodes have been developed in recent years. These range from optimized transparent conductive oxides (TCOs), which are historically the most commonly used transparent electrodes, to new electrodes made from nano‐ and 2D materials (e.g., metal nanowire networks and graphene), and to hybrid electrodes that integrate TCOs or dielectrics with nanowires, metal grids, or ultrathin metal films. Here, the most relevant transparent electrodes developed to date are introduced, their fundamental properties are described, and their materials are classified according to specific application requirements in high efficiency solar cells and flexible organic light‐emitting diodes (OLEDs). This information serves as a guideline for selecting and developing appropriate transparent electrodes according to intended application requirements and functionality.

“…24 These studies are generally not self-consistent; they rely only on detailed optical modeling. The conclusions based on carrier transport modelled by simple one-diode compact model may not be definitive, at least in the case of a-Si/c-Si heterojunction solar cells.…”

As single junction thin-film technologies, both Si heterojunction (HIT) and Perovskite based solar cells promise high efficiencies at low cost. One expects that a tandem cell design with these cells connected in series will improve the efficiency further. Using a self-consistent numerical modeling of optical and transport characteristics, however, we find that a traditional series connected tandem design suffers from low due to band-gap mismatch and current matching constraints. It requires careful thickness optimization of Perovskite to achieve any noticeable efficiency gain. Specifically, a traditional tandem cell with state-of-the-art HIT () and Perovskite ( ) sub-cells provides only a modest tandem efficiency of 25%. Instead, we demonstrate that a bifacial HIT/Perovskite tandem design decouples the optoelectronic constraints and provides an innovative path for extraordinary efficiencies. In the bifacial configuration, the same state-of the-art sub-cells achieve a normalized output of =33%, exceeding the bifacial HIT performance at practical albedo reflections. Unlike the traditional design, this bifacial design is relatively insensitive to Perovskite thickness variations, which may translate to simpler manufacture and higher yield.

“…It should be also noted here that the highest efficiency for our perovskite tandem solar cells (around 25 %) is below Shockley-Queisser efficiency limit, which was however realized in some calculations [17][18][19][20][21][22] . The main underlying reason is that different electrical models and parameters are applied.…”
