“…Volmer–Weber growth mode occurs during the preparation progress of ultra‐thin metal films by physical deposition technology, also resulting in a rough surface and poor conductivity (as illustrated in the left picture of Figure 1f). Fan et al [ 43 ] deposited ultra‐thin gold electrodes on the photoresist/3 nm Ca hybrid modified layer with perfect performance of transmittance (78% at 550 nm), conductivity (14 Ω sq −1 ), and mechanical stability, which effectively inhibited the Volmer‐Weber growth mode, and the 7 nm gold film shows excellent smooth and continuous surface. To further increase the light transmittance of Ag within the diafiltration threshold, some research groups verified the outer optical coupling layer strategy, and introduced a cooling stage during the high‐speed evaporation of Ag, so that the diafiltration threshold was reduced to 6 nm, which greatly increased the light transmittance of the Ag electrode.…”

Semitransparent perovskite solar cells (ST‐PSCs) are highly promising for application in building‐integrating photovoltaics (BIPVs) due to their potential in tunable transparency and color. However, the comprehensive performance of ST‐PSCs falls quite short of the ideal requirements for BIPV. Herein, more attention is to review how to balance transparency and power conversion efficiency for ST‐PSCs. Optimizing transparent electrodes and the active layers are interesting strategies to achieve the transparency required by devices. In addition, to obtain color ST‐PSCs, tuning the bandgap of perovskite layers and designing the optical structure of the electrode are effective strategies. Last but not least, three significant optical evaluation indexes of ST‐PSCs are described in the supporting information: average visible transmittance, color rendering index, and light utilization efficiency.

One of the most widely used energy sources nowadays is nonrenewable, but the excessive consumption of these resources leads to environmental issues. Therefore, renewable energy sources have received much attention, including photovoltaic energy. A novel technology known as “third‐generation solar cells” is being studied, and in this class, the polymeric solar cells (PSCs) and the perovskite solar cells (PVSKs) can be highlighted. Several researchers are trying to find new ways to improve the energy conversion efficiency (PCE) and long‐term stability of these devices. In particular, PVSK has already demonstrated high PCE, but there is still a long way to go to develop more stable and better processable devices for large‐scale production. In the case of PSC, processability is a positive factor since its flexible films have great mechanical stability and can be processed in roll‐by‐roll systems. However, efficiency is still a challenge for researchers. Nevertheless, both types of devices are good alternatives for silicon cell substitution. However, further studies are needed to address the inherent problems of each device technology and move to large‐scale production.

The back electrode is an important factor affecting the performance of perovskite solar cells. In this paper, the effects of back electrode material, structure and thickness on the performance of perovskite solar cells are studied by using COMSOL software. It is found that compared with the work function of the back electrode metal, its resistance has small effect on solar cell performance. Besides the back electrode structures affecting cell performance, there are other factors affecting cell performance. In terms of the back electrodes with honeycomb structure, considering the difficulty in fabricating, the best cost performance occurs when the radius of the circle is approximately equal to the edge spacing. It is predicted that the cell performance will be improved by about 5% in porosity with increasing 10% in the back electrode. The resistance of the back electrode decreases with its thickness increasing. Considering the process and cost, the optimal thickness should be between 100 nm and 150 nm.
