Hybrid perovskites, materials composed of metals and organic substances in their structure, have emerged as potential materials for the new generation of photovoltaic cells due to a unique combination of optical, excitonic and electrical properties. Inspired by sensitization techniques on TiO2 substrates (DSSC), CH3NH3PbBr3 and CH3NH3PbI3 perovskites were studied as a light-absorbing layer as well as an electron–hole pair generator. Photovoltaic cells based on per-ovskites have electron and hole transport layers (ETL and HTL, respectively), separated by an ac-tive layer composed of perovskite itself. Major advances subsequently came in the preparation methods of these devices and the development of different architectures, which resulted in an efficiency exceeding 23% in less than 10 years. Problems with stability are the main barrier to the large-scale production of hybrid perovskites. Partially or fully inorganic perovskites appear promising to circumvent the instability problem, among which the black perovskite phase CsPbI3 (α-CsPbI3) can be highlighted. In more advanced studies, a partial or total substitution of Pb by Ge, Sn, Sb, Bi, Cu or Ti is proposed to mitigate potential toxicity problems and maintain device efficiency.

“…[ 142 ] Currently, for screen‐printing method, the printing of all functional layers has basically been realized except for perovskite film, because the perovskite precursor solution based on organic solvents is not applicable to screen printing method. Alternatively, screen‐printed PSCs have been combined with various methods for preparing perovskite films have been introduced to fabricate screen‐printed PSCs, including slot‐die, [ 143 ] blade coating, [ 144 ] inkjet printing, [ 145 ] spray coating, [ 146 ] drop casting, [ 147 , 148 ] etc. Nevertheless, the realization of fully printed PSCs with screen‐printing of all functional layers is highly desired.…”

As a key contender in the field of photovoltaics, third‐generation thin‐film perovskite solar cells (PSCs) have gained significant research and investment interest due to their superior power conversion efficiency (PCE) and great potential for large‐scale production. For commercialization consideration, low‐cost and scalable fabrication is of primary importance for PSCs, and the development of the applicable film‐forming techniques that meet the above requirements plays a key role. Currently, large‐area perovskite films are mainly produced by printing techniques, such as slot‐die coating, inkjet printing, blade coating, and screen‐printing. Among these techniques, screen printing offers a high degree of functional layer compatibility, pattern design flexibility, and large‐scale ability, showing great promise. In this work, the advanced progress on applying screen‐printing technology in fabricating PSCs from technique fundamentals to practical applications is presented. The fundamentals of screen‐printing technique are introduced and the state‐of‐the‐art studies on screen‐printing different functional layers in PSCs and the control strategies to realize fully screen‐printed PSCs are summarized. Moreover, the current challenges and opportunities faced by screen‐printed perovskite devices are discussed. This work highlights the critical significance of high throughput screen‐printing technology in accelerating the commercialization course of PSCs products.
