“…Thus, several research efforts have been made to fabricate low-temperature processed mesoporous PSCs and planar PSCs. [38][39][40][41] In addition, some other strategies such as interfacial engineering [42][43][44] and metal doping [45][46][47][48][49] have been employed to increase the PCE of the mesoporous PSCs. Similarly, for the conventional n-i-p structured mesoporous PSCs, SnO 2 scaffolds have been utilized as ETLs, which delivered a PCE of over 22%.…”

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.

“…% Nb into the compact TiO2 ETL produced higher PCE compared with the mesoporous TiO2 ETL, with 33.1% and 28.8% for the compact and mesoporous ETLs, respectively. The higher carrier injection with higher Nb incorporation efficiency produced during the addition of Nb to the TiO2 crystal structure provided a band gap reduction in the ETL, which gave more potential between the conduction band of the perovskite layer and the conduction band of the TiO2 ETL layer [93].…”

The electron transfer layer (ETL) plays a vital role in achieving high-performance perovskite solar cells (PSCs). Titanium dioxide (TiO2) is primarily utilised as the ETL since it is low-cost, chemically stable, and has the simplest thin-film preparation methods. However, TiO2 is not an ideal ETL because it leads to low conductivity, conduction band mismatch, and unfavourable electron mobility. In addition, the exposure of TiO2 to ultraviolet light induces the formation of oxygen vacancies at the surface. To overcome these issues, doping TiO2 with various metal ions is favourable to improve the surface structure properties and electronic properties. This review focuses on the bulk modification of TiO2 via doping with various metal ions concentrations to improve electrical and optical properties, charge carrier density, and interfacial electron–hole recombination, thus contributing to enhancing the power conversion efficiency (PCE) of the PSCs.

“…This layer is composed of TiO 2 nanoparticles and is intended to aid electron transfer (Figure 2). [29,36] In addition, in the case of conventional planar structures, a thin layer of TiO 2 can be deposited on the ITO, acting as an electron blocking layer. [37] In 2020, Tao and collaborators [38] developed a mesoporous PVSK cell modifying HTL using an organic molecule functionalized with fluoride.…”

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.
