“…Perovskite Solar Cells the carbon-based HTL-free PSCs and claimed the possibility of promoting PSCs' commercialization. [11,12] Generally, highefficiency inorganic PSCs are always made by coating a CsPbI 2 Br or CsPbBr 3 halide layer on mesoscopic TiO 2 film, [13,14] a state-of-the-art electron-transporting layer (ETL) to collect electrons from photosensitizers in mesoscopic solar cells including dye-sensitized solar cells and PSCs. [15,16] However, the high sintering temperature of TiO 2 films up to 500 °C is necessary for increasing crystallinity and carrier transfer ability, resulting in higher energy consumption and tedious procedures.…”

Perovskite solar cells with cost-effectiveness, high power conversion efficiency, and improved stability are promising solutions to the energy crisis and environmental pollution. However, a wide-bandgap inorganic-semiconductor electron-transporting layer such as TiO can harvest ultraviolet light to photodegrade perovskite halides, and the high cost of a state-of-the-art hole-transporting layer is an economic burden for commercialization. Here, the building of a simplified cesium lead bromide (CsPbBr ) perovskite solar cell with fluorine-doped tin oxide (FTO)/CsPbBr /carbon architecture by a multistep solution-processed deposition technology is demonstrated, achieving an efficiency as high as 4.1% and improved stability upon interfacial modification by graphene quantum dots and CsPbBrI quantum dots. This work provides new opportunities of building next-generation solar cells with significantly simplified processes and reduced production costs.

“…[19][20][21][22][23][24] Soon, initially proposed high-efficient perovskite solar cells (PSCs) inherited the structure of solid-state dyesensitized solar cells and have been rapidly extended to several types of p-i-n, p-i, and i-n and even metal-semiconductormetal (MSM) junction solar cells. [25][26][27][28][29][30][31][32][33][34][35][36] For most high efficient PSCs, they commonly contain both ETL and hole-transporting layer (HTL) to efficiently collect one kind of charge while block the other kind to avoid carrier recombination thus high performance can be ensured. [37][38][39][40][41] The widely used material for the ETL is TiO 2 that needs a high temperature sintering process which consumes extra energy and limits the scalability of PSCs.…”

Perovskite solar cells (PSCs) have shown great potential for photovoltaic applications with their unprecedented power conversion efficiency advancement. Such devices generally have a complex structure design with high temperature processed TiO2 as the electron transport layer (ETL). Further careful design of device configuration to fully tap the potentials of perovskite materials is expected. Particularly, for the practical application of PSCs, it is crucial to simplify their device structures thus the associated manufacturing process and cost while maintaining their efficiency to be comparable with the conventional devices. But how simple is simple? ETL‐free PSCs promise the simplest structured, thus simple manufacturing processes and low cost large area PSCs in practical applications. They can also help the further exploration of the great potential of perovskite materials and understanding the working principle of PSCs. Within this review, the evolution of the PSC is outlined by discussing the recent advances in the simplification of device configuration and processes for cost effective, highly efficient, and robust PSCs, with a focus on ETL‐free PSCs. Their advancement, key issues, working mechanism, existing problems, and future performance enhancements. This review aims to promote the future development of low cost and robust ETL‐free PSCs toward more efficient power output.

“…According to calculations done by Maniarasu et al [204] in the fabrication of one metre square perovskite solar cell with 70% active area, 52% of the total raw material cost is taken up by the hole transporting material (Spiro-OMeTAD-604 USD) and counter electrode (gold-330 USD), and 43% by FTO glass (766 USD). On the other hand, Perovskite layer takes only 0.0038% of the total cost.…”

Abstract:For any given technology to be successful, its ability to compete with the other existing technologies is the key. Over the last five years, perovskite solar cells have entered the research spectrum with tremendous market prospects. These cells provide easy and low cost processability and are an efficient alternative to the existing solar cell technologies in the market. In this review article, we first go over the innovation and the scientific findings that have been going on in the field of perovskite solar cells (PSCs) and then present a short case study of perovskite solar cells based on their energy payback time. Our review aims to be comprehensive, considering the cost, the efficiency, and the stability of the PSCs. Later, we suggest areas for improvement in the field, and how the future might be shaped.
