Next‐generation organic solar cells such as dye‐sensitized solar cells (DSSCs) and perovskite solar cells (PSCs) are studied at the National Institute of Advanced Industrial Science and Technology (AIST), and their materials, electronic properties, and fabrication processes are investigated. To enhance the performance of DSSCs, the basic structure of an electron donor, π‐electron linker, and electron acceptor, i.e., D–π–A, is suggested. In addition, special organic dyes containing coumarin, carbazole, and triphenylamine electron donor groups are synthesized to find an effective dye structure that avoids charge recombination at electrode surfaces. Meanwhile, PSCs are manufactured using both a coating method and a laser deposition technique. The results of interfacial studies demonstrate that the level of the conduction band edge (CBE) of a compact TiO2 layer is shifted after TiCl4 treatment, which strongly affects the solar cell performance. Furthermore, a special laser deposition system is developed for the fabrication of the perovskite layers of PSCs, which facilitates the control over the deposition rate of methyl ammonium iodide used as their precursor.

“…Michael Graetzel's group in 2016 reported an improved PCE of 19% with Li doped TiO 2 [71]. Jun et al [72] and Xiangling et al [73] also analysed the effect of Indium and Fe 3+ doping in TiO 2 , respectively, and found that the device performance was upgraded as compared to that of pristine TiO 2 . Doping in TiO 2 will lead to passivation in the oxygen deficiency and/or the low-level trap states generated at the time of material synthesis due to unsaturated Ti(III), and hence boost the performance.…”

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.

“…Thus, mesoporous TiO 2 ‐based PSCs yield a better photovoltaic performance compared with planar TiO 2 based PSCs. TiO 2 films also need be annealed at a high temperature to confirm the proper crystalline, resulting in higher cost and limitation of further applications . ZnO is also a material used as ETL widely.…”

Organic‐inorganic hybrid perovskite solar cells (PSCs) have developed rapidly in recent years owing to the low cost and high power conversion efficiency achieved. The excellent performance of PSCs is attributed to the superior electrical properties of each layer, including the electron transport layer (ETL), light‐harvest layer, hole transport layer. As one of the most promising ETL materials for PSCs, SnO2 shows excellent transmission, an appropriate energy band gap, a deep conduction band level, and high electron mobility, leading to efficient electron extraction and transport. Here, recent advancements in the PSCs with SnO2 ETLs and endeavors aimed at improving the performance of this photovoltaic device are reviewed. Several typical configurations of SnO2 based PSCs are discussed, including the planar structure, mesoporous structure, inverted structure and flexible PSCs. The efforts of modification and composite SnO2 with other metal oxides are also assessed. Finally, an overview of the perspectives and challenges for the future of SnO2 based PSCs is provided.
