Perovskite Solar Cells: Assessment of the Materials, Efficiency, and Stability

Abstract

Solar cells based on organic-inorganic lead halide perovskites are popular in the photovoltaic community due to their high efficiency, low cost, and solution processability. Understanding the fundamentals of metal halide perovskite and its interfaces is extremely important for achieving high-quality materials and developing efficient devices using these materials with the necessary properties. Various methodologies have been used to evaluate the excellent optoelectronic properties, efficiency, and stability of PSCs. In this article, we reviewed the case studies of characterization techniques to investigate structural, optical, and electrical properties of perovskite material via electron microscopic techniques (SEM and TEM), <em>J-V</em> measurements, AFM, XRD, and spectroscopy techniques (PL, UV-vis, XPS, Raman, FTIR, and EIS). PSCs also need to have long-term stability and large-scale applicability for successful commercialization. In this review, we studied perovskite in detail to understand the key properties of the materials to facilitate the commercialization of PSCs.

A Theoretical Study to Investigate the Impact of Bilayer Interfacial Modification in Perovskite Solar Cell

“…The working temperature of the device also significantly affects the performance and stability of the solar cell. [ 37 ] To investigate the influence of temperature, it was varied from 300 K (26.85 °C) to 340 K (66.85 °C) with a step of 10 K, as shown in Figure 6 .…”

Benzoic acid inhibits intrinsic ion migration for efficient and stable perovskite solar cells

“…[1][2][3] Nowadays, PSC has realized a power conversion efficiency (PCE) of 26.1%, comparable with those of the market silicon solar cells, which is mainly attributed to the low excitation energy, excellent light absorbency and long carrier lifetime of halide perovskite materials. [4][5][6][7][8][9] Although the PSC has made some progress in recent years, the defects of grain boundary, I vacancy (V I ) and Pb vacancy (V PB ) in hybrid perovskite lms are still striking. 1,3,10 The above defects and the grain boundaries can be named as trap states, trapping/recombining photogenerated carriers, [11][12][13][14] which severely affects the PSC efficiency and device stability.…”

Machine Learning in Perovskite Solar Cells: Recent Developments and Future Perspectives

“…Perovskite solar cells (PSCs) have a lot of potential, and the reported efficiencies drastically rose from 3.8% to 26.08% in the development period of almost one decade. [ 1–10 ] PSCs, with their exceptional photovoltaic properties and ease of fabrication, have emerged as a promising contender in the realm of next‐generation solar energy conversion devices.
