EFFECTS OF BENDING AND STRETCHING ON HYBRID ORGANIC-INORGANIC TRIHALIDE PEROVSKITE SOLAR CELLS
Abstract:
Hybrid organic-inorganic trihalide perovskite solar cells have emerged as a promising technology for efficient and cost-effective solar energy conversion. However, their mechanical flexibility and durability are critical factors for their successful integration into various applications. This abstract explores the effects of bending and stretching on the performance and stability of hybrid organic-inorganic trihalide perovskite solar cells.
Bending and stretching can induce mechanical strain and stress on the perovskite layer, affecting the device’s electrical and optoelectronic properties. Investigations have been carried out to understand the impact of mechanical deformation on the power conversion efficiency (PCE), stability, and long-term performance of these solar cells.
Recent studies have demonstrated that moderate bending, within a certain range, can enhance the performance of perovskite solar cells by reducing charge recombination and improving charge transport properties. However, excessive bending or stretching can lead to cracks, defects, and degradation of the perovskite layer, resulting in reduced device performance and stability.
Strategies to enhance the mechanical flexibility of perovskite solar cells include modifying the device architecture, engineering the composition and morphology of the perovskite layer, and employing flexible substrates and encapsulation materials. These approaches aim to mitigate the detrimental effects of mechanical deformation and improve the overall mechanical stability of the solar cells.
Understanding the effects of bending and stretching on hybrid organic-inorganic trihalide perovskite solar cells is crucial for the development of flexible and reliable solar energy harvesting devices. Further research is required to optimize the device design, materials selection, and manufacturing processes to achieve high-performance, mechanically robust perovskite solar cells suitable for practical applications.
Keywords: hybrid perovskite solar cells, bending, stretching, mechanical deformation, flexibility, stability, power conversion efficiency, device architecture.
