PEROVSKITE-BASED NANOMATERIALS FOR HIGH-EFFICIENCY SOLAR CELLS UNDER PAKISTAN’S CLIMATIC CONDITIONS

Abstract

The increasing demand for sustainable and high-efficiency renewable energy technologies has intensified global interest in perovskite-based solar cells due to their exceptional photovoltaic properties, low fabrication cost, and tunable optoelectronic characteristics. However, the operational stability of perovskite solar cells remains a major challenge under harsh environmental conditions characterized by high temperature, humidity, and dust exposure, particularly in developing countries such as Pakistan. This study investigated the effectiveness of perovskite-based nanomaterials in enhancing the efficiency, thermal stability, and environmental durability of solar cells under Pakistan’s climatic conditions. A quantitative experimental research design was employed using laboratory-fabricated photovoltaic samples consisting of conventional perovskite solar cells, mixed-cation moisture-resistant perovskite cells, and encapsulated nanostructured perovskite devices. Data were collected through photovoltaic characterization, thermal stress testing, humidity exposure analysis, and environmental simulation techniques. Statistical analyses, including descriptive statistics, correlation analysis, regression analysis, and one-way ANOVA, were conducted to evaluate the relationship between nanomaterial properties and photovoltaic performance.

The findings revealed that advanced nanostructural engineering, surface passivation, and encapsulation significantly improved power conversion efficiency and reduced environmental degradation under high-temperature and high-humidity conditions. Mixed-cation and encapsulated perovskite solar cells demonstrated superior thermal stability, moisture resistance, and operational durability compared to conventional photovoltaic structures. The study concluded that perovskite-based nanomaterials possess substantial potential for developing cost-effective, high-efficiency, and climate-resilient solar technologies suitable for Pakistan’s environmental conditions. The research contributes to the advancement of renewable energy materials and provides practical insights for sustainable photovoltaic development in emerging economies
