Recent research has unveiled the potential of utilizing Tebalan shells from Tuban Beach as a sustainable material for perovskite solar cells (PSCs), presenting a promising alternative to traditional silicon-based solar technology. This innovative approach not only aligns with the global shift towards renewable energy but also highlights the value of natural resources in advancing energy efficiency.
The study, spearheaded by Roihatur Rohmah from Universitas Nahdlatul Ulama Sunan Giri, explores the synthesis of perovskite calcium titanate (CaTiO3) using calcium carbonate extracted from the shells. This method demonstrates a more accessible manufacturing process compared to conventional solar cell technologies, which often rely heavily on silicon. “Our research shows that natural materials can serve as effective components in solar energy systems, potentially reducing costs and environmental impact,” Rohmah stated.
The research methodology included various phases such as substrate preparation, synthesis of the perovskite material, and extensive testing, including X-ray diffraction (XRD) analysis to confirm the crystal structure of the synthesized calcium titanate. The results were promising, with XRD testing revealing that 68.2% of the calcined powder successfully formed the desired perovskite structure.
Rohmah’s team also evaluated the electrical properties of the solar cells under different light sources, finding that the cells exhibited higher performance under daylight conditions compared to warm white lamps. The efficiency peaked at an Air Mass of 1.5, achieving a value of 0.000127%. While this figure may seem modest, it represents a significant step toward enhancing the efficiency of PSCs made from environmentally friendly materials.
The implications of this research extend beyond academic interest. As the energy sector increasingly prioritizes sustainability, the ability to produce solar cells using locally sourced, natural materials could lead to reduced manufacturing costs and a lower carbon footprint. This shift not only supports environmental goals but also opens avenues for economic growth in regions rich in such natural resources.
Rohmah emphasized the broader significance of this work, stating, “By leveraging local materials, we can create a more sustainable energy future that supports both the economy and the environment.” This perspective is crucial as stakeholders in the energy sector seek innovative solutions to meet rising energy demands while adhering to sustainability targets.
The findings of this research have been published in the “Journal of Physics Education and Technology” (JPFT), underscoring the academic community’s commitment to advancing renewable energy technologies. As the world moves towards greener alternatives, studies like this one could catalyze further developments in the field, paving the way for more efficient and eco-friendly solar energy solutions.
