Abstract

The demand for renewable energy sources has accelerated research into high-efficiency solar cells. Optical materials play a critical role in enhancing light absorption and overall energy conversion efficiency. Understanding the properties and performance of various optical materials is essential for optimizing solar cell technology. This study aims to compare different optical materials used in solar cells to evaluate their effectiveness in maximizing solar energy conversion. The focus is on identifying materials that offer superior optical characteristics and compatibility with existing solar cell technologies. A comparative analysis was conducted on several optical materials, including silicon dioxide (SiO2), titanium dioxide (TiO2), and organic polymers. The study involved synthesizing these materials and assessing their optical properties using UV-Vis spectroscopy and photoluminescence measurements. Efficiency tests were performed on solar cell prototypes incorporating these materials. The findings reveal that titanium dioxide exhibited the highest light absorption and photonic efficiency compared to silicon dioxide and organic polymers. Solar cells utilizing TiO2 demonstrated a significant increase in overall efficiency, achieving conversion rates of up to 22%. In contrast, organic polymers showed lower performance but offered advantages in flexibility and lightweight applications. This research highlights the importance of selecting appropriate optical materials to enhance solar cell efficiency. Titanium dioxide emerges as a leading candidate for high-performance solar cells, while organic polymers may provide alternative solutions for specific applications. Continued exploration of optical materials will be crucial for advancing solar technology and meeting global energy demands.

Abstract

Food security debates have increasingly shifted from the question of how much food is produced to the question of what nutritional value that food delivers to populations. This study aimed to examine how the nutritional quality of agricultural products, particularly functional foods and nutrient-rich crops, contributes to stronger household food security. A convergent mixed-methods design was employed, combining laboratory analysis of 30 agricultural product samples, household survey data from 150 respondents, and in-depth interviews with 15 key informants drawn from farming, market, and nutrition sectors. The findings showed that nutrient-rich crops and functional food products contained substantially higher levels of protein, iron, zinc, dietary fiber, beta-carotene, and phenolic compounds than conventional staples. Households with greater access to these products reported higher dietary diversity, lower food insecurity scores, and better perceived dietary adequacy. Qualitative evidence further revealed that local processing, market accessibility, nutrition awareness, and community acceptance strengthened the food security effects of nutritionally superior products. Nutritional quality in agricultural products can therefore be understood as a strategic pillar of food security, supporting a shift from quantity-oriented agriculture toward nutrition-sensitive, health-promoting, and more resilient food systems. These findings highlight the need for integrated agricultural, nutritional, and policy interventions across food systems.
