چکیده

در این مقاله، ابتدا مدل سلول خورشیدی تک‌پیوندی In0.5Ga0.5P < /span> در محیط اطلس نرم‌افزار سیلواکو (Silvaco)  پیاده‌سازی شده، سپس با تمرکز بر پارامترهای ساختاری سلول شامل ضخامت و آلایش لایه‌های پنجره، نشردهنده و جاذب، اثر تغییر این پارامترها بر عملکرد سلول شبیه‌سازی شده است. باتوجه‌به نتایج شبیه‌سازی، لایۀ جاذب بیشترین تأثیر را بر راندمان سلول داشته و لایه‌های نشردهنده و پنجره به‌ترتیب در جایگاه دوم و سوم قرار دارند. در ادامه، ضمن تحلیل نتایج حاصل از شبیه‌سازی به‌منظور بررسی اثرات متقابل پارامترهای موردبحث و یافتن بهترین مقدار برای آن‌ها، بهینه‌سازی انجام شد. باتوجه ‌به نتایج حاصل از بهینه‌سازی، مقدار بهینه برای ضخامت لایه‌های پنجره، نشردهنده و جاذب به‌ترتیب برابر um 08/0، um 07/0 و um 1/1 و نیز مقدار بهینۀ آلایش لایه‌ها به‌ترتیب برابر  1019×1،  1018×7/7 و  1017×7 به‌دست آمد. در‌نهایت، با شبیه‌سازی سلول به‌ازای مقادیر بهینۀ به‌دست‌آمده از بهینه‌سازی، راندمان سلول به رکورد 24/19% افزایش یافت.
