چکیده

در این تحقیق پلیمرهای زیستی کیتوسان و کربوکسی متیلسلولز به عنوان عامل ژل کننده الکترولیت در ساخت سلول خورشیدی حساس شده با رنگ مورد استفاده قرار گرفتند. به منظور بررسی اثر این دو پلیمر بر عملکرد سلول‌های خورشیدی حساس شده با رنگ، مقادیر یکسانی از این دو پلیمر به طور مجزا به الکترولیت‌های مایع که هر دو شامل غلظت یکسانی از زوج اکسایش – کاهش I-/I3- بودند، اضافه گردید. مطالعهی طیفسنجی امپدانس الکتروشیمیایی و نتایج اندازهگیریهای فتوولتائی سلولها نشان داد که بازده دریافتی از سلول خورشیدی حاوی کربوکسی متیل سلولز بیشتر از سلول حاوی کیتوسان بود.
