چکیده
از آنجایی که سلول‌های خورشیدی حساس شده با رنگ کارایی مناسبی در ناحیه طیف مریی دارند، یک راه امیدوارکننده برای تولید انرژی پایدار، به‌ویژه در محیط‌های داخلی و کاربردهای ساختمانی، ارائه می‌کنند. بررسی تاثیر رنگدانه و همچنین تغییرات فوتوآند بر عملکرد سلول برای پیشبرد این سلول‌ها بسیار مهم است. این تحقیق بر تجزیه و تحلیل حساسیت اثر پارامترهای مهم برای افزایش کارایی این نوع سلول‌ها با استفاده از یک مدل عددی جدید با در نظر گرفتن عواملی مانند شدت تابش و ترکیب طیفی، از منابع نور معمولی داخلی مانند دیودهای ساطع نور تمرکز دارد. این پارامترها شامل انواع رنگدانه، پارامتر تله‌اندازی، ضریب انتشار و ضخامت فوتوآند است. این مدل جریان‌های پایا و گذرا را تحت شرایط تابش داخلی بررسی میکند و روابط وابسته به زمان/مکان را برای افزایش دقت ترکیب می‌کند و برهمکنش‌های الکترون، یدید و تری‌یدید را تحت شرایط محیطی مختلف بررسی می‌کند. نتایج نشان داد که رنگدانه N749 و ضخامت 20میکرومتر فتوآند بهترین تاثیر را بر عملکرد سلول دارد. در نهایت بر اساس تحلیل حساسیت انجام شده یک سلول با پارامترهای بهینه که بهترین علکرد را دارد معرفی شده‌است.

چکیده English

Since dye-sensitized solar cells (DSSCs) have good efficiency in the visible region, they offer a promising way to generate sustainable energy, especially in indoor environments and building applications. Investigating the effect of dye specifications and photoanode thickness changes on cell performance is very important for improving DSSCs. This research focuses on the sensitivity analysis of the impact of important parameters to increase DSSC efficiency using a new numerical model considering factors such as radiation intensity and spectral composition, from conventional indoor light sources such as LED and fluorescent lights. These parameters include dye types, trapping parameters, diffusion coefficients, and photoanode thickness. This model examines steady and transient currents under internal radiation conditions, incorporates time/space-dependent relationships to increase accuracy, and examines electron, iodide, and triiodide interactions under different environmental conditions. The results showed that N749 and 20µm thickness of photoanode have the best effect on cell performance. This study presents a sensitivity analysis to find optimal parameters to improve DSSC performance in real indoor conditions opening avenues for further research in optimizing DSSC technology for indoor energy harvesting applications, thereby advancing the field of renewable energy and sustainable technology integration.
