چکیده

به منظور افزایش بهره سلول های خورشیدی لایه نازک، روش هایی برای طراحی مناسب نانوساختارهای پلاسمونیکی و دی الکتریک در سلول پیشنهاد و بررسی می کنیم که امکان برانگیختگی تعداد قابل توجهی از مدهای مختلف اپتیکی و در نتیجه افزایش احتمال جذب فوتون توسط سلول را فراهم می کنند. با بهره گیری از تکنیک محاسباتی تفاضل متناهی در حوزه زمان (FDTD)، برهمکنش نور با ساختارهای پیشنهادی را مدلسازی و چگونگی تنظیم مدهای اپتیکی با تغییر پارامترهای سلول را مورد بررسی قرار می دهیم. نشان می دهیم که با قرار دادن توری شبه تناوبی یک بعدی از نانومیله های پلاسمونیکی و دی الکتریک، به ترتیب، در انتها و بر روی سلول، می توان تمام مدهای اپتیکی مورد نظر را به صورت کنترل شده برانگیخته کرد.

چکیده [English]

To enhance light absorption in thin film solar cells, we propose and investigate several approaches to design dielectric and plasmonic nanostructures for efficient excitement of numerous optical modes in the solar cells, leading to an increase in the number of absorbed photons within absorbing layer. Two-dimensional Finite Difference Time Domain (2D-FDTD) method is employed to model light interaction with the proposed structures and to investigate the effect of solar cell parameters on the optical modes excitation. It is shown that several optical modes can be excited and adjusted by placing one dimensional dielectric and plasmonic quasi-periodic nanogratings on top and at the bottom of the active layer, respectively.
