Simulations of solar cell absorption enhancement using resonant modes of a nanosphere array
We propose an approach for enhancing the absorption of thin-film amorphous silicon solar cells using periodic arrangements of resonant dielectric nanospheres deposited as a continuous film on top of a thin planar cell. We numerically demonstrate this enhancement using 3D full field finite difference time domain simulations and 3D finite element device physics simulations of a nanosphere array a...

متن کاملLimit of absorption enhancement in solar cells with guided modes
Providing green energy for human consumption has become a main goal of industry and research in recent decades. Photovoltaic technology is a main candidate for this aim but it requires price reduction and efficiency increase to enable large scale commercialization. To comply with the cost effectiveness, the cells can be made very thin to reduce material consumption and materials with well-estab...
متن کاملMicrolens array induced light absorption enhancement in polymer solar cells.
Over the last decade, polymer solar cells (PSCs) have attracted a lot of attention and highest power conversion efficiencies (PCE) are now close to 10%. Here we employ an optical structure - the microlens array (MLA) - to increase light absorption inside the active layer, and PCE of PSCs increased even for optimized devices. Normal incident light rays are refracted at the MLA and travel longer ...
