High-performance photovoltaic cells use semiconductors to convert sunlight into clean
electrical power, and transparent dielectrics or conductive oxides as antireflection coatings …

Thin film solar cells are one of the important candidates utilized to reduce the cost of
photovoltaic production by minimizing the usage of active materials. However, low light …

Enhancing the light absorption in ultrathin-film silicon solar cells is important for improving
efficiency and reducing cost. We introduce a double-sided grating design, where the front …

High-speed, high-efficiency photodetectors play an important role in optical communication
links that are increasingly being used in data centres to handle higher volumes of data traffic …

We use a rigorous electromagnetic approach to analyze the fundamental limit of light-
trapping enhancement in grating structures. This limit can exceed the bulk limit of 4n^ 2, but …

Dielectric and metallic gratings have been studied for more than a century. Nevertheless,
novel optical phenomena and fabrication techniques have emerged recently and have …

The wings of the black butterfly, Pachliopta aristolochiae, are covered by micro-and
nanostructured scales that harvest sunlight over a wide spectral and angular range …

Crystalline silicon is an attractive photovoltaic material because of its natural abundance,
accumulated materials and process knowledge, and its appropriate band gap. To reduce …

We develop a semianalytical model to describe bound states in the continuum (BICs) in
photonic crystal slabs. We model leaky modes supported by photonic crystal slabs as a …

We theoretically investigate the light-trapping properties of one-and two-dimensional
periodic patterns etched on the front surface of c-Si and a-Si thin film solar cells with a silver …
