Omnidirectional Broadband Silicon-Based Solar Cells

The relatively high efficiency of solar cells based on silicon (Si) has led them to dominate the solar cell industry for the past few decades. It is of current interest to develop the photon management with nanostructures since the ability to suppress the reflection and light trapping over a broad range of wavelengths and incident angles plays an important role in the performance of optoelectronic devices, such as photodetectors, light-emitting diodes, optical components, or photovoltaic systems. A variety of photon management strategies are developed for more efficient Si photovoltaic devices and are discussed in this talk.
