Solar cell

A solar cell , or photovoltaic cell , is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect , which is a physical and chemical phenomenon. Individual solar cell devices are often the electrical building blocks of photovoltaic modules , known colloquially as solar panels. The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0. Solar cells are described as being photovoltaic , irrespective of whether the source is sunlight or an artificial light. In addition to producing energy, they can be used as a photodetector for example infrared detectors , detecting light or other electromagnetic radiation near the visible range, or measuring light intensity. In contrast, a solar thermal collector supplies heat by absorbing sunlight , for the purpose of either direct heating or indirect electrical power generation from heat. A "photoelectrolytic cell" photoelectrochemical cell , on the other hand, refers either to a type of photovoltaic cell like that developed by Edmond Becquerel and modern dye-sensitized solar cells , or to a device that splits water directly into hydrogen and oxygen using only solar illumination.

Metrics details. Light manipulation has drawn great attention in photodetectors towards the specific applications with broadband or spectra-selective enhancement in photo-responsivity or conversion efficiency. In this work, a broadband light regulation was realized in photodetectors with the improved spectra-selective photo-responsivity by the optimally fabricated dielectric microcavity arrays MCAs on the top of devices. Both experimental and theoretical results reveal that the light absorption enhancement in the cavities is responsible for the improved sensitivity in the detectors, which originated from the light confinement of the whispering-gallery-mode WGM resonances and the subsequent photon coupling into active layer through the leaky modes of resonances. In addition, the absorption enhancements in specific wavelength regions were controllably accomplished by manipulating the resonance properties through varying the effective optical length of the cavities.

Plasmonics can be used to improve absorption in optoelectronic devices and has been intensively studied for solar cells and photodetectors. Graphene has recently emerged as a powerful plasmonic material. It shows significantly less loss compared to traditional plasmonic materials such as gold and silver and its plasmons can be tuned by changing the Fermi energy with chemical or electrical doping.

Nanophotonics silicon solar cells: status and future challenges

В голове у него не было ни единой мысли - полная пустота. Он не знал ни где он находится, ни кто его преследует и мчался, подгоняемый инстинктом самосохранения. Он не чувствовал никакой боли - один лишь страх. Пуля ударила в кафельную плитку азульехо чуть сзади. Осколки посыпались вниз и попали ему в шею.

 Вот хочу попробовать сделать кое-какую перенастройку да проверить электронную почту, - сказал Хейл. Он смотрел на нее с нескрываемым любопытством.  - Что ты сказала. Чем ты занята.

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.
