The Working Principle of a Solar Cell

The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag- netic radiation. The photovoltaic effect is closely related to the photoelectric effect, where electrons are emitted from a material that has absorbed light with a frequency above a material-dependent

How do Organic Solar Cells Work? As with other solar cell technologies, the purpose of an organic solar cell is to generate electricity from sunlight. This is achieved when the energy of light is equal to or greater than the band gap, leading to absorption and excitation of an electron from the HOMO to the LUMO.

6 FAQs about [Working mechanism of organic solar cells]

What is the operating mechanism of organic solar cells?

The operating mechanism of organic solar cells are one of the most researched and debated fields. In general all the main differences in mechanism in case of organic solar cell arises due to the generation of electrostatically bound electron-hole pair in organic solar cells instead of free charges. Further, this concept is explained in detail.

How do organic solar cells work?

Organic solar cells Organic solar cell is a type of device made up of thin films of carbon-based polymer or molecule as a donor blended with an acceptor material. The donor absorbs sunlight, transfers electrons to acceptor, and transports holes to anode, while the acceptor takes electrons from donor and transports electrons to cathode.

Are organic solar cells effective?

Organic solar cells (OSC) based on organic semiconductor materials that convert solar energy into electric energy have been constantly developing at present, and also an effective way to solve the energy crisis and reduce carbon emissions. In the past several decades, efforts have been made to improve the power conversion efficiency (PCE) of OSCs.

What determines the CC of organic solar cells?

The η cc depends on device architecture, the energy levels of the active layer and the electrodes, and surface recombination at the organic-metal interface [ 4, 17 ]. In summary, organic solar cell device structures, materials, basic concepts, and device physics are introduced.

Why do organic solar cells have a low carrier mobility?

In a typical organic solar cell made by the donor–acceptor blends, the overlap of wavefunctions between adjacent sites in both the donor and acceptor phase is not strong; the carrier transport states are also localized. Thus, the separated charges can only transport by hopping from one localized site to the next with a low carrier mobility.

What is the difference between organic solar cells and photovoltaic cells?

They are efficient and durable, but can be expensive to produce. Organic solar cells, on the other hand, are made by depositing a thin layer of photovoltaic material onto a substrate, such as glass or polymeric material. They can also be made into a variety of shapes and sizes, making them more versatile.
