Cigs Solar Cell Working Principle

An ideal solar cell can be represented by a current source connected in parallel with a rectifying diode as shown in the equivalent circuit of fig.

Cigs solar cell working principle.

Working principle of solar cell. Thin film solar cells 15m. Thin film solar cells are finally becoming competitive. Cigs cells have up to 10 efficiency with similar durability as silicon solar cells.

It is manufactured by depositing a thin layer of copper indium gallium and selenium on glass or plastic backing along with electrodes on the front and back to collect current. 2 the corresponding i v characteristic is described by the shockley solar cell equation 1 i i p h i o e q v k b t 1 where k b is the boltzmann constant t is the absolute temperature q 0 is the electron charge and v is the. Solar cell theory materials fabrication design modules and systems are discussed. Since they are a thin film technology they can be less costly than si cells.

When light reaches the p n junction the light photons can easily enter in the junction through very thin p type layer the light energy in the form of photons supplies sufficient energy to the junction to create a number of electron hole pairs. Working principle of cigs solar cells 6m. Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect. Solar cell is also termed as photo galvanic cell.

Cigs solar cell in full copper indium gallium selenide solar cell thin film photovoltaic device that uses semiconductor layers of copper indium gallium selenide cigs to absorb sunlight and convert it into electricity although cigs solar cells are considered to be in the early stages of large scale commercialization they can be produced by using a process that has the potential to reduce. The efficiency of cdte solar cells has reached just more than 15 percent and cigs solar cells have reached 20 percent efficiency. Particular attention is given to p n junction diodes including efficiency limits losses and measurements. Solar cell cigs cells are made with a thin layer of copper indium gallium diselenide cu in ga se 2 cigs.

Production of cigs solar cells 6m. The energy obtained from the sun directly into the electrical energy. Solar cell is a device or a structure that converts the solar energy i e. There are health concerns with the use of cadmium in thin film solar cells.

Because the material has a high absorption coefficient. The solar source of light energy is described and quantified along with a review of semiconductor properties and the generation recombination and the basic equations of photovoltaic device physics. In reality silicon wafer cells achieve on average 15 to 25 percent efficiency. This wavesol panel from ascent solar has.
