Abstract

Photovoltaic cells or PV cells can be produced from multiple points of view and from a wide range of materials. Notwithstanding this distinction, they all play out a same task of harvesting solar energy and changing it over to useful electricity. The most well-known material for sun for solar panel development is silicon which has semiconducting properties. A few of these solar cells are needed to build a solar panels board and many panels make up a photovoltaic array.

Keywords: Thin Film Cells, Monocrystalline Silicon Cell, Photovoltaic cells

Introduction

There are three types of PV cell advancements that overwhelm the world market: monocrystalline silicon, polycrystalline silicon, and thin film. Higher efficiency PV advancements, including gallium arsenide and multi-intersection cells, are more uncommon because of their significant expense, yet are great for use in concentrated photovoltaic frameworks and space applications. There is additionally a variety of arising PV cell innovations which incorporate Perovskite cells, natural sun powered cells, color sharpened sun oriented cells and quantum spots.

Monocrystalline Silicon Cell

The first commercially available solar cells were produced using monocrystalline silicon, which is a very unadulterated type of silicon. To produce these, a seed crystal is pulled out of a mass of liquid silicon making a tube shaped ingot with a single, continuous, crystal lattice structure. This crystal is then mechanically sawn into slight wafers, cleaned and doped to make the necessary p-n junction. After an antireflective coating and the front and rear metal contacts are added, the cell is finally wired and bundled close by numerous different cells into a full sun powered panel. Monocrystalline silicon cells are profoundly effective, however their manufacturing process is slow and labour intensive , making them more costly than their polycrystalline or thin film counter parts.

Thin Film Cells

Although crystalline PV cells rule the market, cells can likewise be produced using thin film making them significantly more flexible and durable. One kind of thin film PV cell is amorphous silicon (a-Si) which is created by depositing several layers of silicon on to a glass substrate. The outcome is an extremely thin and flexible cell which utilizes under 1% of the silicon required for a glasslike cell. Because of this decrease in raw material and a less energy intensive manufacturing process, amorphous silicon cells are a lot less expensive to create. Their effectiveness, notwithstanding, is incredibly decreased on the grounds that the silicon molecules are considerably less arranged than in their crystalline forms leaving 'dangliing bonds' that join with different components making them electrically inactive.

Different types of thin film cells incorporate copper indium gallium diselenide (CIGS) and cadmium telluride (CdTe). These cell innovations offer higher efficiencies than amphorous silicon, however contain uncommon and poisonous components including cadmium which requires additional precautionary measures during fabricate and inevitable reusing.

High Efficiency Cells

Other cell advancements have been created which work at a lot higher efficiencies than those referenced above, yet their higher material and assembling costs presently restrict wide spread business use.

Gallium Arsenide

Silicon isn't the solitary material reasonable for crystalline PV cells. Gallium arsenide (GaAs) is an elective semiconductor which is exceptionally reasonable for PV applications. Gallium arsenide has a comparable structure to that of monocrystalline silicon, however with substituting gallium and arsenic molecules.

Because of its higher light absorption coefficient and more band gap, Gas cells are substantially more proficient than those made of silicon. Also, Gas cells can work at a lot higher temperatures without significant execution corruption, making them appropriate for concentrated photovoltaic. Gas cells are created by depositing layers of gallium and arsenic onto a base of single crystal Gas, which characterizes the direction of the new crystal development. This cycle makes Gas cells considerably more costly than silicon cells, making them valuable just when high efficiency is required, for example, space applications.
