1）About Amorphous Solar Cell

Amorphous silicon (a-Si): It is the non-crystalline form of silicon which is a thin-film solar cells based on amorphous silicon compounds. The cell structure has a single sequence of p-i-n layers. When exposed to sun, their power output is significantly decreased. A-Si type thin film solar cells are commonly found in calculators. A-Si type thin film is manufactured in 6 steps. First the glass substrate is coated with a TCO (transparent conductive oxide) layer as front contact, followed by P1 laser scribing. Then a layer of a-Si is deposited followed by P2 laser scribing. Then a metal conductive layer is placed as back contact with the relative P3 laser scribing.

2）Amorphous Solar Panel’S Features

1)Copes easily with deviceʼs required drive voltage

Since multiple cells can be simultaneously connected in a series when the solar cells are formed, unlike the fabrication technique used with crystalline silicon solar cells in which multiple solar cells are severed and connected, it is easy to create cells with a variety of voltages.

2)Variety of shapes and forms

The methods used in amorphous silicon films have special features that allow other substrates, such as stainless steel or plastic films, to be used instead of customary glass substrates.

This means that previously unknown solar cells can also be created, including solar cells that are round, square, or any other complex shape or solar cells that can even be bent. It is also possible to create areas in these solar cells that just consist of transparent glass by etching.

3)High sensitivity within visible light spectrum

The human eye is sensitive to light from a range of about 400 to 700 nm wavelengths.

Since amorphous silicon solar cells are sensitive to light with essentially the same wavelengths, they can also be used as visible light sensors.

3）Principles of Power Generation

Power is generated in solar cells due to the photovoltaic effect of semiconductors.

1)When a semiconductor is exposed to a light source of suitable intensity, a large number of electrons (－) and holes (＋) are generated and form electricity.

2)At a p/n junction between two different semiconductor materials, the electrons are collected in the n-type material and the holes are collected in the p-type material by internal electric field.

3)When an external load is connected, electricity flows through the load. Then generated electricity can be used.
