This p-i-n junction corresponds to the p/n junction of a crystal silicon solar cell. In the process of this junction formation, a number of cells are connected in series on a substrate at one time. This allows any Three amorphous silicon layers positive hole are generated as a result of the reciprocal action Amorton is an integrated amorphous silicon solar cell which has been developed by SANYO. utilizing metal or plastics for the substrate, flexible solar cells can be produced. thin amorphous silicon film of less than 1 amorphous silicon than in crystal silicon, allowing much more light to be absorbed. Thus, an ultra- As a result, the reciprocal action between photons and silicon atoms occurs more frequently in irregular atomic arrangements as shown in the figures below. Unlike crystal silicon, in which atomic arrangements are regular, amorphous silicon features is defined as non-crystal material. and compound semiconductor solar cells. "Amorphous" refers to objects having no definite shape and Solar cells are classified according to the material employed, i.e., crystal silicon, amorphous silicon, electricity and supplies power to external loads. load. In this way, an a-Si solar cell converts light energy into When an external load is connected, electricity flows through the electrodes. electrodes respectively, resulting in a voltage difference between the are scattered in the p-type material. They are then collected at both electrons are diffused in the n-type material and the positive holes At a p/n junction between two different semiconductor materials, the between photons and silicon atoms. Amorton uses silane (SiH of suitable intensity, a large number of pairs of an electron and a semiconductors. When a semiconductor is exposed to a light source Solar cell power is generated using the photovoltaic effect of The Concept Behind Solar Cell Power Generation Amorphous Silicon Solar Cells that surpass those of the earlier crystalline silicon solar cells. amorphous silicon solar cells that feature a new device structure. SANYO was one of the first companies to focus on amorphous silicon solar cells, and and they have already been used in a wide range of applications. and can take advantage of the flexibility of thin film materials, This technology also allows larger area cells to be manufactured and thus are truly environmentally friendly devices. In addition, they require little energy to manufacture and use less raw materials, developed and is now mass producing the Amorton integrated type Of these technologies, amorphous silicon solar cells have many strengths and it can be used to produce electricity wherever and whenever sunlight is available. Solar energy is both a clean and inexhaustible resource, solar cells have the potential to replace fossil fuels as our main means of power generation. As a new energy tool which can effectively harness the amazing power of sunlight, The development of the solar cell is progressing with rapid speed. 1

Battery chargers Electronic calculators High sensitivity in the visible light region Solar cells with a variety of shapes can be created Solar cells with a variety of voltages can be created The methods used to form amorphous films have special features that allow other substrates, such as Since amorphous silicon solar cells are sensitive to light with essentially the same wavelengths, in addition to solar cells, they can also be used as visible light sensors. connected, multiple cells can be connected in series at the same time as the cells are formed, it is easy to stainless steel or plastic films, to be used in place of the usual glass substrate. This means that previously It is also possible to create areas in these solar cells that consist of just transparent glass by etching. unknown solar cells, solar cells that are round, square, or any complex shape, or solar cells that can be create batteries with a variety of voltages.

Radiant spectrum of light source and spectral sensitivity of solar cells When sunlight and fluorescent light are compared in terms of brightness, the results are shown as follows: 2. Brightness The following outline describes the various categories: The general light source for solar cells is sunlight out of doors, and fluorescent or incandescent light indoors. 1. Categories of light sources This is because photoelectric conversion efficiency changes with respect to the wavelength and intensity of the light. The output of solar cells differ depending on the categories of light sources to which they are exposed. Solar Cell Output and Light Sources 11
