Amorton Amorphous Silicon Solar Cells

Amorton is the world's first integrated (series-connectable) amorphous silicon solar cell, developed by Panasonic. Unlike crystalline silicon, amorphous silicon features irregular atomic arrangements, leading to more frequent photon-silicon interactions and higher light absorption. This allows for the creation of ultrathin films for power generation. Amorton cells can be customized for various voltages by connecting multiple cells in series on a single substrate, offering flexibility in design for diverse applications. They are sensitive to visible light wavelengths, making them suitable for both power generation and light sensing.

Principles of Power Generation

Power is generated due to the photovoltaic effect of semiconductors. When a semiconductor is exposed to light, electrons and holes are generated. At a p/n junction, an internal electric field separates these charges, and when an external load is connected, electricity flows.

Light Source Categories

Amorton can be used under various light sources, including sunlight (standardized by Air Mass like AM-0, AM-1, AM-1.5) and artificial light (incandescent, fluorescent, LED, etc.).

Illumination Levels

Amorton performs well under varying illumination levels, from indoor office lighting (300-600 lx) to bright sunny outdoor conditions (100,000 lx).
