- Solar Technology

- 太陽光発電 is a power generation technology that converts solar light energy to produce electricity. (太陽光発電 using solar cells that generate electricity by photoelectric effect when it receives sunlight).
- The photovoltaic power generation system consists of a module composed of solar cells and a storage battery and power conversion device.

- Principle of power generation by solar cell

- A photovoltaic cell is designed to convert solar energy into electrical energy. It uses a photovoltaic effect that occurs when a light is irradiated on a 顧客支援 surface of a metal and a semiconductor or a pn junction of a semiconductor.
- Selenium photovoltaic cells, and sulfurous copper are based on the 顧客支援 between metal and semiconductor, and the silicon photocell that is being used as a solar cell uses a semiconductor PN junction.

- Principle of power generation by PN junction

- Solar cells are semiconductors represented by silicon. They are naturally developed by the development of semiconductor technology and semiconductor characteristics.
- Solar cells have a structure in which N (negative) type semiconductors having different electrical properties are bonded to P (positive) type semiconductors, and two semiconductor boundary portions are referred to as PN junctions.
- When the sunlight reaches the solar cell, the sunlight is absorbed by the sun cells, and the energy of the absorbed sunlight causes the particles (+) and electrons (+) And electrons (-) move toward the N-type semiconductor, so that the potential is generated.
For this reason, when a load such as a motor or a motor is connected to a front electrode and a back electrode, electric current flows. This is the principle of the photovoltaic generation by the pn junction of the solar cell.
