1. Solar cell area: refers to the area (including grid lines) of all solar illumination surfaces of solar cells.
2. Monolithic solar cells: The smallest solar cells with positive and negative poles that convert solar radiation into electrical energy.
3. The effective light area of ​​a single solar cell refers to the difference between the geometrical area of ​​the single cell solar cell and the area occupied by the electrode.
4. Conversion efficiency: refers to the percentage of the maximum power of the solar cell subjected to light and the total radiation power incident on the solar cell.
5. Component (solar cell module): refers to the smallest detachable solar cell combination device with a package and internal connection that can independently provide direct current output.
6. Solar cell module area: refers to the total light surface area of ​​the solar cell module (including the edges, frames, and any projections).
7. Boards (solar panels): Assemblies that are assembled from a number of solar modules in a certain manner under one board are called boards (a board, often a unit of a square array).
8. Square array (solar cell square array): A DC power generation unit made up of a number of solar cell modules or solar panels assembled mechanically and electrically in a certain manner and having a fixed supporting structure. Does not include other.
9. The volt-ampere characteristic curve of a solar battery refers to the curve of the relationship between the current I flowing into the load and the battery terminal voltage V under a certain irradiance and temperature and different external circuit loads.
10. Short circuit current Isc: The output current of the photovoltaic generator when the terminal voltage is zero under a certain temperature and irradiation conditions.
11. Open circuit voltage Voc: The terminal voltage of the photovoltaic generator under no load (open circuit) under certain temperature and irradiation conditions.
12, standard test conditions: irradiance 1000W/m2, spectrum AM1.5, temperature 25 °C.
