Photovoltaic cells are semiconductor devices with photovoltaic conversion characteristics, which directly convert solar radiation into direct current. They are the most basic unit of photovoltaic power generation. The unique electrical characteristics of photovoltaic cells are the incorporation of certain elements (such as phosphorus or boron) into crystalline silicon, resulting in permanent imbalances in the molecular charge of the material, forming semiconductor materials with special electrical properties. Under sunlight, free charges can be generated in semiconductors with special electrical properties. These free charges move and accumulate in a directional manner, forming an electromotive force at both ends. When conductors are used to close both ends, a current is generated. This phenomenon is known as the "photovoltaic effect," or "photovoltaic effect.".

光伏发电的组成

Composition of photovoltaic power generation

分布式光伏发电系统由光伏方阵（光伏方阵由光伏组件串并联而成)、光伏逆变器、光伏支架、光伏并网箱、控制器（可选）、蓄电池组（可选）、交直流电缆等部分组成，发电售电给电网，获得相应收入。

The distributed photovoltaic power generation system is composed of a photovoltaic array (photovoltaic array is composed of photovoltaic modules in series and parallel), a photovoltaic inverter, a photovoltaic bracket, a photovoltaic grid box, a controller (optional), a battery pack (optional), and AC/DC cables. It generates electricity and sells it to the national power grid to obtain corresponding revenue.

太阳能资源取之不尽，用之不竭，而且太阳能在地球上分布广泛，只要有光照的地方就可以使用光伏发电系统，不受地域、海拔等因素的限制。

Solar energy resources are inexhaustible, and solar energy is widely distributed on the earth. As long as there is light, photovoltaic power generation systems can be used, regardless of geographical and altitude constraints.

光伏发电本身不使用燃料，不排放包括温室气体和其它废气在内的任何物质，不污染空气，不产生噪声，对环境友好，不会遭受能源危机或燃料市场不稳定而造成的冲击，是真正绿色环保的新型可再生能源。

Photovoltaic power generation itself does not use fuel, does not emit any substances including greenhouse gases and other exhaust gases, does not pollute the air, does not generate noise, is environmentally friendly, and does not suffer the impact of energy crises or instability in the fuel market. It is a truly green and environmentally friendly new type of renewable energy.

光伏发电无机械传动部件，操作、维护简单，运行稳定可靠。

Photovoltaic power generation has no mechanical transmission components, simple operation and maintenance, and stable and reliable operation.

光伏发电系统工作性能稳定可靠，使用寿命长，晶体硅太阳能电池寿命可长达20-35年。

Photovoltaic power generation systems have stable and reliable performance and long service life. The life of crystalline silicon solar cells can be as long as 20-35 years.
