原理剖析：讓陽光轉化為電能

Principle analysis: Convert sunlight into electrical energy

光伏發電基于半導體的光電效應原理。當太陽光照射到由 P 型和 N 型半導體組成的光伏電池上時，光子的能量被半導體吸收，使得半導體內部的電子獲得足夠能量，從而脫離原子的束縛，產生電子 - 空穴對。在 P 型和 N 型半導體的交界面處，由于存在內建電場，電子和空穴會分別向相反方向移動，從而在電池兩端形成電勢差。當外部電路接通時，就會有電流流過，實現了太陽能到電能的直接轉換。多個光伏電池通過串聯和并聯的方式，組成光伏組件，進而構建起大規模的光伏發電系統。

Photovoltaic power generation is based on the principle of semiconductor photoelectric effect. When sunlight shines on a photovoltaic cell composed of P-type and N-type semiconductors, the energy of photons is absorbed by the semiconductor, allowing the electrons inside the semiconductor to gain enough energy to break free from atomic constraints and produce electron hole pairs. At the junction of P-type and N-type semiconductors, due to the presence of an built-in electric field, electrons and holes will move in opposite directions, forming a potential difference at both ends of the battery. When the external circuit is connected, current flows through, achieving direct conversion of solar energy to electrical energy. Multiple photovoltaic cells are connected in series and parallel to form photovoltaic modules, thereby constructing a large-scale photovoltaic power generation system.

顯著優勢：多維度引領能源變革

Significant advantage: multidimensional leadership in energy transformation

1. 清潔環保

1. Clean and environmentally friendly

光伏發電在發電過程中不產生溫室氣體排放，也不會釋放有害污染物，從源頭上避免了對空氣、土壤和水源的污染。與傳統化石能源相比，每發一度電，光伏發電可減少約 0.8 千克的二氧化碳排放，有效助力全球應對氣候變化。

Photovoltaic power generation does not produce greenhouse gas emissions or release harmful pollutants during the power generation process, avoiding pollution of air, soil, and water sources from the source. Compared with traditional fossil fuels, photovoltaic power generation can reduce carbon dioxide emissions by about 0.8 kilograms per kilowatt hour, effectively helping the world to address climate change.

2. 可再生性

2. Reproducibility

太陽源源不斷地向地球輸送能量，太陽能是一種幾乎取之不盡、用之不竭的可再生能源。這意味著光伏發電不受化石能源儲量限制，為人類能源供應提供了長期穩定的保障。

The sun continuously delivers energy to the earth, and solar energy is an almost inexhaustible and renewable energy source. This means that photovoltaic power generation is not limited by fossil energy reserves, providing a long-term stable guarantee for human energy supply.

3. 分布式特性

3. Distributed characteristics

光伏發電系統安裝靈活，可根據需求分散建設。從家庭屋頂到工業廠房，從偏遠山區到城市商業區，都能因地制宜地搭建光伏發電設施，實現電力的就近生產和消納，降低輸電損耗，提高能源利用效率。

The installation of photovoltaic power generation systems is flexible and can be built in a decentralized manner according to demand. From residential rooftops to industrial plants, from remote mountainous areas to urban commercial areas, photovoltaic power generation facilities can be built according to local conditions to achieve nearby production and consumption of electricity, reduce transmission losses, and improve energy utilization efficiency.

多元應用：滲透各領域

Diversified applications: permeating various fields

1. 家庭光伏發電

1. Household photovoltaic power generation

越來越多家庭在屋頂安裝光伏發電系統，不僅滿足自身用電需求，多余的電量還能并網出售，為家庭帶來額外收入。這種模式既實現了能源自給自足，又響應了環保理念。

More and more households are installing photovoltaic power generation systems on their roofs, which not only meet their own electricity needs, but also allow excess electricity to be sold on the grid, bringing additional income to households. This model not only achieves energy self-sufficiency, but also responds to environmental protection concepts.

2. 工業

2. Industry

商業應用

Commercial Applications

許多工業企業和商業場所利用閑置屋頂建設大規模光伏發電站，降低企業用電成本，提升企業的社會形象。一些大型商場、酒店還將光伏發電與建筑一體化設計，打造綠色建筑典范。

Many industrial enterprises and commercial venues use idle roofs to construct large-scale photovoltaic power plants, reducing their electricity costs and enhancing their social image. Some large shopping malls and hotels also integrate photovoltaic power generation with building design, creating a model of green building.

3. 偏遠地區供電

3. Power supply in remote areas

在電網覆蓋不到的偏遠地區，光伏發電為居民生活、農業灌溉、通信基站等提供了可靠的電力保障，改善了當地居民的生活質量，推動了偏遠地區的經濟發展。

In remote areas where the power grid cannot cover, photovoltaic power generation provides reliable power guarantee for residents' lives, agricultural irrigation, communication base stations, etc., improves the quality of life of local residents, and promotes the economic development of remote areas.
