photovoltaic
Meaning: Relating to the conversion of light energy into electrical energy; describing solar cells or panels that generate electricity from sunlight.
Photovoltaic (PV) technology is the most common form of solar energy generation. PV cells are made from semiconductor materials, typically silicon, which generate an electric current when exposed to light. The technology is central to renewable energy strategies worldwide. Photovoltaic panels can be installed on rooftops, in solar farms, or integrated into building materials. Common collocations include 'photovoltaic cell,' 'photovoltaic panel,' 'photovoltaic system,' and 'photovoltaic energy.'
Examples
- The government announced subsidies for homeowners installing photovoltaic panels on their rooftops. 政府宣布为在屋顶安装光伏面板的房主提供补贴。El gobierno anunció subvenciones para los propietarios que instalen paneles fotovoltaicos en sus tejados.政府は屋根に太陽光パネルを設置する住宅所有者への補助金を発表した。정부는 옥상에 태양광 패널을 설치하는 주택 소유자에 대한 보조금을 발표했다.
- Advances in photovoltaic technology have dramatically reduced the cost of solar energy over the past decade. 光伏技术的进步在过去十年间大幅降低了太阳能的成本。Los avances en tecnología fotovoltaica han reducido drásticamente el coste de la energía solar en la última década.太陽光発電技術の進歩により、過去10年間で太陽エネルギーのコストは劇的に低下した。태양광 발전 기술의 진보로 지난 10년간 태양에너지 비용이 극적으로 감소했다.
- The new building incorporates photovoltaic cells into its glass façade to generate electricity. 新建筑将光伏电池整合到其玻璃幕墙中以发电。El nuevo edificio incorpora células fotovoltaicas en su fachada de vidrio para generar electricidad.新しい建物はガラスのファサードに太陽光発電セルを組み込み、電力を生成している。새 건물은 유리 파사드에 태양광 셀을 통합하여 전기를 생산하고 있다.
