When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal. There are several different semiconductor materials used in PV cells. When the semiconductor is exposed to light, it absorbs the light’s energy and transfers it to negat...
The Solar Futures Study is a U.S Department of Energy report that explores the role of solar energy in achieving the goals of a decarbonized grid by 2035 and a decarbonized energy system by 2050.

Following last year’s Russian full-scale war in Ukraine and high energy prices, the EU implemented several emergency measures to guarantee energy supplies for consumers during the critical winter months. Are we as well prepared this year and for the future? How do EU actions on energy security help to ensure EU strategic autonomy? · We are at least as well prepared as last year. Fortunately, the situation has changed a bit. We are no longer purely in an emergency situation, whereas last year...
The DOE solar office addresses some common myths and misconceptions about solar energy and the installation process.
Resilient power systems must be capable of lessening the likelihood of long-duration electrical outages. Solar energy technologies play an important role in strengthening our energy system’s resili...
Harvesting energy from any light source – even a candle – a new generation of ultra-durable and flexible solar cells means devices never need charging. ‘Our grandchildren will laugh that we had cab...
