Energy policy promoting sustainable development is transforming global energy markets. Solar power, the most abundant of all renewable resources, is crucial to greater achieving energy security and...
The U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO) supports research and development projects that increase the efficiency and lifetime of metal-halide perovskite solar cells, speeding the commercialization of perovskite solar technologies and decreasing manufacturing costs. Perovskites are a family of materials that have shown potential for high performance and low production costs in solar cells. The name “perovskite” comes from their crystal structure. These mater...
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...
Solar energy plays a key role in the clean energy transition. It will contribute to reaching the objectives of the REPowerEU plan and reduce the EU’s dependence on fossil fuels.

Learn solar energy technology basics: solar radiation, photovoltaics (PV), concentrating solar-thermal power (CSP), grid integration, and soft costs.
How Does it Work? ; Alkaline electrolyzers operate via transport of hydroxide ions (OH - ) through the electrolyte from the cathode to the anode with hydrogen being generated on the cathode side. Electrolyzers using a liquid alkaline solution of sodium or potassium hydroxide as the electrolyte have been commercially available for many years. Newer approaches using solid alkaline exchange membranes (AEM) as the electrolyte are showing promise on the lab scale. Solid oxide electrolyzers, which use...

Thermochemical water splitting uses high temperatures—from concentrated solar power or from the waste heat of nuclear power reactions—and chemical reactions to produce hydrogen and oxygen from water. This is a long-term technology pathway, with potentially low or no greenhouse gas emissions. Thermochemical water splitting processes use high-temperature heat (500°–2,000°C) to drive a series of chemical reactions that produce hydrogen. The chemicals used in the process are reused within ...
