We conduct research and development (R&D) in solar power, including photovoltaics and concentrating solar power, to strengthen the U.S. solar industry and improve the manufacturability, reliability, and cost competitiveness of solar energy technologies and systems.
The Sandia Solar Programs e-newsletter features highlights, key activities, events, and publications.


Sandia’s solar photovoltaic (PV) work is focused on developing cost-effective, reliable photovoltaic energy systems and accelerating the integration of PV technology in the United States and globally. The lab’s PV department provides the technical lead for systems integration and balance-of-systems manufacturing technologies as well as technical support to the U.S. Department of Energy (DOE) in deployment and validation of PV systems for federal agencies, utilities, and other institutional users. Sandia assists industry and users by providing technical assistance, accurate performance measurements, component development and improvement, and system evaluation. A major thrust of the department is to evaluate and improve the performance, reliability, and cost effectiveness of systems and balance-of-systems components.

Sandia’s PV research staff work collaboratively with DOE’s Solar Energy Technologies Program, the U.S. photovoltaic industry, other government agencies and national laboratories, and international organizations to increase the worldwide use of PV power systems by reducing cost, improving reliability, increasing performance, removing barriers, and growing markets.

Contributing to the advancement of PV technology through technology development, performance analysis, systems and component characterization, standards development, and industry engagement.

Supporting the development and improvement of solar PV technologies, and providing skilled testing and evaluation of all PV components, including cells, modules, inverters, and balance of system components.

Concentrating Solar Power (CSP)

Concentrating Solar Power (CSP) uses mirrors to concentrate a large area of sunlight, onto a small area. Electrical power is produced when the concentrated light is converted to heat which drives a generator.

In virtually all applications CSP is large power, on the order of 100 MW or larger, that is used by utilities to generate electricity and distribute to consumers. In a CSP plant, solar energy is converted to heat and the heat is used in a conventional power cycle or other heat engine to produce mechanical power and drive a generator.

This unique facility provides experimental engineering data for the design, construction, and operation of unique components and systems in proposed solar thermal electrical plants; planned for large-scale power generation. At 200 feet tall, the NSTTF’s distinct height advantage along with its heat capabilities, offers a unique and complete testing environment to government contractors and agencies, research institutes, universities and private companies.

MEPV concepts use microdesign and microfabrication techniques to produce miniaturized solar cells that are released into a solution similar to printing ink. This solution is then placed or ‘printed’ onto a low-cost substrate with embedded contacts and microlenses for focusing sunlight onto the cells. Sandia’s approach uses cells that are tiny in both thickness and lateral dimensions – as small as 14 microns thick and 250 microns wide. The thinness of the cells reduces material costs while enhancing cell performance by improving carrier collection and potentially achieving higher open circuit voltages.
