The Photovoltaics (PV) team works to improve efficiency and reliability and lower manufacturing costs of PV panels, with an overall goal of driving down the cost of electricity from solar photovoltaic technologies. The team funds innovative concepts and experimental designs across a range of materials that have the potential to make solar energy among the least expensive forms of electricity.

Dr. Lenny Tinker is the program manager for the Photovoltaics team. He has been at the U.S. Department of Energy Solar Energy Technologies Office (SETO) since September 2011 and started as an AAAS Science and Technology Policy Fellow on the Photovoltaics team working on Incubator Round 6. As a Federal employee, he now manages early-stage applied research and development programs at national labs, universities, and companies to develop advanced photovoltaic systems. Dr. Tinker is also the SETO Fellowship coordinator and is the SETO representative on the IEA PVPS Executive Committee.

Prior to his position in the Energy Department, Dr. Tinker was an Alexander von Humboldt Postdoctoral Fellow at the Westfälische Wilhelms-Universität in Münster, Germany, where he designed inorganic complexes to be used in organic light emitting diodes and to promote triplet-triplet upconversion processes. Dr. Tinker obtained a Ph.D. in chemistry from Princeton University and a B.S. from Beloit College. His Ph.D. research focused on visible light-induced water reduction using iridium(III) chromophores and colloidal catalysts to produce a portable fuel using sunlight.
