Perovskite-Based Solar Cells Gaining in Efficiency

Facebook X LinkedIn Email
GOLDEN, Colo., April 29, 2014 — Perovskites are showing promise as materials for a new generation of highly-efficient, low-cost solar cells. A team from the US Energy Department’s National Renewable Energy Laboratory (NREL) is studying the perovskite (CH3NH3)PbI3 to determine its effectiveness and potential applications in conjunction with titanium dioxide film of varying thickness. A semiconducting cube-like mineral, (CH3NH3)PbI3 has the same crystal structure as the mineral perovskite discovered in Russia’s Ural Mountains nearly 200 years ago. Researchers have also found it easy to fabricate the...Read full article

    perovskite
    The term perovskite refers to a specific crystal structure commonly found in various materials. Perovskite structures have a cubic arrangement of oxygen ions, forming a framework within which other cations (positively charged ions) are located. This crystal structure was named after the mineral perovskite, which has the chemical formula CaTiO3 and was first discovered in the Ural Mountains of Russia. The general formula for the perovskite structure is ABX3, where: A represents a larger...
