Breakthrough In Perovskite Solar Cells

MIT Technology Review recently published a summary article showing,
. . . Perovskite bringing down the cost of solar cells significantly.

Materials researchers in Oxford, led by Dr Henry Snaith,
. . . have recently shown that they can make simple perovskite solar cells,
. . . with efficiencies pushing 20%, which makes them competitive with,
. . . existing commercial silicon solar cells,
. . . while the material is dirt cheap.
They are also more suitable for incorporating into roofing materials and
. . . glass panels than silicon, and so have the clear potential of being,
. . . as fundamental to our city architecture as steel, concrete and asphalt.
In other words, they could well be the materials that will make it possible,
. . . to collect the solar energy we need,
. . . at a cost that can compete with fossil fuels.
