Implemented as part of CH350 lab course at Northwestern in spring semester 2015. On day 1, students fabricate perovskite solar cells, assemble into solar panels, and produce electricity under sunlight. On day 2, students characterise the active layer (XRD, electron microscopy) and device performance (currentvoltage curve).

Perovskites will bring a revolution in how we produce energy. How do they work? What potential do they have?
The intro to this Talk has been performed by the artists of Capitol Musical Theatre (http://www.teatrcapitol.pl/). Olga Malinkiewicz is a star amongst young Polish enterpreneurs and scientists. In her work she is addressing the very real problem of energy sustainability. Olga is the CTO and cofounder of Saule Technologies, Polish startup company, one of the global forerunners in the commercialization of thinfilm perovskite solar cells. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
Perovskites: Ancient Structure, Modern Applications
Goodfellow is pleased to announce the availability of their new range of Perovskites, a group of materials that demonstrate great potential for optoelectronic applications.
Perovskites have a unique and versatile crystal structure that consists of a variation in the chemical formula ABX3. Many Perovskites occur as oxides (ABO3), where A and B are typically metal cations. Due to their lattice, these materials are characterized by special properties like superconductivity, magnetoresistance, piezoelectricity and dielectric and pyroelectric behavior.
Therefore, Perovskites are excellent candidates for multilayer capacitors like fuel cells, solar cells, sensors and electric batteries, or even nextgeneration display screens, LEDs, memory devices (RAM) and hightemperature superconductors.
Goodfellow’s range of Perovskites includes powder and solid forms of:
Bismuth Titanium Oxide
Copper Tungsten Oxide
Lead Titanium Oxide

The World s Largest Diamond Price, Owned by Queen Elizabeth II
Scientists have discovered an unprecedented sample of a rare diamond from the bowels of the Earth called davemaoite.
The discovery comes after leading geophysicist Hokwang (Dave) Mao discovered a neverbeforeseen sample of the diamond mineral using a special technique.
This diamond is the first example of perovskite calcium silicate (CaSiO3) found on Earth’s surface. The reason, this diamond can only be produced in highpressure areas in the bowels of the Earth.
Another form of CaSiO3, known as wollastonite, is found throughout the world. But davemaoite is different, in that it has a special crystal structure that can only form under high pressure and high temperature in the earth’s core.
Davemaoite has long been thought to be the most abundant and important geochemical constituent of the Earth’s core. The International Mineralogical Association has now confirmed davemaoite is a new mineral form.
The discovery of davemaoite suggests that diamonds could form further in the Earth’s core than previously thought. This suggests that the Earth’s core may be the best place to look for more new minerals, according to the Space report.
