For one, molybdenite is a two-dimensional material, meaning it is less voluminous than three-dimensional silicon. Electrons can move around as freely in a 0.65-nanometer-thick sheet of molybdenite as they can in a 2-nanometer-thick layer of silicon, ostensibly requiring roughly one third the space to accomplish similar ends. It also possesses an ideal “gap” for turning transistors on and off, meaning a transistor with molybdenite’s 1.8 electron-volt gap could consume 100,000 times less energy than its silicon counterpart.
Further, molybdenite contains the necessary band gap needed to control semiconductors’ material properties. Electron-free spaces between these “band gaps” that allow certain electrons to leap across lend a greater level of control over a material’s electrical properties. Molybdenite has this gap. Graphene does not, making it less-than-ideal for transistor applications
A solar panel just a few inches square, would in theory be able to power a home...
SCIENTISTS have created the world’s brightest light and will use it to look at molecules and atoms in more detail than before. The beam, made of synchronic light — created when electrons are fired in a vacuum along a circular tube at close to the speed of light — is almost 100 billion times brighter than the Sun and will be the light source of a £373million “giant microscope”, the Diamond project, being built in Didcot, Oxfordshire.

Wow, this is crazy.
Molybdenite is used as a dry lubricant(bearings, aircraft engines, ski glide wax, ...).
The guys from Berkeley Lab are using titanium dioxide as a very efficient photocatalyst(www.abovetopsecret.com...).

A sunlight concentrator, either a Fresnel lens affair or a parabolic trough/dish effort shining the concentrated light onto the panel should do it.
Scientists claim that a new method for creating materials in sheets that are just one-atom-thick could lead to breakthroughs in data and energy storage technologies, meaning bigger storage devices and longer-lasting batteries.
According to coverage of the discovery over on Reuters, quoting a report published in journal Science, the technique makes it significantly easier to create one-atom-thick sheets of different materials, including graphene sheets made from carbon.
