Scientists are researching new ways of harnessing the sun’s rays which could eventually make it cheaper for people to use solar energy to power their homes. The experts at Durham University are developing light-absorbing materials for use in the production of thin-layer solar photovoltaic (PV) cells which are used to convert light energy into electricity.

There is a revolution in solar hydrogen on the horizon. The prospect for the wide spread use of hydrogen as a portable energy carrier is dependent on finding a clean, renewable method of production. A research group headed by a professor of electrical engineering is “only a couple of problems away” from developing an inexpensive and easily scalable technique for water photoelectrolysis - the splitting of water into hydrogen and oxygen using light energy — that could help power the proposed hydrogen economy.

Do the overall efficiencies of renewable energy sources add up in terms of their complete life cycle from materials sourcing, manufacture, running, and decommissioning? Using these criteria, researchers have identified the three viable renewable energy resources as solar energy, wind power and geothermal energy.

Like navigating spacecraft through the solar system by means of gravity and small propulsive bursts, researchers can guide atoms, molecules and chemical reactions by utilizing the forces that bind nuclei and electrons into molecules (analogous to gravity) and by using light for propulsion. But, knowing the minimal amount of light required, and how that amount changes with the complexity of the molecule, has been a problem. By creating a quantum mechanical analog of Ulam’s conjecture, researchers have expanded the flexibility and controllability of quantum mechanical systems.
