Scientists have taken a promising step toward the goal of generating a new source of clean energy, using little more than sunlight and water.

US chemists have perfected a simple way to make tiny copper nanowires that are ideal for thin-film solar cells, flat-screen TVs and computers, and flexible displays.

An alternative method of making light-sensitive semiconductors could lead to high-efficiency solar cells, better night-vision cameras and a host of other applications.

A US university has received a patent for a solar-cell technology that uses millions of tiny plastic fibers that capture more light and have double the energy production of today’s flat cells at a fraction of the cost.

Vertical nano crystals of silicon that capture as much as 85 percent of the full spectrum of incoming sunlight might slash the cost of photovoltaic cells.

In a few decades human and machine will merge, illness will be eradicated, and human beings will live to 150. Take a journey into the imaginations of scientists and futurists pondering ways to use nanotechnologies, and discussions about how society should or could use them.

We can convert CO2 into a useable fuel and go some way to solving energy storage problems for renewable energy – and reduce greenhouse gas at the same time. Very cool

A Monash University-led international research team has produced solar cells three times more efficient than the equivalent type of cells.

Amorphous-silicon solar cells patterned with nanoscale domes absorb more light, and shed water and dust.

Nano silver in polymer semi-conductors can boost the materials’ generation of electrical current taking us a step closer to lighter, cheaper, and more-flexible solar cells.
