When the sun shines on photovoltaic cells
they produce DC direct current electricity
of about 0.5 volts on each cell.
Adding up many solar cells you can produce
any Volt amount of solar electricity.

Use free energy from the sun:

Heat (hot water, building heat, cooking)
Electricity generation (photo voltaic, heat engines)
Desalination of seawater.

Many scientists work on new solutions Were you aware that a North Carolina State University staff has demonstrated that water gel-based solar devices (known as: "artificial leaves") can work like solar cells to generate electricity? The analysis has been released on-line within the Journal of Materials Chemistry by Doctor. Orlin Velev, an Invista Professor of Chemical and Bio-molecular Engineering. The results prove the idea for making solar cells that more closely mimic nature. They also have the possibility to be less costly and more environmentally friendly than the recent standard silicon based solar cells. The bendable products are composed of water-based gel infused using light-sensitive molecules (like plant chlorophyll) coupled with electrodes coated by carbon materials, such as carbon nanotubes or graphite. Graphene is the fundamental structural element of a number of carbon allotropes including graphite, carbon nanotubes and fullerenes. Graphene is a 1-atom thick planar sheet of carbon atoms that are densely packed in a honeycomb crystal lattice. The name comes from graphite ene; graphite itself consists of many graphene sheets stacked together. The light-sensitive molecules get "excited" by the sun's rays to create electricity, similar to plant molecules that get excited to synthesize sugars in order to grow. Dr. Velev affirms that the research team hopes to be able to "learn how to mimic the materials through which nature harnesses solar energy." Although synthetic light-sensitive molecules can be used, Velev says naturally made products, like chlorophyll, are also very easily integrated in these products because of their water-gel matrix. Velev even imagines a future in which homes could be covered with soft sheets of similar energy-generating artificial-leaf solar cells. The concept of biologically inspired 'soft' units for generating electricity might in the future provide an alternative for the present-day solid-state technologies.
