Description : A solar cell is a solid state device that converts the energy of sunlight directly into electricity by thephotovoltaic effect. Assemblies of cells are used to make solar modules, also known as solar panels. The energy generated from these solar modules, referred to as solar power, is an example of solar energy.

THE SOLAR CHALLENGE

• With a projected global population of 12 billion by 2050 coupled with moderate economic growth, the total global energy consumption is estimated to be ~28 TW. Current global use is ~11 TW.
• To cap CO2 at 550 ppm (twice the pre-industrial level), most of this additional energy needs to come from carbon-free sources.
• Solar energy is the largest non-carbon-based energy source (100,000 TW).
• However, it has to be converted at reasonably low cost.
