Solar energy is one of the most abundant sources of clean renewable energy and is also an important source of electrical energy. Solar energy has the potential of meeting all of the world\u27s energy needs, and has seen substantial growth and development in recent years. Solar cells can convert sunlight directly into electrical energy, and the solar industry has made a great deal of progress in making them less costly and more efficient. The conversion efficiency of solar cells, however, is one of the main factors that limits the solar industry from competing with fossil fuels. Once the efficiency of solar cells is improved, solar energy will have a greater impact on the worlds energy consumption, and hence more clean energy will be consumed
