1.2 A Brief History of Solar Cells. A solar cell, also known as a photovoltaic (PV) cell, harvests sunlight and transfers the energy into electricity by the photovoltaic effect. The term “photovoltaic” is based on the Greek word phos (meaning “light”) and the word “voltaic” (meaning “electric”), which comes from the name of the Italian physicist Alessandro Volta, after whom the
Bell Labs developed the first practical solar cell using silicon, a semiconductor. This solar cell had an efficiency rate of around 6%, a significant improvement over Fritts'' cells. 1960s: The space age saw the use of solar cells
Solar cell technology has clearly come a long way from silicon wafer-based cells to the latest "emerging" solar cell technologies. These advancements will no doubt play an important role in reducing carbon foot print and finally achieving the dream of a sustainable energy resource. Nano-crystal QD based technology has a theoretical potential of turning more than 60% of the total

The present authors began working in the solar field in the early 1970s. This was the period of the Arab oil embargo and the first gas lines in the USA. There were several new technical successes in this period including the demonstration of 20% efficiency single-crystal AlGaAs/GaAs solar cells for space [12, 13].
Deviating from the single-crystal theory foundation for solar cells, Carlson and Wronski fabricated the first amorphous silicon solar cell in 1976 . While the conversion efficiency was low, the ability to add voltages in monolithic structures led to the amorphous silicon-powered calculator in 1978 powered by room light .
