Photovoltaics hold great potential for addressing the world''s growing energy demand. The Earth receives 120 000 TW of solar power, whereas the global energy consumption is only 15 TW. 1 Yet photovoltaics contribute only 0.04% of the world''s energy production due to the high cost of traditional silicon-based solar cells. 2 To address this …
About Photovoltaic Energy StorageA solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Figure 1. Schematic ...
