Scientists develop silicon cells capable of absorbing infrared radiation from the sun
Researchers have developed a silicon photovoltaic cell capable of turning infrared radiation into electricity. The sun is an inexhaustible source of energy which well-exploited, could solve many of the energy suply problems we have today. The photovoltaic cell, commonly known as solar cell, is a device capable of turning solar light into electricity. However, there are many obstacles that prevent a massive use, such as a relatively high cost (0.02 euros per watt generated) and the low efficiency of silicon based solar cells, around 17 per cent.
