“Black Silicon” Could Change Solar Energy Generation

Recently was discovered a new material named “black silicon” which could be used to change the solar energy technology because in comparison with conventional silicon is between 100 and 500 times more sensitive to light.
Look how this material was discovered: a team of scientist from Harvard University, before adding sulphur hexafluoride, they shone an ultra-powerful laser on a silicon wafer. The result was amazing, a silicon wafer that looked black to the naked eye, then this silicon was examined under a microscope where was discovered that it is covered with a massive amount of ultra-tiny spikes.
Because this material (black silicon) is very sensitive to light, it can be used in infra-red imaging systems and night vision. In the near future this substance will be available and will change radical the solar energy generation.
