Solar cell. Close-up of a high performance solar cell made from a monocrystalline silicon wafer. The contact grid is made from busbars (large strip) and fingers (small strips). When light hits it it releases electrons,which are converted into an electrical current. A grid of wires collects the electrons. Solar power is an environmentally-friendly energy source. It does not use up limited resources and does not release toxic waste products | |
