bosphorus is mixed into one like it has 5 electrons in its outer shell one too many which can orbit for. the 2nd layer is mixed with boron which has only 3 out electrons one to feel. that means the layer has gaps which attract the excess phosphorus electrons this creates a flow of negatively charged electrons from one layer to the other one layer loses electrons and becomes positive the other gains electrons and becomes negative creating 2 poles eventually all the gaps on the surface of the layers. occupied the whole and the electrons are now to flora plant to migrate that's where the sun comes in when some light hits the surface layer he splits off one unit making a hole under so close election. the electron is attracted to the positive and the home goes another electron from another down to replace the one longs which in turn is split off inside. the electrons which of the right at the positive pole return via one head to the negative that's an electric car. and it flows as long as the sun shines. if solar energy is to enable commercial aviation and satisfy our electricity needs in th
