Abstract
Solar cells efficiency is improved, in a first approach, wherein the anode's “top contact” is relocated to the middle of a three-layer solar cell wafer, permitting maximum sunlight photons to excite free electrons in the anode and p-n junction, without causing obstruction or reflection of sunlight therein. In another embodiment, a rechargeable battery of at least 0.1 v is used, to create forward biasing of electrons in a solar cell, having an impurity level that is less than 99.999999%. The anode and cathode of a silicon base solar cell is doped with more than one element, other than phosphorous and boron, to increase its performance and decrease its manufacturing cost.
