Please answer the following question: What is the final step of the following process: -  A photovoltaic cell is created with two layers of semiconductor material - The top layer are &#x27;doped&#x27; with impurities to allow a negative charge - The bottom layer are &#x27;doped&#x27; to allow for a positive charge - This produces an electric field that allows electrons to flow from negative to positve - Sunlight enters the cell - Energy from sunlight knocks electrons loose in both fields - This prevents the flow of electrons from negative to positive - Adding an external circuit allows the exchange to continue
A:
Give the cells owner a flow of electricity.
