Problem: Given the 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 'doped' with impurities to allow a negative charge - The bottom layer are 'doped' 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
