In a solar cell, semiconductors of the p-type and n-type are placed in contact with each other via a conducting wire. In order to generate an electric current, which of the following must be true? A. Light shining on the system must have enough energy to set electrons in motion from the p-type to the n-type semiconductor. B. An external battery must be attached. C. Light shining on the system must have enough energy to set electrons in motion from the n-type to the p-type semiconductor. OD. Light shining on the system will cause oxidation to occur.
How is electrolysis different than typical redox reaction such as those found in corrosion and batteries? A. The half cells involved are only reduction potentials. B. The non-spontaneous chemical reactions are forced to be spontaneous. C. The reactions only lose electrons and therefore are oxidants. OD. The spontaneous reactions produce gaseous elements or compounds.
