The Cell. Nearly all voltaic cells have the same basic components: anode, cathode, salt bridge, wire, and two reaction vessels. The designs vary, but the basic idea is the same. The reaction vessels, or half-cells, will each contain one of the half-reactions. In each vessel, both the reactants and products of the half-reaction will be present.
Photovoltaic Cell: Photovoltaic cells consist of two or more layers of semiconductors with one layer containing positive charge and the other negative charge lined adjacent to each other.; Sunlight, consisting of small packets of energy termed as photons, strikes the cell, where it is either reflected, transmitted or absorbed.
To determine the overall voltage of a particular voltaic cell, simply combine the voltages of the oxidation and reduction half reactions. Even if you need to take a multiple of a half reaction for the electrons to cancel, do not take the multiple of the E 1/2 e the values directly as is from Table (PageIndex{1}) - Standard Reduction …
