The I PV PV current increases in proportion to the incident irradiance. If the spectrum does not change, the I PV is directly proportional to irradiance I PV = C G G.Then, at a constant temperature, the V OC increases with irradiance logarithmically, as follows from Eq. (18.16). In the case of real cells, the I–V characteristics are influenced by the series resistance R s.
