Lifetime measurements by open circuit voltage decay in GaAs and InP diodesMinority carrier lifetimes in the base of solar cells made on GaAs and InP were measured by the open-circuit voltage decay method. The measurement technique and the conditions under which the minority carrier lifetimes can be measured are described. Minority carrier lifetimes ranging from 1.6 to 34 ns in InP of different doping concentrations were measured. A minority carrier lifetime of 6 ns was measured in n-type GaAs, which agrees well with the lifetime of 5.7 ns measured by transient microwave reflection.
