Abstract
We ascribe the relaxation of the open circuit voltage in Cu(In,Ga)Se-2 heterojunction solar cells to persistent photoconductivity in the abs orber material. The experimentally observed increase of the open circu it voltage during illumination is accompanied by an increase of the ju nction capacitance resulting from an effective increase of the space c harge density by persistent trapping of photogenerated electrons.
