Science Buddies: "Ask an Expert"

Are non-silicon solar cells, such as CIGS thin films, doped with anything, like silicon is doped with phosphorus and boron? If not, how is the P/N junction created?

For non-silicon based information search for
the sub-headings of CdTe, GaAs, CIGS, DSSC and OSC

"DSC is a successful attempt to create an anthropological
analogous concept to photosynthesis. The photoreceptor and
the charge carrier are different elements; it is an analogous
situation to that of the photosynthetic process where chlorophyll
absorbs photons but does not participate in charge transfer. This
is contrary to conventional PV cells where a semiconductor
assumes both functions."
