The study is focused on the distribution of an external electric field and the measurements of the built-in-fields in the donor and acceptor layers within photovoltaic heterostructures. The built-in-fields play an extremely im-portant role in development of organic solar cells, photodetectors, LEDs, transistors, etc. Our investiga-tions are based on the electroabsorption (or Stark spectroscopy) technique. As an example, built-in fields were studied on an organic solar cell heterostructure ITO-CuPc-С60-Al. Two strong built-in fields of oppo-site directions have unexpectedly been found in the bulk of the donor (copper phthalocyanine, CuPc) and acceptor (fullerene, C60) layers under equilibrium conditions. Such a phenomenon has not been observed earlier and owes to the particular accumulation of excess holes trapped at the CuPc / С60 interface.
