N2 - Photovoltaic properties of double-layer iso-type heterostructures based on pentacene, hexathiopentacene, and lead-phthalocyanine are studied. The heterostructures are prepared by thermal deposition on glass substrates at various substrate temperatures (T s ). Under modulated illumination, the sign reversal is observed in photovoltage spectra of pentacene/lead-phthalocyanine heterostructures deposited at T s = 300 K. The properties of these structures are well described by the van Opdorp model for inorganic iso-type heterojunctions. No sign reversal has been observed in pentacene/lead-phthalocyanine, pentacene/hexathiopentacene, and hexathiopentacene/lead-phthalocyanine heterostructures deposited at T s = 370 K, the magnitudes of photovoltage being higher than those in structures prepared at T s = 300 K.
