Popis: A new structure incorporating multiple phases of chloroindium phthalocyanine (ClInPc) is fabricated and tested in photovoltaic devices. This so-called heteromorphic structure includes as-deposited and THF vapor treated ClInPc films to improve absorption and photovoltaic (PV) performance in devices. Absorption of the polymorphic phases of ClInPc are complementary and lead to improved current generation. Short circuit current is improved by over 70% using the heteromorphic structure, while power conversion efficiency (PCE) improves by more than 40% versus solely as-deposited devices. Advantages of the heteromorphic structure include broader spectral response, improved interfacial contact area and an intermediary open circuit voltage (Voc).
