Interface modification of organic photovoltaics by combining molybdenum oxide (MoOx) and molecular template layer

Improvement of Cochineal Extract (Dactylopius coccus Costa) Properties Based on the Green Synthesis of Silver Nanoparticles for Application in Organic Devices

“…e interest in this area is to obtain new organic compounds with improved, more efficient properties for the manufacture of organic, light-emitting diodes (OLEDs) [1], organic photovoltaic cells (OPVs) [2,3], and thin film transistors (TFTs) [4]. e biosynthesis of new hybrid structures using natural organic compounds for development of photoreactive compounds is straightforward and significantly reduces the cost of organic devices.…”

Improved photovoltaic response of a near-infrared sensitive solar cell by a morphology-controlling seed layer

“…Tuning the organic film crystallinity, molecular orientation and aggregation by a templating layer toward better performance of organic solar cells has been drawing interest. The templating layers are focused on semiconducting organic molecules [37][38][39] and copper halide. 33,35,[40][41] However, organic templating materials would cause competent light absorption, as well as additional interfacial energetics to be concidered.…”

Interface modification for organic and perovskite solar cells

“…Focusing on the interface issues of OSCs and PSCs, our group has been carrying out the research, and some interesting results have been obtained [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. We are hopeful to achieve two aims through the interface study.…”

“…The other is that the thickness-independent interface layer can be processed by large-scale printing techniques for large-area, highly efficient OSCs and PSCs. Herein, this review will summarize recent research progress on OSCs and PSCs using interface Interface modification for small molecular solar cells using molecular template layer Thin film morphology and molecular orientation are very important to the charge transport and device performance, and molecular template growth has been developed to fabricate high-quality organic semiconductor thin film with controllable morphology and molecular orientation [25,27,28,34]. In order to form ordered bulk heterojunction instead of planar heterojunction, the combination of molecular template growth and glancing angle deposition technique was used to fabricate ordered nanocolumn-array phthalocynine organic semiconductor thin film with controllable molecular orientation, in which a controllable lying-down molecular orientation was obtained in the models of planar molecule copper phthalocynine (CuPc) and non-planar molecule chloroaluminum phthalocyanine (AlClPc) [28], as shown in Fig.…”

“…Thus molybdenum oxide (MoOx) can be inserted to tune the energy levels between the electrode and the active layer. The combination of MoOx and molecular template layer PTCDA as the interface modification layers in small molecular solar cells results in the obvious improvement for both Voc and Jsc, as well as the great enhancement in PCEs [34,49], as summarized in Table 1. The insertion of a MoOx layer as the HTL can lead to the improvement of the Voc due to the large difference in work function between the MoOx and the active layer materials, which would cause significant band-bending and enhance the built-in field.…”
