“…This indicats that nanoclusters sensitized films shows better resistance to photocorrosion. This can be attributed to that the higher efficiency in polysulfide electrolyte is preferred to inhibit photocorrosion of CdS and PbS nanoclusters [28]. As well known, the degradation efficiency of pollution after UV irradiation can be described by Lambert-Beer Law [29] and Langmuir-Hinshelwood model [30], that is, equation (2):…”

“…Hence, PED-NW arrays grown on PED 2D seed layers were further used as the photocathode to construct the inverted IR photovoltaic device. 36 This was solved by renewal of the growth solutions, and 500 nm thick PbS layers were deposited at 50 °C using three solution renewals (Figure 4c, d). Complete coverage was achieved after 24 hr at 5 °C, with layer thickness of ca.…”

Interfacial energy band alignment is crucial for applications involving charge transfer and transport. Specifically, efficient photovoltaic (PV) devices require fine tuning of the energy levels at interfaces between the absorber and the electrodes for extraction of photogenerated charges. Infrared (IR) absorbers have a small bandgap, hence such tuning is difficult using common electrode materials. Semiconductor sensitized PV devices typically utilize transparent metal oxide photoanodes, since many semiconductor absorbers can inject photoexcited electrons into their conduction bands. Transparent photocathode electrodes, to which photoexcited holes are transferred from semiconductor absorbers, are less common.Transparent nanostructured photocathodes with beneficial energy level alignment with small bandgap semiconductors can widen the material choices for IR photoelectrodes. Herein we show that CuSCN nanowire (NW) arrays can serve as such photocathodes, with efficient transfer of photogenerated holes from bulk-like PbS absorbing in the IR and near-IR range.Pulsed electrodeposition was used to fabricate high-quality CuSCN NW arrays. Significant NIR and IR photocurrents showed that the CuSCN NW array is an efficient photocathode for PbS sensitized IR photovoltaic devices. Comparison of various electrode materials verified the photogenerated hole injection vs. competing processes such as electron injection and recombination, and suggested that this material system can be used for studying photosensitized hole injection from other small bandgap semiconductors.

PbS thin films were grown on glass substrates by chemical bath deposition (CBD) using lead nitrate, thiourea and sodium hydroxide in aqueous solutions at three different temperatures (22, 36 and 50 C). The microstructure and morphology evolution of the films were investigated using X-ray diffraction, scanning electron microscopy and atomic force microscopy. Optical properties were studied using UV-Vis-IR spectroscopy. The results indicate that temperature plays an important role in controlling the morphology and optical properties of nanostructured PbS thin films through changing deposition mechanism. The active deposition mechanism changed from cluster to ion-by-ion mechanism with an increase in deposition temperature from 22 to 50 C, and consequently, film properties such as morphology, optical absorption and preferred orientation changed completely.
