“…As shown, increasing CdS up to 20% (by wt) increases J SC continuously. On the other hand, with an increase in the amount of CdS, the surface-to-volume ratio of the nanocomposites increases and due to the limited lifetime of the electron–hole pair, they are separated before recombination . This factor can have opposite effects too because surface defects and dangling bonds can hinder charge transfer and increase recombination .…”

In this work, the one-pot process was employed to synthesize polyaniline/cadmium sulfide hybrid nanocomposite. Herein, for the first time, we report a comprehensive study from the synthesis of the raw materials to the photovoltaic cell performance investigation including the synthesis of the polyaniline/cadmium sulfide hybrid nanocomposite through a one-pot process, a morphology study, the fabrication of a hybrid organic/inorganic solar cell, and the evaluation of the cell performance. To this end, the CdS-to-PANI weight ratio was considered as a key parameter, and 0, 2.5, 5, 10, 15, 20, and 40% were used as the CdS values. FTIR, XRD, and FESEM analyses confirmed that the presence of CdS in the PANI nanotubular network affected the morphology of the hybrid nanocomposite, and changing the CdS-to-PANI ratio tuned the nanotubular network morphology from coarse to fine. UV–visible absorption spectrum studies validated the reduction of PANI bandgap due to the presence of CdS. Likewise, the conductivity of the nanocomposites was also improved compared to neat PANI due to the increasing of charge density. These controlled-morphology nanocomposites were used for organic/inorganic hybrid solar cells based on the configuration of the FTO/ZnO/CdS@PANI/Ag device, and the morphology effects on their performance were investigated. When CdS was incorporated in the PANI nanotubular network, J SC and efficiency increased by, respectively, 4.471 mA·cm–1 and 1.87%. This means a 22-fold increase in J SC and a 1700-fold increase in the solar cell based on 20%CdS@PANI compared to those in the solar cell made with pure PANI. In short, by using the one-pot process, it is possible to hierarchically ensure better control of the morphology of organic and inorganic components, increasing the light absorption edge, reducing the bandgap, and improving the photovoltaic performance of CdS@PANI organic–inorganic hybrid nanocomposites.

The light absorption of a monolayer graphene-molybdenum disulfide photovoltaic (GM-PV) cell in a wedge-shaped microcavity with a spectrum-splitting structure is investigated theoretically. The GM-PV cell, which is three times thinner than the traditional photovoltaic cell, exhibits up to 98% light absorptance in a wide wavelength range. This rate exceeds the fundamental limit of nanophotonic light trapping in solar cells. The effects of defect layer thickness, GM-PV cell position in the microcavity, incident angle, and lens aberration on the light absorptance of the GM-PV cell are explored. Despite these effects, the GM-PV cell can still achieve at least 90% light absorptance with the current technology. Our proposal provides different methods to design light-trapping structures and apply spectrum-splitting systems.
