“…A large number of theoretical studies have been reported for heterostructure solar cells. Band‐gap matching is an efficient strategy for exploring the possibilities of phosphorene in photovoltaics, which saves time and materials as compared to trial‐and‐error experimental processes . For instance, bilayer phosphorene/MoS 2 heterostructures have a theoretical conversion efficiency of up to 18%, which exceeds that of graphene/ transition metal dichalcogenide (TMDC) counterparts .…”

Black phosphorus was first synthesized by Bridgman in 1914 [1] but has been less intensively studied in the past century due The successful isolation of phosphorene (atomic layer thick black phosphorus) in 2014 has currently aroused the interest of 2D material researchers. In this review, first, the fundamentals of phosphorus allotropes, phosphorene, and black phosphorus, are briefly introduced, along with their structures, properties, and synthesis methods. Second, the readers are presented with an overview of their energy applications. Particularly in electrochemical energy storage, the large interlayer spacing (0.53 nm) in phosphorene allows the intercalation/deintercalation of larger ions as compared to its graphene counterpart. Therefore, phosphorene may possess greater potential for high electrochemical performance. In addition, the status of lithium ion batteries as well as secondary sodium ion batteries is reviewed. Next, each application for energy generation, conversion, and storage is described in detail with milestones as well as the challenges. These emerging applications include supercapacitors, photovoltaic devices, water splitting, photocatalytic hydrogenation, oxygen evolution, and thermoelectric generators. Finally the fast-growing dynamic field of phosphorene research is summarized and perspectives on future possibilities are presented calling on the efforts of chemists, physicists, and material scientists

Herein, the first paper for preparing Cu2ZnSnS4 film using EDTA as a complex agent by one-step hydrothermal method. The efficient Molybdenum oxide (MoO3) layer was also grown by the same step as preparing the Cu2ZnSnS4 film. The effects of different copper concentrations on the structural, optical, and electrical properties were studied. X-ray diffraction and Raman analyses confirmed the formation of polycrystalline kesterite phase Cu2ZnSnS4 films with preferred orientation along (112) plane and showed that structure property alters with copper concentration: at lower copper concentration single kesterite phase Cu2ZnSnS4 was formed, while with increasing copper concentration kesterite Cu2ZnSnS4 and secondary phases were formed. Field emission scanning electron microscopy revealed a mixture of micro-flower and a thin network of nanoflakes morphology. In addition, it showed as copper concentration changes the grain size of micro-flower and thickness of flakes change. UV-visible analysis showed high and broad absorbance spectra with high absorption coefficient values of more than 104 cm−1 in visible and infrared regions.also, predicted the band gap of single-phase Cu2ZnSnS4 film equal to 1.4 eV. Photoluminescence analysis demonstrated a single emission peak located at 1.55 eV which is quite near to the band gap of kesterite Cu2ZnSnS4. Hall measurement showed the single phase sample is a p-type semiconductor with a resistivity of 5 Ω cm, a charge carrier concentration of 7.5 × 1016 cm−3 and mobility of 16 cm2 Vs−1. Finally, a heterojunction solar cell was made with Mo foil/MoO3/CZTS/Zn0.35Cd0.65S/ZnO/Al configuration. A photovoltaic conversion efficiency of (2.17%) was attained under 100 mW cm−2 with an open-circuit voltage of (0.432) V, short-circuit current density of (13.4) mA cm−2 and a fill factor of (37.5%).

Cu2ZnSnS4 (CZTS) is one of the promising materials of absorber layer used in thin film solar cells. In this paper, we revealed the effects of surface treatment by hydrogen peroxide solution on the chemical and structural properties of CZTS thin films in order to improve the conversion efficiency. On the Raman spectra, the full width at half maximum (FWHM) of A1 peak at around 338 cm−1 is not affected by H2O2 solution treatment. However, Raman scattering spectroscopy results showed that the existence of not only CZTS but also oxide was confirmed by the H2O2 solution treatment. From the XPS spectra, Zn, and S were dissolved by H2O2 solution. The surface oxidation takes place in a very short period of time. The sulfate phase is existence on the CZTS surface by H2O2 surface treatment.
