“…This 2D carbon nanomaterial has achieved considerable interest due to the huge mobility of electrons and holes, optical transparency, flexibility, and chemical inertness [ 1 , 2 , 3 ]. Graphene is already considered to be a new transparent conductor [ 4 , 5 ], a monolayer alternative to the Schottky contact metals [ 6 , 7 ], and even an active layer of semiconductor devices [ 8 , 9 , 10 , 11 , 12 ]. Graphene-based transistors [ 8 ], diodes [ 6 , 7 ], photodetectors [ 9 , 10 , 11 ], and solar cells [ 12 , 13 , 14 ] are also meaningful in this context.…”

In this study, graphene was synthesized on the Si(100) substrates via the use of direct microwave plasma-enhanced chemical vapor deposition (PECVD). Protective enclosures were applied to prevent excessive plasma etching of the growing graphene. The properties of synthesized graphene were investigated using Raman scattering spectroscopy and atomic force microscopy. Synthesis time, methane and hydrogen gas flow ratio, temperature, and plasma power effects were considered. The synthesized graphene exhibited n-type self-doping due to the charge transfer from Si(100). The presence of compressive stress was revealed in the synthesized graphene. It was presumed that induction of thermal stress took place during the synthesis process due to the large lattice mismatch between the growing graphene and the substrate. Importantly, it was demonstrated that continuous horizontal graphene layers can be directly grown on the Si(100) substrates if appropriate configuration of the protective enclosure is used in the microwave PECVD process.

In recent years, photovoltaic cell technology has grown extraordinarily as a sustainable source of energy, as a consequence of the increasing concern over the impact of fossil fuel-based energy on global warming and climate change. The different photovoltaic cells developed up to date can be classified into four main categories called generations (GEN), and the current market is mainly covered by the first two GEN. The 1GEN (mono or polycrystalline silicon cells and gallium arsenide) comprises well-known medium/low cost technologies that lead to moderate yields. The 2GEN (thin-film technologies) includes devices that have lower efficiency albeit are cheaper to manufacture. The 3GEN presents the use of novel materials, as well as a great variability of designs, and comprises expensive but very efficient cells. The 4GEN, also known as “inorganics-in-organics”, combines the low cost/flexibility of polymer thin films with the stability of novel inorganic nanostructures (i.e., metal nanoparticles and metal oxides) with organic-based nanomaterials (i.e., carbon nanotubes, graphene and its derivatives), and are currently under investigation. The main goal of this review is to show the current state of art on photovoltaic cell technology in terms of the materials used for the manufacture, efficiency and production costs. A comprehensive comparative analysis of the four generations is performed, including the device architectures, their advantages and limitations. Special emphasis is placed on the 4GEN, where the diverse roles of the organic and nano-components are discussed. Finally, conclusions and future perspectives are summarized.

The electronic and optical properties of Janus Ga2SeTe monolayer are calculated using first‐principles calculations and it is found that it has potential in solar cells. It is found that ultrathin cross‐plane pn‐junctions are obtained by stacking Ga2SeTe structures. The graphene‐Ga2SeTe‐graphene sandwich‐structured solar cells are configured to explore the device performance of Ga2SeTe solar cells. The photocurrent and the power conversion efficiency of the Janus Ga2SeTe solar cells are evaluated. The results show that multilayer Janus Ga2SeTe solar cells give rise to a photocurrent exceeding that of thin‐film silicon devices, indicating that Ga2SeTe is a potential material that could be used in photovoltaics devices.
