Phosphorene, a single- or few-layered semiconductor material obtained from black phosphorus, has recently been introduced as a new member of the family of two-dimensional (2D) layered materials. Since its discovery, phosphorene has attracted significant attention, and due to its unique properties, is a promising material for many applications including transistors, batteries and photovoltaics (PV). However, based on the current progress in phosphorene production, it is clear that a lot remains to be explored before this material can be used for these applications. After providing a comprehensive overview of recent advancements in phosphorene synthesis, advantages and challenges of the currently available methods for phosphorene production are discussed. An overview of the research progress in the use of phosphorene for a wide range of applications is presented, with a focus on enabling important roles that phosphorene would play in next-generation PV cells. Roadmaps that have the potential to address some of the challenges in phosphorene research are examined because it is clear that the unprecedented chemical, physical and electronic properties of phosphorene and phosphorene-based materials are suitable for various applications, including photovoltaics.

“…Since phthalocyanines absorb near-infrared light, the effects of addition of silicon phthalocyanine, silicon naphthalocyanine or germanium phthalocyanine to the P3HT:PCBM system were investigated [15][16][17][18][19][20][21]. Solubilized metal phthalocyanines (MPc) could be dissolved in organic solvents, and the application for the device process using a spin-coating method could be expected.…”

“…6(a). The band structure of P3HT and PCBM [30] makes them an ideal donor and acceptor pair. In comparison to P3HT, the energy levels of the conduction and valence bands of CuO and the lowest unoccupied molecular orbital and highest occupied molecular orbital (HOMO) of PCBM are such that CuO and PCBM can form a semiconductor heterojunction; this makes them a suitable donor and acceptor pair.…”

Copper oxide (CuO) is a p-type semiconductor having a band gap energy of 1.5 eV, which is close to the ideal energy gap of 1.4 eV required for solar cells to allow good solar spectral absorption. The inherent electrical characteristics of CuO nanoparticles make them attractive candidates for improving the performance of polymer solar cells (PSCs) when incorporated in the active polymer layer. The incorporation of CuO nanoparticles in P3HT/PC70BM solar cells at the optimum concentration yields 40.7% improvement in power conversion efficiency (PCE). The CuO nanoparticles in the size range of 100-150 nm have an effective average band gap of 2.07 eV. In addition, the X-ray diffraction (XRD) and differential scanning calorimetry (DSC) analyses show improvement in P3HT crystallinity, and surface analysis by atomic force microscope (AFM) shows an increase in surface roughness of the PSCs. The key factors namely photo-absorption, exciton diffusion, dissociation, charge transport, and charge collection inside the PSCs which affect the external quantum efficiency (EQE) and PCE of these cells are analyzed.
