Special Issue Information

Dear Colleagues,

In the last decade, the development of novel nanomaterials and low-dimensional systems has become a subject of intensive research, due to high market requirements for innovative applications in virtually all aspects of life. In particular, the field of photovoltaics has witnessed great scientific progress in the last few years, mainly because solar energy has great potential to meet the needs of society in the context of energy crisis the world is facing today. In this case, significantly increasing the photo-absorption area or providing rapid and more efficient charge collection pathways are unique effects unveiled at nano-scale that could be competitively exploited to design solar cell architectures with improved performances and extended functionality, while potentially maintaining small device dimensions and inherently low manufacturing costs.

The first volume of this Special Issue of Nanomaterials, entitled “Advances in Nanomaterials for Photovoltaic Applications”, was a great success among the scientific community, gathering twelve high-quality publications in less than a year, undergoing an efficient and rigorous peer-review process with an average waiting time to the first decision of less than two weeks. Therefore, considering the increasing interest in this topic among researchers, a second volume of this Special Issue is now open to contributions, focusing on theoretical and experimental studies that report on the innovative processing and characterization of nanostructured materials engineered for photovoltaic applications. Papers reporting progress in the development of solar cells relying on nanostructured building blocks are also welcome.

Topics of interest include, but are not limited to, the following:

  • Solar cells based on organic and inorganic thin films, bulk heterojunctions (including non-fullerene-acceptor-based), dye sensitizers and hybrid multi-layered nanostructures;
  • Innovative processing technologies of organic and inorganic nanomaterials, in addition to other new multi-compound and multi-phase nanocomposites;
  • Examination of the structural, morphological, optical, electrical and other properties of nanomaterials important for photovoltaic applications;
  • Correlation of nanomaterials’ functional properties with their aspect and morphology, chemical composition, micro- and nanostructure, as well as preparation methods;
  • Theoretical and computational studies aiming at predicting various properties of nanomaterials used as functional constitutive elements within photovoltaic devices.

InAs doping superlattice-based solar cells have great advantages in terms of the ability to generate clean energy in space or harsh environments. In this paper, multi-period InAs doping superlattice solar cells have been prepared.. Current density–voltage measurements were taken both in the dark and light, and the short-circuit current was estimated to be 19.06 mA/cm2. Efficiency improvements were achieved with a maximum one sun AM 1.5 G efficiency of 4.14%. Additionally, external quantum efficiency and photoluminescence with different temperature-dependent test results were taken experimentally. The corresponding absorption mechanisms were also investigated. Full article

Solution-processed cadmium telluride (CdTe) nanocrystal (NC) solar cells offer the advantages of low cost, low consumption of materials and large-scale production via a roll-to-roll manufacture process. Undecorated CdTe NC solar cells, however, tend to show inferior performance due to the abundant crystal boundaries within the active CdTe NC layer. The introduction of hole transport layer (HTL) is effective for promoting the performance of CdTe NC solar cells. Although high-performance CdTe NC solar cells have been realized by adopting organic HTLs, the contact resistance between active layer and the electrode is still a large problem due to the parasitic resistance of HTLs. Here, we developed a simple phosphine-doping technique via a solution process under ambient conditions using triphenylphosphine (TPP) as a phosphine source. This doping technique effectively promoted the power conversion efficiency (PCE) of devices to 5.41% and enabled the device to have extraordinary stability, showing a superior performance compared with the control device. Characterizations suggested that the introduction of the phosphine dopant led to higher carrier concentration, hole mobility and a longer lifetime of the carriers. Our work presents a new and simple phosphine-doping strategy for further improving the performance of CdTe NC solar cells. Full article
