Special Issue Information

Dear colleagues,

The Guest Editor is inviting submissions for a Special Issue of Energies on the subject area of “Advanced Polymer and Perovskite Solar Cells".

Polymer solar cells were considered a unique alternative to traditional inorganic solar cells until the sudden emergence of perovskite solar cells. A perovskite boom has occupied most researchers working on photovoltaics, even including polymer solar cells, leading to a drastic efficiency increase from 10% to 25% within the last 10 years. With the great success of perovskite solar cells, polymer solar cells have appeared to fade from core research areas. In 2017, an unexpected counter-attack surprisingly came from polymer solar cells with an unprecedentedly high efficiency of 13% at the time, and the efficiency keeps increasing, now reaching over 16%, which sheds new light on the polymer solar cell area, attracting again the researchers who moved to perovskite solar cell area. In this Special Issue, we would focus on any relevant energy conversion applications based on organic and perovskite materials, which could promote mutual developments of both solar cell research areas. Topics of interest for publication include, but are not limited to the following:

  • Organic solar cells
  • Polymer solar cells
  • Nonfullerene-based organic solar cells
  • Nonfullerene-based polymer solar cells
  • All polymer solar cells
  • Organic-inorganic perovskite solar cells
  • Inorganic perovskite solar cells
  • Tandem solar cells
  • Hybrid tandem solar cells
  • Multi-junction solar cells
  • Solar cell modules
  • Large area solar cells
  • Multi-functional devices
  • Integrated devices

Polymer solar cells (PSCs) based on non-fullerene acceptors have the advantages of synthetic versatility, strong absorption ability, and high thermal stability. These characteristics result in impressive power conversion efficiency values, but to further push both the performance and the stability of PSCs, the insertion of appropriate interlayers in the device structure remains mandatory. Herein, a naphthalene diimide-based cathode interlayer (NDI-OH) is synthesized with a facile three-step reaction and used as a cathode interlayer for fullerene and non-fullerene PSCs. This cationic polyelectrolyte exhibited good solubility in alcohol solvents, transparency in the visible range, self-doping behavior, and good film forming ability. All these characteristics allowed the increase in the devices’ power conversion efficiencies (PCE) both for fullerene and non-fullerene-based PSCs. The successful results make NDI-OH a promising cathode interlayer to apply in PSCs. Full article

In perovskite photovoltaics (PSCs), the role of the hole transporting material (HTM) is highly important as it significantly influents to the global device’s performance and stability. Hole transporter ensures the extraction of hole at the perovskite/HTM interface and transport it towards the cathode. Thus, accurate molecular design affording to efficient and cost-effective HTM is of major interest. Small molecules having glass forming property is an attractive class as it can form morphologically stable thin film. Herein, a carbazole molecular glass bearing a polymerizable function was designed and synthetized. Its characteristics are suitable for application as HTM in PSCs. The preliminary photovoltaic application lead to device efficiency of 14–15% depending on the chemical composition of the perovskite employed. These promising results open the way to design new alternative molecular and polymeric HTMs suitable for solution processed hybrid solar cells. Full article

Halide perovskite is one of the most promising semiconducting materials in a variety of fields such as solar cells, photodetectors, and light-emitting diodes. Lead halide perovskite single crystals featuring long diffusion length, high carrier mobility, large light absorption coefficient and low defect density, have been attracting increasing attention. Fundamental study of the intrinsic nature keeps revealing the superior optoelectrical properties of perovskite single crystals over their polycrystalline thin film counterparts, but to date, the device performance lags behind. The best power conversion efficiency (PCE) of single crystal-based solar cells is 21.9%, falling behind that of polycrystalline thin film solar cells (25.2%). The oversized thickness, defective surfaces, and difficulties in depositing functional layers, hinder the application of halide perovskite single crystals in optoelectronic devices. Efforts have been made to synthesize large-area single crystalline thin films directly on conductive substrates and apply defect engineering approaches to improve the surface properties. This review starts from a comprehensive introduction of the optoelectrical properties of perovskite single crystals. Then, the synthesis methods for high-quality bulk crystals and single-crystalline thin films are introduced and compared, followed by a systematic review of their optoelectronic applications including solar cells, photodetectors, and X-ray detectors. The challenges and strategical approaches for high-performance applications are summarized at the end with a brief outlook on future work. Full article
