Special Issue Information

Dear Colleagues,

The supply of clean energy at low cost is one of the great challenges of the future. Solar cells, which convert solar energy into electric energy, are the most likely clean energy source. The production of solar cells has increased year by year; however, the production cost of solar cell should be further reduced to compete with thermal power generation that uses fossil fuels.

Until now, many kinds of solar cells have been investigated, using crystal silicon, amorphous silicon, GaAs, CuInSe, Cu2ZnSnS4, CdTe, TiO2, ZnO, perovskite material, organic material, etc. In order to drastically increase the power conversion efficiency, the use of nanostructure and/or nanomaterials will be the most effective.

The aim of this Special Issue is to attract leading researchers in the area of nanostructure or nanomaterials for the improvement of solar cells using inorganic or organic or organic/inorganic hybrid materials. Accepted contributions will cover not only the fabrication of solar cells but also the characterization of nanomaterials or nanostructures, device simulation, etc.

Bismuth oxyiodide (BiOI) is expected to be promising material for photovoltaic devices since it has good activity under the visible range. Here, we studied the annealing treatment on BiOI and its effect on the photovoltaic application. Firstly, the synthesized BiOI from Bi(NO3)3 and KI was annealed at varied temperatures (100–550 °C). The structural investigation by X-ray diffraction and Raman spectroscopy analysis was supported with morphology and optical analysis by scanning electron microscope (SEM) and UV-Visible spectroscopy. Due to the heating treatment, it could result in iodine-deficient bismuth-based materials, namely Bi7O9I3, Bi5O7I, and β-Bi2O3. Secondly, the photovoltaic test measurement was performed by solar simulator air mass (AM) 1.5 illumination which presented the current-voltage curve from each material. The enhancement of photovoltaic performance was given by the increase of temperature up to 300 °C. At that temperature, the performance of the device which consisted of Bi7O9I3 achieved three times higher efficiency than the annealed parent BiOI at 100 °C. Hence, the structural changing owing to the oxygen addition to BiOI structure had an impact on the photoelectrochemical cell. Based on this work, it is possible to attempt BiOI derivation with suitable holes and electron transport layers for better photovoltaic performance. Full article

From a niche field over 30 years ago, quantum dots (QDs) have developed into viable materials for many commercial optoelectronic devices. We discuss the advancements in Pb-based QD solar cells (QDSCs) from a viewpoint of the pathways an excited state can take when relaxing back to the ground state. Systematically understanding the fundamental processes occurring in QDs has led to improvements in solar cell efficiency from ~3% to over 13% in 8 years. We compile data from ~200 articles reporting functioning QDSCs to give an overview of the current limitations in the technology. We find that the open circuit voltage limits the device efficiency and propose some strategies for overcoming this limitation. Full article
