Special Issue Information
Aim and Scope: Metal halide perovskitehave been regarded as promising classes of materials for photovoltaics and optoelectronic devices, owing to the unique characteristics, such as long charge carrier diffusion lengths, precise tunable bandgaps, high light absorption coefficients, and high defect tolerance. Research on perovskite in the fields including photovoltaics, light-emitting diodes, lasers, X-ray imaging, and photodetectors has been gaining increasingly interest over the past years. Up to now, the efficiency of perovskite solar cells has grown from 3.8% in single-junction solar cells in 2009 to more than 25%, catching up the efficiency level of commercial silicon cells. Up to now, the key issues of perovskite photovoltaics and optoelectronic devices have become the stability, performance and large-scale production. This requires optimization of the film morphology, interface, device structure and the fabrication process. A lot work has been done on this issue and has made remarkable progress.
Subtopics: Perovskite solar cells, Perovskite light-emitting diodes, Perovskite lasers, Perovskite photodetectors, X-ray imaging based on perovskite.
Keywords: perovskite solar cells, optoelectronic devices, stability, performance, large-scale production.

Hybrid organic-inorganic lead halide perovskite solar cells have developed faster progress in the last decade. Nonetheless, organic-inorganic hybrid halide perovskites suffer from por stability, mainly due to the volatile nature of the organic components, whereas the presence of Pb entails toxicity and environmental problems. This paper reports a systematic study of suitable chemical-tuned perovskite semiconductor materials with enhanced stability and low toxicity as well by using accurate ab-initio methods. Thus, the thermodynamic stability as well as the most important mechanical properties will be assesed.

Efficiency potential of perovskite solar cells is discussed by considering non-radiative recombination loss based on external radiative efficiency (ERE), and resistance loss by using fill factor. The perovskite solar cells have an efficiency potential of 27.2% by improving ERE from around 1-3% to 30%. In order to industrialize perovskite solar cells, the development of high-efficiency large-area (more than 1 m2) modules with efficiencies of more than 15% is necessary. As one of the non-radiative recombination losses in perovskite solar cells, non-radiative recombination at grain boundary is analyzed. In addition, the efficiency potential of perovskite/Si tandem solar cells is also analyzed. The perovskite/Si 2-junction solar cells have an efficiency potential of about 36% by improving average ERE into 30% and by reducing resistance loss into 0.025.

Abstract: Perovskite solar cells in the n-i-p configuration use gold, produced by evaporation in vacuum, as the back-contact. To scale-up the production of perovskite solar cells, substituting gold with low-cost alternatives is desirable. So far in semi-transparent perovskite solar cells, stack of MoOx and Sn:In2O3 (ITO) has proven to be a viable alternative. However due to transparency of ITO a significant portion of light passes through the cell without being absorbed. To improve light absorption in the solar cell we propose and study the design rules for an array of Ag and Ag@SiO2 scattering particles as the rear-contact using coupled electrical and optical calculations. We found that the particle size is an essential parameter where meso-scale Ag and Ag@SiO2 scattering particles efficiently trap light in the cell due to their high scattering cross-section and low dissipation losses.
