Special Issue Information

Dear Colleagues,

As the 4th industrial revolution and the IoT era approaches, interest in optoelectronic devices is rapidly increasing. Optoelectronics, characterized by being thin, light, flexible, and stretchable, can be applied to solar cells, displays, and sensors using polymer, organic, and quantum-dot materials. Therefore, this Special Issue will cover research papers on optoelectronic devices using polymers and the following topics:

  1. Solar cell devices using polymer material (for example, organic solar cell, polymer solar cell, quantum dot solar cell, and perovskite solar cell);
  2. Light-emitting devices using polymer material (for example, organic light-emitting diodes, quantum-dot light-emitting diodes, and light-emitting electrochemical cells);
  3. Solution process for optoelectronic devices (for example, inkjet printing process and spin coating process).

Abstract
Organic/silicon hybrid structures have been extensively studied for the application of solar cells due to their high photoelectric conversion efficiency and simple fabrication process. However, studies of lateral photovoltaic effects (LPEs) in the devices are still scarce. Herein, the Si/SiO2/PEDOT:PSS devices [...] Read more.
Organic/silicon hybrid structures have been extensively studied for the application of solar cells due to their high photoelectric conversion efficiency and simple fabrication process. However, studies of lateral photovoltaic effects (LPEs) in the devices are still scarce. Herein, the Si/SiO2/PEDOT:PSS devices were prepared by spin-coating, and showing the lateral photovoltage (LPV) sensitivity of 14.0 mV/mm at room temperature, which is higher than the control samples of Si/SiO2 (0.1 mV/mm) and Si/PEDOT:PSS (9.0 mV/mm) structures. With the decrease in temperature, the lateral photovoltage increases initially, and reaches a peak at around 210 K, then drops accordingly. The enhancement of LPE can be mainly ascribed to the formation of the p-n junction and the native oxide layer at the organic/inorganic interface. Full article

Organic solar cells (OSCs) are promising renewable energy sources for replacing fossil fuels. The power conversion efficiency (PCE) of OSCs has increased based on tremendous effort in material and device engineering. Still, the stability of OSC, such as long lifetime, negative temperature coefficient, must be enhanced for commercialization. In this study, we investigated OSC performance at a high operating temperature near 300–420 K, which are typical temperature regions in photovoltaic applications, with a different hole-extraction layer (HEL). The metal oxide-based HEL, MoO3, exhibited stable operating properties with a PCE drop rate of −0.13%/°C, as compared to polymeric HEL, PEDOT:PSS (−0.20%/°C). This performance reduction of polymeric HEL originated from the degradation of the interface in contact with PEDOT:PSS, as compared to the robust inorganic metal oxide HEL. Full article
