Among many available photovoltaic technologies at present, gallium arsenide (GaAs) is one of the recognized leaders for performance and reliability; however, it is still a great challenge to achieve cost-effective GaAs solar cells for smart systems such as transparent and flexible photovoltaics. In this study, highly crystalline long GaAs nanowires (NWs) with minimal crystal defects are synthesized economically by chemical vapor deposition and configured into novel Schottky photovoltaic structures by simply using asymmetric Au-Al contacts. Without any doping profiles such as p-n junction and complicated coaxial junction structures, the single NW Schottky device shows a record high apparent energy conversion efficiency of 16% under air mass 1.5 global illumination by normalizing to the projection area of the NW. The corresponding photovoltaic output can be further enhanced by connecting individual cells in series and in parallel as well as by fabricating NW array solar cells via contact printing showing an overall efficiency of 1.6%. Importantly, these Schottky cells can be easily integrated on the glass and plastic substrates for transparent and flexible photovoltaics, which explicitly demonstrate the outstanding versatility and promising perspective of these GaAs NW Schottky photovoltaics for next-generation smart solar energy harvesting devices.

“…In the past decades, lots of attempts have been made to achieve transparent and highly conducting metal film structures [1][2][3][4]. A typical approach is to introduce holes or slits in the metal films to obtain enhanced optical transmission [5,6]. Unfortunately, these hollowed metallic film structures are with some drawbacks including the limited light transmittance and weakened electrical conduction, which are needed to be overcome before their use in actual applications.…”

“…Concept Figure 1 shows the proposed structure of LAD. Among the many display devices, it is thought that the organic light-emitting diode with color reflection [3,4] (colored OLED) is the most effective device for simultaneously performing the reflective and emissive modes. A guesthost liquid-crystal device [5] (GH-LC) was selected by means of light shutter (LS) because it can realize the black color without a polarizer, and can thus provide the advantages of low power consumption and high image quality.…”

In this paper, a new light-adaptable display (LAD) structure with minimum power consumption is proposed for the future advertising service, and the demonstrated results are reported. An organic light-emitting diode with color reflection (colored OLED) was applied for the reflective-and emissivemode device, and a guest-host liquid-crystal device (GH-LC) was adopted for the light shutter device. The current efficiency and reflectance of the colored OLED were 35.15 cd/A at 457 cd/m 2 luminance and 63% for the yellow color, respectively. The measured contrast ratio of GH-LC was 15.5:1 at darkroom conditions, respectively. Transparent oxide thin-film transistors were used for the backplane, and their average mobility was 9.08 cm 2 /V s, with a 0.5 standard deviation. Through the optimization of the fabrication process and the structures of each device, the LAD adaptively operating according to the environmental illuminance from dark to 10,000 nits was successfully demonstrated. Moreover, a new LAD driving method was proposed for minimizing the power consumption. ARTICLE HISTORY
