Abstract

A transparent pn junction comprising CuCrO2/Ba(Ti0.2Zr0.2Sn0.2Hf0.2Ce0.2)O3/WO3 was synthesized using a sol-gel-hydrothermal-annealing method. The CuCrO2/BaTiZrSnHfCe/WO3 achieves a transmittance of ∼83%–88%, with photovoltaic enhancement of ∼4.0 × 103-folds compared to the intrinsic device [photovoltaic conversion efficiency (PCE) of ∼1.22%], and it also demonstrates good stability over 5 months. This is mainly attributed to the BaTiZrSnHfCe HEO solid solution. In addition to an appropriate Fermi level/high QY, the BaTiZrSnHfCe HEO, with carrier inducing/injecting/driving by synergism of high entropy lattice distortion and charge compensation, can improve kinetic equilibrium for achieving PCE-transparency while increasing holes via Cu vacancies/interstitial oxygen. Moreover, inorganic CuCrO2, BaTiZrSnHfCe HEO, and WO3 maintain good structural stability, indicating promising applications for CuCrO2/BaTiZrSnHfCe/WO3 in optoelectronic devices.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
