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 transmittance of ∼83%–88%, with photovoltaic enhancement ∼4.0 × 103-folds compared to the intrinsic device [photovoltaic conversion efficiency (PCE) ∼1.22%], and it also demonstrates good stability over 5 months. This is mainly attributed BaTiZrSnHfCe HEO solid solution. In addition an appropriate Fermi level/high QY, HEO, carrier inducing/injecting/driving by synergism high entropy lattice distortion charge compensation, can improve kinetic equilibrium for achieving PCE-transparency while increasing holes via Cu vacancies/interstitial oxygen. Moreover, inorganic CuCrO2, WO3 maintain structural stability, indicating promising applications in optoelectronic devices.

Designing and synthesizing cost-effective catalysts that exhibit excellent performance of both the hydrogen evolution reaction (HER) oxygen (OER) is a formidable task in field electrocatalysis. Herein, we present Fe- P-codoped NiS amorphous film catalyst (FeNiSP) via meticulous control over cations anions metal compounds. The doped Fe P increases active sites, reduces charge transfer resistance, modulates electronic structures matrix. Leveraging these advantages, FeNiSP showcases exceptional bifunctional activities HER OER, with remarkably low overpotentials only 135 330 mV for achieving current density 100 mA·cm-2 during respectively. Additionally, cell voltage 1.56 V at 10 was achieved when it employed as anode cathode water splitting. Finally, function theory calculations further elucidate simultaneous presence leads to decrease band center S Ni. This consequential effect maintains balanced adsorption/desorption protons strengthened adsorption O-based intermediates on surface FeNiSP, subsequently contributing outstanding electrocatalytic OER activities.
