“…Additionally, TiO 2 is another popular n-type material which is most commonly used as ETL. Despite having potential for excellent photovoltaic function, photo corrosion resistance, superior thermal stability, and the 3.2eV bandgap presents a difficulty [ 76 ]. PSC configurations with these materials and lead-based perovskite shows better characteristics that is clear from table, however due to their toxicity and instability problem further improvement are required through investigating new materials to replace these toxic and unstable materials.…”

“…Thus, optimizing growth condition was needed at each step of fabrication stages to obtain higher photocurrents. Although the conversion efficiency acquired is still low, it is the first efficiency obtained for this layer arrangement of n-TiO 2 /ZnO bilayer thin film as window layer with p-Cu 2 O as absorbing layer, as compared to single layering of TiO 2 or ZnO by using the same fabrication method [31,32]. The corresponding I-V measurement of n-TiO 2 /ZnO bilayer/p-Cu 2 O heterostructured thin film is shown in Figure 11.…”

Metal oxide semiconductor material has great potential to act as window layer in p–n heterojunction solar cell thin film owing to low production cost and significant properties in photovoltaic mechanism. In this work, n-TiO2/ZnO bilayer thin film was effectively constructed by means of sol-gel spin coating technique in an effort to diminish the electron-hole recombination rate from single-layered thin film. Annealing time is one of the important parameters in the fabrication process and was varied to study the impact of annealing treatment towards the thin film characteristics as window layer. It was found that the optimum parameter for the n-TiO2/ZnO bilayer was 500 °C with an annealing time of 2 h. High crystallinity of the n-(101)-TiO2/(002)-ZnO bilayer thin film was obtained, which consists of anatase and a hexagonal wurtzite structure, respectively. Orientation of (002)-ZnO is essential for deposition with the (111) Cu2O-absorbing layer due to a low different lattice mismatch between these two interfaces. The homogenous morphology of n-TiO2/ZnO bilayer was observed with a compact and dense layer. The improvement of transmittance has also been achieved in a range of 60%–80%, which indicated that the incident light can penetrate throughout the thin film directly. In addition, a p-Cu2O absorbing layer was successfully fabricated on top of n-TiO2/ZnO bilayer thin film to form a p-n junction in order to visualize significant electrical rectification properties. The existence of p-Cu2O was confirmed by a (111)-peak orientation and triangular shape in structural and morphological properties, respectively.

“…LED is so-called the fourth-generation lighting source or green light source, with no warm-up time, fast response time, a small size, low power loss, low environmental pollution, high reliability and other advantages. [10][11][12][13] Although it it is easily made into minimal or series of devices for various applications such as automobiles, computers, traffic lights, the communication industry, backlighting of LCD panels, LED screens, etc. [14][15][16] Moreover, high-power LED lights also give rise to a huge heating problem.…”

This project reports on improving the thermal performance of light-emitting diode (LED) packages based on an optimized thermal structure with a sprayed cuprous oxide coating. Eighteen orthogonal arrays of LED aluminum plates were used and the influence of the parameters of thermal dissipation structure on the LED junction temperature was established. The junction temperature of the LED assembly is developed by various heat dissipation structures based on Taguchi methods. The experimental results show that by measuring the temperature of the 12W LED module, the best results were compared with the lowest values in the overall experiment, where the junction temperature dropped from 67°C to 51°C Also, the contribution of the error to the total variance is about 0.8%, indicating that the experiment is quite successful and robust results. It was found that lower junction temperature values were obtained with optimized heat sink structures with Cu2O-coated Al substrates, and the thermal performance of the LEDs was further improved.
