“…The calculated energy of the optical band gap CuO in the case of direct transitions is in the range (1.45-1.60) eV (Figure 7b). These values are significantly higher than those given in the reference data for bulk CuO [18,24,42]. It is known that the change in Eg of the film material may be due to the presence of defects, small grain size, semiconductor degeneracy, etc.…”

Copper oxide thin films were obtained using pulsating spray pyrolysis method. The morphological, structural, and optical properties of fabricated films were studied. X-ray analysis revealed that the CuO thin films are single-phase. The study of films morphology by SEM and AFM methods showed that the obtained films have a fairly high surface roughness and contain grains of different shapes and sizes. It was found that the obtained films of copper oxide have high values of the absorption coefficient, which confirms the possibility of their use as absorbing layers for solar cells. The obtained values of the optical band gap of the material are in the range from 1.45 eV to 1.60 eV. Raman spectroscopy revealed three modes A1g, B1g, and B2g, of the crystal structure of monoclinic CuO. The devices based on p-type copper oxide are promising for solar cells fabrication because they can reduce production costs, due to their low cost and inexpensive production methods compared to silicon solar cells fabrication.

“…Compared with the single diode model, a double diode model is more accurate due to considering the influence of recombination current loss from the depletion region [41]. In the model, two diodes are introduced and they are parallel with both the shunt resistance and current source to shunt the photo-produced current source.…”

Estimating parameters for various photovoltaic (PV) models is of great importance in simulating, evaluating, and controlling PV systems. To achieve the effective and accurate parameters of PV models, this paper presents an improved brain storming optimization (IBSO). In IBSO, a new individuals' generation scheme is developed to balance the global and local search capability in the entire iterative process. Furthermore, an improved individual clustering scheme is developed to decrease the computational cost of K-means in the original BSO. In addition, a self-adaptive individuals' update scheme is introduced to further balance the global and local exploration capability. The proposed IBSO is employed to identify the parameters of different PV models, i.e., single diode, double diode, and PV module. The experimental results show that the IBSO can generate an extremely promising performance compared with other state-of-the-art algorithms, especially in terms of accuracy and reliability.

“…Cu 2 O is an attractive photosensitive material for photovoltaic and photo-electrochemical devices because of its nontoxicity, high absorption efficiency, and earth-abundance. , The theoretical power conversion efficiency (PCE) of Cu 2 O-based solar cells is predicted to be larger than 20% . However, until now, the reported experimental PCE value of Cu 2 O-based solar cells is still much lower than the theoretical value due to weak absorption property and serious interfacial recombination of prepared Cu 2 O. − Carrier-selective heterocontacts provide a negligible resistance to the collected carrier whilst simultaneously “blocking” the other carrier . The p-type Cu 2 O layer allows for high-efficient hole extraction and forms carrier-selective heterojunctions with an n-type semiconductor.…”

Cuprite, nominally cuprous oxide (Cu2O) but more correctly Cu2–x O, is widely used in optoelectronic applications because of its natural p-type, nontoxicity, and abundant availability. However, the photoresponsivity of Cu2O/Si photodetectors (PDs) has been limited by the lack of high-quality Cu2–x O films. Herein, we report a facile room-temperature solution method to prepare high-quality Cu2–x O films with controllable x value which were used as hole selective transport layers in crystalline n-type silicon-based heterojunction PDs. The detection performance of Cu2–x O/Si PDs exhibits a remarkable improvement via reducing the x value, resulting in the optimized PDs with high responsivity of 417 mA W–1 and fast response speed of 1.3 μs. Furthermore, the performance of the heterojunction PDs can be further improved by designing the pyramidal silicon structure, with enhanced responsivity of 600 mA W–1 and response speed of 600 ns. The superior photodetecting performance of Cu2–x O/n-Si heterojunctions is attributed to (i) the matched energy level band alignment, (ii) the low trap states in high-quality Cu2O thin films, and (iii) the excellent light trapping. We expect that the low-cost, highly efficient solution process would be of great convenience for large-scale fabrication of the Cu2–x O thin films and broaden the applications of Cu2–x O-based optoelectronic devices.
