“…To explain this experimental phenomenon, we developed a 3D model and analyzed the fundamental reason for the drop in Isc. However, further analysis showed that the V oc was a function of the I sc , as shown in (1), and that the FF variation was caused by the series resistance, which affected the I sc [13]. We calculated the variation in series resistance by means of fitting and presented the value of series resistance in Table 1.…”

“…Laser wireless power transmission (LWPT) has the outstanding advantages of high transmission power density, high immunity to electromagnetic interference, and good mobile flexibility, which is suitable for continuous power supply for mobile devices such as unmanned aerial vehicles, airships, and robots [1][2][3][4]. Unlike PV devices, which transform sunlight into electricity, laser photovoltaics convert monochromatic light into electrical power.…”

Laser wireless power transmission (LWPT) has various applications for mobile devices and specific equipment under extreme conditions. The light spot received by laser photovoltaics is usually non-uniform, resulting in system efficiency reduction. The output characteristics of 1 × 1 cm2 GaAs laser photovoltaics were measured under various illuminated areas. The experimental results showed that the efficiency decreased from 40.8% at the full irradiated area to 26.7% at 1/10 irradiated area. Furthermore, the drop in short-circuit current was the main factor for decreasing the efficiency. A three-dimensional (3D) finite element model was used to investigate this factor. The simulation results indicated that non-uniform irradiation could increase the total non-radiative recombination rate. The recombination rate of the absorption region increased from 6.0 × 1020 cm−3/s to 2.5 × 1021 cm−3/s, reducing the short-circuit current.

“…As an emerging transaction entity, distributed energy systems have difficulties in evaluation. Current research mainly focuses on new energy power stations, and there are few studies from independent power grid companies [3,4] . Guopeng Zhao et al [5] combined subjective and objective evaluation methods, and proposed a comprehensive evaluation method for AC/DC hybrid microgrid planning based on analytic hierarchy process and entropy weight method, and evaluated the problems by establishing a multi-attribute weighted decision model.…”

A comprehensive evaluation of the physical assets of power grid enterprises is conducive to promoting the management of assets of enterprises and avoiding the loss and waste of state-owned assets. This paper collects the objective statistics of the enterprise and the subjective scoring data of the experts in the index system for the past 5 years, and determines the comprehensive weight of each index through the combination of subjective and objective weights. Grey correlation and topsis method is used to establish a dynamic evaluation model for objective data to capture the trend of the comprehensive value of physical assets, and subjective data is used to establish a maturity model to calculate the maturity level of physical assets. In this way, the results of dynamic assessment and maturity assessment are combined to obtain the results of grid enterprise asset evaluation under multi-dimensional dynamic perspective. Finally, an empirical analysis using a grid data shows that the company should learn from the scientific management experience of 2016, maintain a high level of asset structure and utilization efficiency, and focus on improving the optimal management of asset decommissioning and health.
