This study aims to improve the efficiency of energy conversion, and optimize the design of the solar cell structure based on the single-stage solar photovoltaic grid-connected power generation technology. Firstly, the characteristics of conventional power batteries are analyzed. Additionally, the inverter structure analysis is the characteristic research method of the inverter system. The advantages and characteristics of the system are analyzed through the re-architecture of the photovoltaic grid-connected inverter system. In addition, the solar power generation cooling and heat dissipation technology are systematically re-optimized through experimental simulation. The results show that, compared with the traditional power battery, the solar photovoltaic gridconnected solar cell design is more stable in current and voltage. The energy conversion efficiency of the battery is increased by 23%, which can better realize the continuous and efficient use of solar energy. When the outer resistance region is infinite, the current of the battery rapidly rises to nearly 300A, while the voltage rapidly drops to 0V. Additionally, through the simulation experiment, the simulation cloud diagram and the temperature rise curve compare the thermal characteristic parameters of the traditional power battery and the solar battery under different charge and discharge rates. The life and safety of the power system are studied and the changes of the battery under high and low temperature conditions are analyzed. Battery life decay and thermal runaway are simulated. The results show that with the increase of charge-discharge rate and the increase of cycle times, the usable capacity of the battery will decrease seriously. When the battery is internally short-circuited, the local current inside the battery is too large and the battery thermal runaway occurs. The results have practical reference value for the optimal design of solar photovoltaic grid-connected systems and the efficient utilization of solar energy resources.

“…The efficiency of overall thermal energy utilization could be improved when the latent heat in the exhaust steam was used for the cogeneration of electricity and water. [ 209 ] Although using TES in CSP makes it stay competitive with PV, TES system is not favorable for many large‐scale application as it increases the capital cost and the additional equipment may complicate the entire system. Hence, recent efforts have also been made to directly couple the desalination plant to the renewable energy source without backup system.…”

With the change in climate patterns, rapid industrialization, and population growth, the increasing water and energy demand became a major concern in the past decades. Desalination has been touted as the answer to the global water crisis, due to its capability in producing high‐quality fresh water from saline water. The continual research and innovations in the desalination field have resulted in the commercialization of large‐scale desalination in many water scarce regions. In the energetic context, all desalination processes are energy intensive. With the necessity to make desalination a more affordable and sustainable process, the energy efficiency of desalination is becoming an important topic. Herein, it is aimed to provide insights into the recent efforts and strategies established to tackle the energy‐related issues of both, thermal‐based and membrane‐based desalination processes. Depending on the principle of various commercial and emerging desalination processes, the directions of energy efficiency improvements, which include operating condition optimization, high‐performance material development, and renewable energy exploitation are discussed. The ideas and strategies reviewed herein, whether in their implementation or theoretical stage, are expected to provide insights into the possible improvement for application in commercial desalination plants.

“…Hence, the planning of gas–electricity multi‐carrier system has attracted the most attention [149–151]. The planning studies on multi‐energy water–electricity systems can investigate the interactions between electricity supply, hydropower, water pumping and water desalination systems [152–154]. The interactions between cooling, heating and electricity systems are investigated in the thermal–electricity multi‐energy system [155, 156].…”
