Special Issue Information

Dear Colleagues,

Solar cell technologies have gained extensive attraction owing to their potential to meet the global energy demand in a sustainable manner. A great deal of research efforts have been employed to enhance the efficiency of conventional and recently developed photovoltaic (PV) materials while hunting for candidates to increase the solar conversion efficiency. Additionally, device architecture also plays a crucial role in realizing the high power conversion efficiency of solar cells. Technological development in recent research can be classified according to different generations of solar cells. Among other things, the first two-generation solar cell covers the relationship between generation and the current market. Moderate market yields are achieved by medium- and low-cost technologies for first-generation cells (mono or polycrystalline silicon cells). Thin-film technologies, or second-generation, cells are based on more effective but less expensive manufacturing techniques. Third-generation cells showcase numerous innovative designs and new materials that all utilize the priciest yet most effective solar cells. Fourth-generation cells include hybrid materials that are currently being investigated. These materials include more stable, novel inorganic nano-structures like metal oxides and nanomaterials, as well as flexible, economical polymer films. It is indispensable to explore the different aspects of solar cell technology regarding materials, efficiency, and fabrication costs. In fourth-generation solar cells, special attention is being given to the different roles of organic and hybrid components. Furthermore, the stability of fourth-generation solar devices is also a major point of attention. Therefore, recent research has revealed that besides efficient materials, innovative device configuration is important for the practical application of solar cells. Meanwhile, advanced characterization instruments capable of investigating material properties are also being developed, enabling researchers to fundamentally understand several aspects of material properties. This has given scientists a variety of techniques to simultaneously engineer a material’s structural, morphological, electrical, chemical, and optical properties in order to enhance the device’s performance.

High temperatures in photovoltaic (PV) modules lead to the degradation of electrical efficiency. To address the challenge of reducing the temperature of photovoltaic modules and enhancing their electrical power output efficiency, a simple but efficient photovoltaic cooling system based on heat pipes (PV-HP) is introduced in this study. Through experimental and numerical investigations, this study delves into the temperature characteristics and power output performance of the PV-HP system. Orthogonal tests are conducted to discern the influence of different factors on the PV-HP system. The experimental findings indicate that the performance of the PV-HP system is superior to that of the single system without heat pipes. The numerical simulation shows the effects of system structural parameters (number of heat pipes, angle of heat pipe condensation section) on system temperature and power output performance. The numerical simulation results show that increasing the angle of the heat pipe condensation section and the number of heat pipes leads to a significant drop in system temperature and an increase in the efficiency of the photovoltaic cells.
