     In this paper, the performance of a silicon cell with a Fresnel lens (FL) for building a solar photovoltaic concentrator system was evaluated; the solar concentrator is a Fresnel lens, which is a point concentrator made of  polymethyl-methacrylate (PMMA) as a thin lens for the optics system. As the radiation from the sun on the solar cell is concentrated to the levels of solar radiation  of 750, 1300, 1930, 2600, 4250, 7250, and 10500) W/m2, the work was conducted at the midday in summer weather conditions, with ambient temperatures ranging 40-45 °C. The evaluation was performed in three cases; each case was conducted in succession. The performance of the cell was evaluated first without a cooling system, and then it was evaluated using the heat-sink (phenolic (pcb) printed circuit boards type). Finally, the fan with the heat-sink was used as a cooling system, which was more effective in dissipating the heat generated in the solar cell. The evaluation,  based on the current and voltage (I-V) results with cell temperature, showed the following efficiency values for the abovementioned  three cases, respectively:(6.91 ,7.76 ,6.65 ,7.77 ,6.27 ,4.74 ,3.37 ) %, (7.41 , 9.21 , 7.5 , 8.31 , 9.71 ,7.53 ,4.72 ) %, and (7.63 ,9.34 , 7.57, 8.37 , 10.2 ,7.75, 4.7) %.

Phase change material (PCM) based passive cooling of photovoltaics (PV) can be highly productive due to high latent heat capacity. However, the low rate of heat transfer limits its usefulness. Thus, the presented work aims at the improvement in PV cooling by using finned PCM (FPCM) heat sinks. In the present study, PCM heat sink and FPCM heat sinks were investigated numerically for PV cooling and the extracted heat is used for space heating. 4 kWp PV, PV-PCM and PV-FPCM systems were studied under the weather conditions of Southeast of England. It was observed that the PCM heat sinks can drop the peak PV temperature by 13 K, whereas FPCM heat sinks can enhance the PV cooling by 19 K. The PCM heat sinks can increase the PV electrical efficiency from 13% to 14%. Moreover, the daily electricity generation can be boosted by 7% using PCM and 8% by using FPCM heat sinks. In addition, 7 kWh of thermal output was achieved using the FPCM heat sink, and the overall efficiency of system increased from 13% to 19%.

Solar Cell Performance

The present work aims at decrease the cost of the photovoltaic (PV) solar system by decreasing the area of expensive solar cells by low cost optical concentrators that give the same output power. Output power of two types’ monocrystalline and polycrystalline silicon solar cells has been measured with and without presence of linear focus Fresnel lenses (FL) with different concentration ratios. Cooling system has been used to decrease the effect of temperature on solar cell performance. The results indicated that the increase in the output power is about 5.3 times by using Fresnel lens concentrator without using cooling system in comparison with solar cell without concentrator, while it is about 14.6 times by using cooling system. The efficiency of monocrystalline solar cell without cooling system is about 11.2% for solar irradiance 0.698 kW/m2, this value decrease to 3.3% for solar irradiance 12.4 kW/m2 and concentration ratio 17.7 by using Fresnel lens concentrator, while when using cooling system the efficiency enhance to 12.9% and 8.8% for solar irradiance 0.698 and 12.4, respectively.

Passive Cooling System

High energy demand is leading to the replacement of fossil energy with renewable sources such as solar energy. Solar cells are devices used to generate solar energy. However, when exposed to sunlight with high intensity, a solar cell can suffer a decrease in performance due to overheating. This issue can be addressing by adding a cooling system. This study used a passive cooling system by adding a heat sink with fins to the body panel of the solar cell. The advantage of the passive cooling system is that it does not require additional energy. The number of fins and types of material were varied to obtain the best passive cooling system. The number of fins used was 5, 10, and 15, and the materials used were aluminum and copper. The wind speed vector and the temperature distribution were investigated through simulation. The results showed an increase in the number of fins provided better cooling capacity and increased the photovoltaic performance. The best cooling capability and performance were obtained using 15 fins with a copper base and fin heat sink materials. The decrease in temperature and the increase in efficiency were 10.2 °C and 2.74%, respectively. Therefore, the use of passive cooling system based on heat sinks with fins could provide a potential solution to increase performance and prevent overheating of photovoltaic (PV) panel systems.

Thermal Calculations

In the modern world, both developers and engineers are more and more carefully approaching the study and calculation of the thermal conditions of electronic devices. This is a necessary measure, due to the tendency to increase the density of the arrangement of electronic radio products (ERI) on printed circuit boards (PCBs), to reduce sizes while increasing power, and also to increase the overall complexity of electronic devices. The use of local topological heat sink solutions (heat sink holes) allows you to reduce the temperature conditions of the ERI, but requires the use of a detailed mathematical model of the PCB in thermal calculations. The article discusses the use of such a model and its comparison withthe traditional approach

Body mounted germanium substrate solar cell arrays form the faces of many small satellite designs to provide the primary power source on orbit. High efficiency solar cells are made affordable for University scale satellite programs as triangular devices trimmed from wafer scale solar cells. The smaller cells allow the array designs to pack tightly around antenna mounts and payload instruments, giving the board design more flexibility. We are investigating the reliability of solar cells attached to FR-4 and carbon core laminate printed circuit boards. FR-4 circuit boards have significantly higher thermal expansion coefficients and lower thermal conductivities than germanium. This thermal expansion coefficient mismatch between the FR-4 board and the components used cause major concern for the power system when considering a failure of the solar cells, such as a series of cracked cells or faulty solder joints. These failures are most likely to happen with a longer orbital lifetime and longer exposure to the harsh environment the satellite will experience while in orbit. Carbon core laminates provide an advanced alternative because the core thickness can be selected to more closely match the device substrate, or at least provide a wider thermal expansion coefficient range to match the components on the board. We are also comparing various methods of attaching the solar cells to the printed circuit boards, using solder paste alone and in parallel with a silicone adhesive, considering the application of these adhesives by comparing the solder joints under x-ray when applied by screen printing versus stencil printing, and looking closely at the cleaning processes for array assembly. Storage, vacuum exposure, thermal cycling, functional and vibration testing will be used to compare the survivability and performance of the solar arrays.
