Generally, first and second generations of photovoltaic (PV) cells are including mono‐crystalline silicon, amorphous silicon, and dye‐synthesized solar cells. Investigating the electrical current behavior of these sorts of PV cells shows that a modified multi‐ or single diode(s) model with shunt and series resistance can use as a good choice in a specific range of the current. For other constructions such as multi‐junction PV cells that consist of the third generation, the network models are the best choice. Also, the network models can be used for the first and second generations to improve the validity of model in the wider range of current. In addition to existing generations, PV array and modules, which are serial and parallel arrays of PV cells, will lead to a higher current or voltage. The main disadvantage of using these sorts of systems is their more space occupation. This problem can be solved by using the concentrated PV (CPV) systems that focus the received irradiation on a smaller surface. By considering the generated current, voltage, power, temperature effect, and financial analysis, it seems third‐generation PV systems are more efficient among all the generations. Finally, by considering the ratio of generated current on the occupied space, the CPV systems will be a better choice.

Hybrid photovoltaic thermal system is an effective method to convert solar energy into electrical and thermal energy. However, its effectiveness is widely affected due to the high temperature of photovoltaic panel, and it can be minimized by employing nanofluids to the PV/T systems. In this research, the effect of various nanoparticles on the PV/T systems was studied experimentally. The nanofluids Al 2 O 3 , CuO, and multiwall carbon nanotube (MWCNT) were dispersed with water at different volume fractions of 0, 0.5, 1, 2.5, and 5 (vol%) using ultrasonication process. The effect of nanomaterials on viscosity and density was classified. All tests were carried out in an outdoor laboratory setup for calibrating the PV temperatures, thermal conductivity, electrical power, electrical efficiency, and overall efficiency. In addition, the energy analyses were also made to estimate the loss of heat owing to the nanofluids. Results show that use of the nanofluid increased the electric power and electrical efficiency of PV/T compared with water. Furthermore, MWCNT and CuO reduced the cell temperature by 19%. Consequently, the nanofluids MWCNT, Al 2 O 3 , and CuO produced the impressive values of 60%, 55%, and 52% increase in an average electrical efficiency than conventional PV. Particularly, the MWCNT produced superior results compared with other materials. It is evidently clear from the result that the introduction of the nanofluid increases the thermal efficiency without adding any extra energy to the system. Moreover, insertion of Al 2 O 3 , CuO, and MWCNT on PV/T system increases the exergy efficiency more than conventional PV module.How to cite this article: Sangeetha M, Manigandan S, Chaichan MT, Kumar V.

Summary Innovative hybrid solar panels combining photovoltaic cells along with an efficient heat exchanger with attached fins to the parallel plates and water‐Al2O3 nanofluid as a working fluid is presented in this work. Twenty‐seven fins at the upper wall and 27 fins at the lower wall in labyrinth arrangement are used in simulations with fin lengths of 0, ¼, ½, and ¾ of the flow path height. Moreover, nanosolid particles dispersed in the base fluid range as 0 ≤ ϕ ≤ 0.2. In addition, Reynolds number Re at the inlet was varied such that 10 < Re < 80. Numerical finite element analysis using COMSOL software is utilized to investigate flow and thermal characteristics as well the overall efficiency of the hybrid system. Results show that as the Reynolds number, the length of the fin, and the volume fraction of the nanosolid particles increase, the overall efficiency increases. Moreover, increasing nanoparticle volume fraction and the fin length was found to increase the friction coefficient.
