All in all, the following main conclusions could be made from the conducted review of the literature. Nanoparticles in solar cells can effectively improve the performance of cells in PCE, but there must be certain stress on stability, toxicity, and low cost when choosing the right particle types.
Beyond such efforts for increasing the solar cells' efficiency and other physical features by nanotechnology measures, a significant portion of research works in this field have recently focused on enhancing the PVT systems' efficiency by nano techniques.
If doped with appropriate functionalization of CNTs, the film morphology is optimized. The most promising nanomaterial for a solar cell is perovskite and CNTs. Three main factors block PSCs' commercial application: PCE, cost, and stability. CNTs can be used as transparent and conducting materials instead of ITO.
Based on this, the possible future works could be: A combination of different nanoparticles in solar cells. Morphology engineering of nanoparticles such as the diameter and shape for applications in PVT systems.
The nanoparticles' mixture into the fluid changes the general properties (thermal conductivity, viscosity, and specific heat), and increases the thermal properties and thereby reducing the required heat transfer area throughout the panel's back.
