There are two primary illnesses that afflict the elderly worldwide those are Retinitis Pigmentosa (RP) and Age-related Macula Degeneration (AMD). Presently there has been a large research focus to develop treatment methods that would cure AMD induced vision disability and RP diseases. Silicon Micro Photo Diode Array, ARGUS II, and ALPHA IMS are a few of the latest therapeutic approaches suggested for curing these diseases (MPDA). These systems have led to many undesirable side effects in patients. The objective of this research work is to create an affordable device that improves the vision recovery. Photovoltaic cells composed of nanomaterials such as carbon nanotubes and graphene are known as Nano Photo Diode Arrays (NPDA). Under incident light, they may generate stimulating electrical pulses to restore vision, photoreceptor cells are stimulated in the retina. The authors of this study sought to optimise the several geometries of Graphene/SWCNT-C60/Al bilayer hetero junction photodiodes that would constitute the NPDA for subretinal implantation.
