# Organic Nanostructured Materials for Sustainable Application in Next Generation Solar Cells
###### Abstract
Organic-inorganic hybrid solar cells (Figure 2) have arisen amongst the most promising light absorber layers essential for next-generation solar cells. They are multi-component molecules with at least one organic (typically the polymer) or inorganic material in the nanometre scale size domain, and they usually have substantially better performance than their non-hybrid counterparts. However, organic cations' thermal and moisture sensitivity in the hybrid remains the major source of device instability [17]. The lateral charge transfer between the organic and inorganic layers is highly curtailed in a hybrid, but the active perpendicular layer orientation is thought to enable charge passage along the inorganic sheets to the substrates, as illustrated in Figure 2[18]. Based on various favorable properties, organic solar devices have the capacity to overcome the difficulties faced by silicon-based and organic-inorganic hybrid solar cells [19]. The purpose of this review is to highlight

Organic semiconductor materials primarily consist of conjugated small molecules and polymers. Organic photovoltaic devices based on semiconducting conjugated polymers have emerged as a viable alternative to traditional solid-state (silicon-based) solar systems, primarily due to their affordable production costs [20] for soluble organic molecules (produced via roll-to-roll processing techniques), abundant material (decreasing the supply and price constraints) as well as flexible substrates (permitting a wide variety of uses) [21]. They cleared the path for [PERSON] to claim in 1986 that he had developed the first thin-film OSC that exceeded 1% efficiency. Despite the fact that they attracted a lot of interest for their ability to generate energy effectively even under dispersed light or interior illumination, solid-state dye-sensitized photovoltaic cells (DSSCs) still have low power conversion efficiency (11%) which still has to be improved [15]. Moreover, the light electrolyte causes a safety issue since the iodine and organic solvents can be volatized and leak; affecting the cell's longevity [22]. The all-solid perovskite solar cell, which is based on DSSC but overcomes DSSC's limitations, received a lot of interest from scientists as soon as it was disclosed. Despite the fact that the photoelectric conversion efficiency (PCE) of PSC has rapidly increased from 3.8 to 23.3% [23], device stability remains a challenge that has limited their applications. In general, each component of the technology has an impact on its performance by completing its assigned responsibilities. As a result, optimizing the device components is critical. As a result, OPVs provide an alternate solution to the problems that traditional cells confront, owing to their structural flexibility, ease of device manufacture, and quick energy recovery.
