Solar cells of this kind, characterized by reduced material usage, lower manufacturing costs, and flexibility, typically achieve conversion efficiencies ranging from 6% to 15% (Jaiswal et al., 2022).
Power conversion efficiency: the cell efficiency of OPVs is far below that of traditional silicon cells. Silicon cells will typically reach an efficiency of between 20% – 25%. Meanwhile, organic solar cells can currently only reach between 8%-12%. Lifespan: the lifespan of organic solar cells is far less compared to traditional solar cells.
The lightweight, flexible, and thinly filmed, plastic solar cell is far more durable and able to cover a much larger area than traditional solar cells. The drawbacks of organic solar cells are the efficiency and lifespan problems compared to traditional solar cells.
Efficiency losses in the solar cell result from parasitic absorption, in which absorbed light does not help produce charge carriers. Addressing and reducing parasitic absorption is necessary to increase the overall efficiency and performance of solar cells (Werner et al., 2016a).
Throughout the years, the evolution of solar cells has marked numerous significant milestones, reflecting an unwavering commitment to enhancing efficiency and affordability. It began in the early days with the introduction of crystalline silicon cells and progressed to thin-film technology.
Solar panels are generally considered reliable and durable, with an average lifespan of 25 to 30 years. The panels are designed to withstand various environmental conditions, including heat, cold, wind, and rain, and are often tested for durability and efficiency under extreme conditions.
Organic solar cells are a polymer cell made from carbon-based materials and organic electronics. The lightweight, flexible, and thinly filmed, plastic solar cell is far more durable and able to cover a much larger area than traditional solar cells.
