Fiber-Shaped Polymer Solar Cell | SpringerLink

A semiconducting polymer can be excited provided that incident photons have energy higher than the bandgap. On account of the large bandgap of semiconducting polymer (~2 eV), which corresponds to a small range of spectrum available, narrowing the bandgap is a powerful strategy to enhance the utilization of solar energy (Fig. 4.1b).

6 FAQs about [Fiber network for solar cells]

What are fiber-shaped solar cells?

Fiber-shaped solar cells are a type of low cost and flexible photoelectrodes fabricated using materials such as metal, optical fiber, and conductive fiber. They broke the limitations of traditional flexible solar cells in terms of shapes and materials.

Are fiber-shaped organic solar cells a good choice for wearable electronics?

Due to the unique advantages of the fiber-shaped organic solar cells (FOSCs), such as all-solid-state, ease of fabrication, and environmental friendliness, FOSCs are the strongest candidate among all types of FSCs for wearable electronics. However, the development of FOSCs is seriously lagging behind other types of FSCs.

How is the quantum efficiency of fiber-shaped solar cells determined?

The external quantum efficiency of the fiber-shaped solar cells was determined in the air by a fully integrated EQE characterization system (Newport, Quantx-300). The ideality factor (n) is derived from the slope of the dark I – V curve, and the basic cell equation in the dark is:

What are the requirements for flexible solar cells?

For flexible solar cells, both their active layers (such as silicon-based solar cells and compound semiconductor-based solar cells) and their substrates should meet the flexible requirement. The flexibility of the substrate is directly and closely related to their power conversion efficiency, stability, and cost.

Are polymer-based solar cells flexible?

Polymer-based solar cells are widely studied as the most potential flexible solar cells because polymer materials have the highest flexibility, film forming ability, and mechanical toughness compared with those of other material systems. There are two types of polymer solar cells: the standard type and inverted type.

Can a polymer fiber rigid network improve thermal stability?

Herein, a unique approach is presented, based on constructing a polymer fiber rigid network with a high glass transition temperature (Tg) to impede the movement of acceptor and donor molecules, to immobilize the active layer morphology, and thereby to improve thermal stability.
