“…However, it was soon realized that this blend has reached its maximum PCE limit of around 5% where it could not go beyond this value. This restriction is due to the high-lying HOMO of P3HT (4.9 eV) [30], which gives a maximum V OC of only around 0.6 V. Hence, many researchers begin to search for new methods to increase V OC through material engineering.…”

Organic solar cells (OSCs) have been gaining great popularity in recent years due to their potentials to be low cost, lightweight, and flexible. The performance of OSCs is growing steadily, and they have achieved a power conversion efficiency close to 10% (for single-junction polymer-fullerene OSC). Although there are still limitations and challenges faced by the development of OSCs, in view of the potentials, recent studies have been focusing on the design optimization of OSC layer structure through material engineering, interfacial layer insertion, layer thickness optimization, and morphological control. In this paper, we provide a comprehensive review and detailed discussion on the optimization works and development on OSCs, with particular focus on the bulk-heterojunction (BHJ) polymer-fullerene OSCs. We also provide a summary of the performance, in a chronological order, and the future outlook of OSC.

“…On this account, donor polymer with a lower HOMO promises a higher V OC . For example, P3HT has a HOMO of~4.9 eV, rendering a V OC of 0.6 V [27]. Chemical modification, like introducing fluorene moieties to polymer, can shift the energy level of the donor and increase the open-circuit voltage [28].…”

Currently, fiber-shaped solar cells are materialized in two types of solar cells, the polymer solar cell (PSC) and the dye-sensitized solar cell (DSC), whose structures are technically feasible for transforming into one-dimensional configuration. In this chapter, we discuss the polymer solar cell first including its developing history and working mechanisms. It is widely acknowledged that the electrode plays a pivotal role in the performance of solar cells. On this account, we proceed from remolding different materials into fiber shape as electrodes and shed light on their impact on flexibility, stability, and power conversion efficiency (PCE) of the polymer solar cell. Moreover, we present our attempts towards application pertaining to wearable devices. Specifically, we fabricated the stretchable polymer solar cells and integrated the solar cell with supercapacitors, which is discussed in detail in this chapter.

“…The metal-free organic dyes as sensitizers such as borondipyrromethene (BODIPY) dyes [5], indoline dyes (D102 and D149) [6], infrared absorbing thiapenta-carbocyanine dye [7] and so forth, have been intensively studied. Improvement of absorption of the solar spectrum has been investigated mainly by adding different types of dopants such as transition metal elements, nonmetal elements, nitrogen, sulfur, boron, carbon nanotubes, and so forth [8][9][10][11][12][13][14][15][16].…”

Geometries, electronic properties, and absorption spectra of the dyes which are a combination of thiophene based dye (THPD) and IR dyes (covering IR region; TIRBD1-TIRBD3) were performed using density functional theory (DFT) and time dependent density functional theory (TD-DFT), respectively. Different electron donating groups, electron withdrawing groups, and IR dyes have been substituted on THPD to enhance the efficiency. The bond lengths of new designed dyes are almost the same. The lowest unoccupied molecular orbital energies of designed dyes are above the conduction band of TiO2and the highest occupied molecular orbital energies are below the redox couple revealing that TIRBD1-TIRBD3 would be better sensitizers for dye-sensitized solar cells. The broad spectra and low energy gap also showed that designed materials would be efficient sensitizers.
