The term organic solar cells are used for materials in which the light-harvesting layer or materials is made up of a polymer. The organic solar cells had the advantage of easiness in the fabrication and lightweight nature. But they were far behind the monocrystalline solar cells, because of their low efficiency. Conjugated polymers with ability to be doped and conducting polymers are employed in the organic solar cells.
Electrochemistry of Porous Polymers and Hybrid Materials
Published in Antonio Doménech-Carbó, Electrochemistry of Porous Materials, 2021
Organic solar cells are devices that employ organic molecules as light absorbers to generate electron-hole separation to cause a potential difference. This is a particular class of photovoltaic cells (typically constituted by semiconducting materials) where the light absorber is a small molecule or a conducting polymer [36].
Exotic Solar Technologies
Published in Anco S. Blazev, Solar Technologies for the 21st Century, 2021
The performance of organic solar cells has recently been greatly improved, opening the path towards an alternative renewable energy source. To realize the main advantages of these cells, low cost and flexible devices, the development of electrodes is of great importance. The high cost, brittleness, and high temperature processing of indium tin oxide (ITO), commonly used in photovoltaic applications, drive a search for alternative electrode technologies.

There are several kinds of thin film solar cells which are suitable for airship applications. Confirmed efficiency records of such types of solar cells are 11.7% for organic solar cells on a submodule (see Distler, Brabec, and Egelhaaf 2020), 22.6% for Perovskite on a cell (see Peng et al. 2021), and 10.2% for amorphous Silicon on a cell (see Matsui et al. 2015). These types of solar cells are potential candidates for future airship application, since they can be produced on lightweight and flexible substrates. The weight of these solar cells is about 100 g/mm2 (see Zeppelin 1908). In this work, data of Copper Indium Gallium Selenide (CIGS) thin film solar cells are selected, since they are commercially available and have optimal properties for a potential use on airships. In particular, they are flexible, lightweight, and highly efficient. For larger airships, a high efficiency of the solar cells is an important requirement, due to the relatively small ratio of the surface’s area to the airship’s volume comparing to the one of smaller airships. Whereas for smaller airships, a low weight of the solar cells is the most important requirement.

Renewable resources, such as organic solar cells, have attracted a lot of attention of researchers [1]. These resources are entirely free from pollution and are a key issue for future industries [2]. Due to the low cost and simple manufacturing process, organic solar cells offer a potential opportunity to create a very widespread solar source of energy. In the last years, the use of organic solar cells in various industries and structures, such as aerospace, electronics, and automotive, has gained growing popularity [3]. The mentioned structure can be used as the main part of complex systems such as Refs. [4–7]. Many researchers [8–17] presented some studies on the stability and instability laminated composite complex structures under different conditions by generalized differential quadrature method, discrete singular convolution method, meshfree method, Navier method, etc. They used various size-dependent theories to investigate the nonlocal dynamic responses of the instability laminated composite complex structures. Also, the dynamic stability analysis of the multilayer organic and artificial shell, panel, beam, and disk was reported in several papers [18–23] based on mathematical modeling, experimental framework, and computer simulation. Their results showed that the number of layers in the laminated strictures and applied mechanical load make a remarkable change in the frequency of the organic and artificial structures. In addition, low- and high-velocity impact responses of the laminated composite attracted the attention of the researchers [24–34] for improving the performance of the applicable laminated composite complex structures. They found that each structure could experience different responses due to a low value of the external electromechanical load.

At present, the efficiency of energy conversion of organic solar cells has approached 5%, with the highest values being given for donor–acceptor cells made of various organic materials and hybrid combinations of organic materials with nonorganic. Different concepts of obtaining p–n junctions concern not only in the type of materials used (mainly CuPc, ZnPc, PTCDA, PTCBI, PCBM) but also in the technology of their processing (vacuum coating, spin coating, zone coating).[141516]
