Major Impediment

Organic–inorganic hybrid perovskite solar cells (PSCs) have made immense progress in recent years, owing to outstanding optoelectronic properties of perovskite materials, such as high extinction coefficient, carrier mobility, and low exciton binding energy. Since the first appearance in 2009, the efficiency of PSCs has reached 23.3%. This has made them the most promising rival to silicon-based solar cells. However, there are still several issues to resolve to promote PSCs’ outdoor applications. In this review, three crucial aspects of PSCs, including high efficiency, environmental stability, and low-cost of PSCs, are described in detail. Recent in-depth studies on different aspects are also discussed for better understanding of these issues and possible solutions.

Solar Cell Technology

Perovskites are increasingly proved to be a promising candidate for making absorber materials for high-efficiency and low-cost next-generation solar cells. There are several models proposed for perovskite solar cells similar to the conventional solar cells; their operation also has specific characteristics and requires the development of a more general physical model to study, thus optimizing the cells and improving the performance of the panels. This paper develops such a physics-based intuitive model to consider the performance of two high-efficiency types of perovskite solar cells, taking into account heterogeneous properties, with filtered transport layers, recombination, charge selection, and voltage-dependent collector. This model would allow experimentally to estimate critical parameters of perovskite solar cells, understand the performance bottleneck, and predict the performance of perovskite solar cells and suggest further study for perovskite solar cell technology development.

Nano Antennas

The solar energy is able to supply humanity energy for almost another 1 billion years. Optical nano-antennas (ONAs) are an attractive technology for high efficiency, and low-cost solar cells. These devices can be classified to semiconductor nano-wires and metallic nano-antenna. Extensive studies have been carried out on ONAs to investigate their ability to harvest solar energy. Inspired by these studies, the scope of the chapter is to highlight the latest designs of the two main types of ONAs. The metallic nano-antennas are discussed based on the following points: plasmon, modeling, and performance of antenna designs using different configurations and materials. Moreover, the semiconductor nano-wires are studied thoroughly in terms of photonic crystals, antenna design with different patterns, nano-wire forms and materials. Also, the applications of ONAs and their fabrication aspects such as diode challenges are presented in detail. Finally, three novel designs of ONAs are presented and numerically simulated to maximize the harvesting efficiency.
