Currently, the world is facing an energy crisis. One of the techniques to fulfill the energy demand is to increase the utilization of solar energy. For harvesting solar energy in large amounts, it is essential to develop efficient solar cells. Notably, solar cells (photovoltaic cells) produce electricity from solar energy. The biggest hurdles, however, are the capability and reliability of solar cells. Poor energy density and the spectrum in the bandgap of semiconductor phosphors do not match the energy allocation of the photons in solar spectra lines. These issues and cell efficacy must be addressed before photovoltaic cells can be developed as a viable source of electrical power. The amount of energy generated per unit area depends linearly on cell efficiency. Hence, it makes sense to increase the efficiency rather than enhancing the space for solar cell installation. One well-known method for converting a high-energy photon into two or more lower-energy photons is “downconversion”, which makes use of the wide solar spectrum required for solar cells. The design maximizes the use of the entire sunlight spectrum, improving the efficiency of various solar cell types. This review article surveys how spectrum converters, especially lanthanide-based downconverters and downshifters will be developed. This review focuses on the current materials and methods used to enable the downconversion and downshifting processes in solar cells and some of the challenges in developing solar cells.

“…These pollutants prevent sunlight from entering the PV modules and thereby degrade the power generation efficiency. Therefore, various studies have been conducted of late to effectively prevent the surface pollution of PV modules [3–4]. The PV module surface coating materials that are currently under research must have anti-pollution functions and must endure severe temperature differences, and harsh physical (e.g., external shock) and chemical environments (e.g., animal excrement).…”

This study aimed to apply annealing processes during the coating of photovoltaic (PV) module glasses to PV modules already installed through an easy and simple procedure. Three types of annealing treatments were applied to PV module glasses, i.e., furnace, rapid thermal annealing (RTA) and torch. Among these, torch annealing, which can be easily carried out at PV module installation sites, was applied to PV module glasses using different numbers of repetition. Light transmittance, contact angle, anti-pollution characteristics, adhesion and hardness of the functional coating films after using different annealing treatment times and methods were measured, and it was confirmed that these characteristics varied depending on the annealing treatment times and methods. Through this, it was possible to optimize the process conditions that provide excellent anti-pollution characteristics and could be easily utilized at on-site PV modules.

In this study, functional coating film was fabricated on glass for photovoltaic (PV) modules to improve the anti-pollution characteristics of PV modules. The functional coating film applied to a glass substrate through the spray coating method was annealed at 300 °C for 10 min in H2, N2, Ar, O2, and vacuum ambient. The contact angle of the coated surface was measured and it was confirmed that the anti-pollution characteristics were improved as the contact angle decreased. The light transmittance was measured and it exhibited the most excellent characteristics in vacuum. The hardness and adhesion were measured as the mechanical characteristics and they were all excellent regardless of the annealing ambient. Based on the analyzed characteristics, the process conditions of functional coating films were optimized to improve the anti-pollution and mechanical characteristics. If the coating process optimized in this study is applied to PV modules based on these results, improvement in the anti-pollution characteristics can be expected.
