“…Planar crystalline Si terrestrial PV modules manufactured using the conventional lamination technology lose up to 15-20% of their maximum power at STC after 20 years of operation in tropical climates and after 25 years of operation in temperate climates. One of the reasons for it is the degradation of optical polymeric encapsulants such as ethylene vinyl acetate (EVA) and other plastics induced by ultraviolet radiation and high temperatures [47].…”

Developing an energy supply based on resources whose use does not spoil the noosphere and the creation of such energy supply of efficient equipment whose operation does not cause any damage to nature and man is an urgent task. The need for such an approach is especially relevant and noticeable in agriculture. This article presents the final results of complex studies of new PV devices and PV systems based on them. Considered in the article are the best solutions we propose to improve PV equipment and make it more attractive for agricultural consumers. The developed vertical and planar high-voltage multijunction silicon PV cells and PV modules on their basis are presented. The first type of modules have a maximum power point voltage of up to 1000 V, specific power of up to 0.245 ± 0.01 W/cm2, and efficiency of up to 25.3% under a concentration ratio range of 10–100 suns. The samples of the second module type (60,156.75 × 156.75 mm PV cells) have an open-circuit voltage of 439.7 V, a short-circuit current of 0.933 A, and a maximum power of 348 W. Additionally, two types of newly designed solar energy concentrators are described in this article: one-dimensional double-wing concentrator ensuring low Fresnel optical losses and multi-zone parabolotoric microconcentrator with the uniform radiation distribution in the focal region, as well as modules based on these concentrators and the developed PV cells. For PV modules, the maximum power degradation is 0.2–0.24% per year in a wet ammonia environment. For concentrating PV modules, this degradation is 0.22–0.37% per year. This article sets out the principles of increasing the efficiency of PV systems by increasing the level of systematization and expanding the boundaries of PV systems. The thus-created PV systems satisfy 30–50% more consumer needs. Thanks to a higher output voltage and other specific features of the developed modules, PV system loss decreased by 12–15%, and maintenance losses also decreased.

Although solar energy is a green energy, it can produce a significant amount of waste. Some types of solar cells use rare elements or precious metals as the component material. Therefore, the recycling of PV modules is necessary for environmental and economic purposes. The recycling process for PV modules includes chemical and physical treatment methods, which have been successfully used in other recycling industries, such as electronics or hardware recycling. The use of these mature technologies can decompose and recycle PV module materials. There are still some differences between PV module recycling and electronic recycling. A solar cell module contains several encapsulating plastic materials, such as ethylene vinyl acetate (EVA) and polyvinyl fluoride (PVF). In recycling programs, removing the plastic materials is the first step. In this chapter, several types of recycling processes are introduced, which correspond to different types of PV modules. These methods have been validated and successfully implemented in PV module recycling plants.

“…14 Many things were learned while developing the methodology that influenced the development of L&DS study procedures. 15 A key idea is to avoid destructive measurement techniques that cause samples to be dropped out of the study and create non-coincident observations of variables. Although sample loss due to destructive testing caused half of the UL dataset to be unusable for semi-gSEM, the data which could be modeled indicated two mechanistic degradation pathways of interest ( Fig.…”

The expected lifetime performance and degradation of photovoltaic (PV) modules is a major issue facing the levelized cost of electricity of PV as a competitive energy source. Studies that quantify the rates and mechanisms of performance degradation are needed not only for bankability and adoption of these promising technologies, but also for the diagnosis and improvement of their mechanistic degradation pathways. Towards this goal, a generalizable approach to degradation science studies utilizing data science principles has been developed and applied to c-Si PV modules. By combining domain knowledge and data derived insights, mechanistic degradation pathways are indicated that link environmental stressors to the degradation of PV module performance characteristics. Targeted studies guided by these results have yielded predictive equations describing rates of degradation, and further studies are underway to achieve this for additional mechanistic pathways of interest.
