Organic photovoltaics (OPV) is an emerging technology that combines semi‐transparency and flexibility in lightweight, ultrathin solar modules. The record power conversion efficiencies for OPV are approaching 20%, with reported lifetimes ranging from months to several years. Despite these attributes, OPV has not yet been commercialized on a large scale. Here, we critically examine the commercial potential of OPV. We begin by surveying feasibility studies in the literature to identify threshold values for performance that would enable OPV to be commercially competitive with conventional electricity production. We discuss how these parameters alone are not sufficient to predict the success of a photovoltaic technology, as there is still significant discrepancy between performance in the laboratory and in the field. Even if this gap can be closed, it is unlikely that OPV will ever compete in the conventional electricity market. Instead, the unique properties may make OPV an interesting candidate for niche applications with less rigid demands on performance, but stricter requirements on aesthetics, flexibility, weight, and transparency. In this case, application‐specific requirements on efficiency and stability must first be established. Ultimately, even the most optimistic scenarios for OPV identify poor stability as the biggest challenge for general market entry.

“…The failure of the encapsulation was identified as the main cause of the degradation. Krebs and co‐workers have also explored OPV module lifetime in a greenhouse and found that module lifetime was enhanced slightly; a result that suggests possible new applications for OPVs.…”

Current Status of Outdoor Lifetime Testing of Organic Photovoltaics

Performance degradation is one of the key obstacles limiting the commercial application of organic photovoltaic (OPV) devices. The assessment of OPV stability and lifetime are usually based on simulated degradation experiments conducted under indoor conditions, whereas photovoltaic devices experience different environmental conditions under outdoor operation. Besides the intrinsic degradation of OPV devices due to the evolution of optoelectronic and morphological structure during long‐term operation, outdoor environmental changes can impose extra stresses and accelerate the degradation of OPV modules. Although outdoor studies on long‐term OPV stability are restricted by the long data collection times, they provide direct information on OPV stability under mixed degradation stresses and are therefore invaluable from the point of view of both research and practical application. Here, an overview of the current status of outdoor lifetime studies of OPVs is provided. After a summary of device lifetime extrapolated from indoor studies, outdoor lifetime testing platforms are introduced and the operational lifetime of various OPV devices are reviewed. The influence of climate and weather parameters on device performance and burn‐in phenomena observed during the degradation of OPVs is then discussed. Finally, an outlook and directions for future research in this field are suggested.

“…Ravishankar et al [113,114] reported that there are benefits of integrating semi-transparent OPV to meet energy demand of greenhouses in warm and moderate climates, being a potential candidate to achieve net-zero energy greenhouses. Intensive research on OPV greenhouses currently focuses on developing new optimized devices that minimize the impact on crop yield [115][116][117][118][119], to evaluate performance in real operational conditions [120][121][122][123][124] and to study of the environmental impacts through the life cycle assessment (LCA) methodology [125][126][127]. Variation in color and transparency are characteristics that can be also achieved by DSSC technology being a potential candidate to be considered as a photo-selective covering for a greenhouse [128][129][130][131][132][133][134].…”

Agrivoltaic Systems Design and Assessment: A Critical Review, and a Descriptive Model towards a Sustainable Landscape Vision (Three-Dimensional Agrivoltaic Patterns)

As an answer to the increasing demand for photovoltaics as a key element in the energy transition strategy of many countries—which entails land use issues, as well as concerns regarding landscape transformation, biodiversity, ecosystems and human well-being—new approaches and market segments have emerged that consider integrated perspectives. Among these, agrivoltaics is emerging as very promising for allowing benefits in the food–energy (and water) nexus. Demonstrative projects are developing worldwide, and experience with varied design solutions suitable for the scale up to commercial scale is being gathered based primarily on efficiency considerations; nevertheless, it is unquestionable that with the increase in the size, from the demonstration to the commercial scale, attention has to be paid to ecological impacts associated to specific design choices, and namely to those related to landscape transformation issues. This study reviews and analyzes the technological and spatial design options that have become available to date implementing a rigorous, comprehensive analysis based on the most updated knowledge in the field, and proposes a thorough methodology based on design and performance parameters that enable us to define the main attributes of the system from a trans-disciplinary perspective.
