Ítem Global energy assessment of the potential of photovoltaics for greenhouse farming(Elsevier Ltd, 2022-03-01) Fernández-Fernández, Eduardo; Villar-Fernández, Antonio; Montes-Romero, Jesús; Ruiz-Torres, Laura; Rodrigo, Pedro Manuel; Manzaneda, Antonio José; Almonacid-Cruz, Florencia MarinaAgrivoltaic (APV) systems have emerged as a promising solution to reduce the land-use competition between PV technology and agriculture. Despite its potential, APV is in a learning stage and it is still necessary to devote big efforts to investigate its actual potential and outdoor performance. This work is focused on the analysis of APV systems in agriculture greenhouses at global scale in terms of energy yield. To conduct this study, we introduce here a novel dual APV model, which is projected in four representative locations with a high crop cultivation greenhouse implantation, i.e. El Ejido (Spain), Pachino (Italy), Antalya (Turkey) and Vicente Guerrero (Mexico), and for 15 representative plant cultivars from 5 different important socioeconomic families of crops, i.e. Cucurbitaceae, Fabaceae, Solanacae, Poaceae, Rosaceae. At this stage, semi-transparent c-Si PV technology has been considered due its high efficiency and reliability. The results show that APV systems could have a transparency factor around 68% without significantly affecting the total crop photosynthetic rate. Taking this into account, APV systems would produce an average annual energy around 135 kWh/m2, and values around 200 kWh/m2 under a favourable scenario. This could represent a contribution to the total market share between 2.3% (México) and 6% (Turkey), and up to 100% of the consumption demand of greenhouses equipped with heating and cooling (GSHP), and lighting.Ítem High-power optical photovoltaic transmission: towards a new paradigm(ELSEVIER, 2025-11) Sanmartín, Pablo; Fernández-Fernández, Eduardo; García-Loureiro, Antonio Jesús; Almonacid-Cruz, Florencia MarinaHigh-power optical transmission (HPOT) holds transformative potential for revolutionizing energy delivery, offering a groundbreaking leap forward in how power is supplied and accessed. By utilizing a monochromatic light source as emitter and an optical photovoltaic converter as receiver, HPOT systems enable the sustainable transfer of kilowatts of power over hundreds of kilometers, overcoming the limitations of conventional copper wiring. This technology unlocks an extensive range of applications, from underwater environments to outer space, while driving disruptive advances in strategic fields such as energy supply, defense, communications, and healthcare. This work provides a comprehensive review of HPOT systems, including both optical wireless power transmissions and power-over-fiber systems. It begins with a historical overview and a description of the key performance indicators of the technology, followed by an evaluation of suitable high-power light sources. Then, the physical phenomena affecting light propagation are examined, as well as tracking mechanisms and safety measures that must be considered. Next, the photovoltaic receiver is analyzed in terms of intrinsic and extrinsic losses, and a comprehensive compilation of state-of-the-art performance results is presented. Finally, terrestrial and space prospective applications are explored, along with a survey of HPOT demonstrations conducted to date. Through a detailed research of the advantages, challenges, and key achievements of HPOT technology, this review aims to provide valuable insights to accelerate its development and adoption, paving the way for a more connected and sustainable future.
