Speech Title: Quantum theory of exciton dissociation in organic photovoltaic devices
Abstract: Sunlight is the most plentiful source of clean energy, providing to the earth in one hour enough energy for current human needs of one year. In addition, photovoltaic devices based on organic semiconductors possess many remarkable advantages in comparison with the inorganic technology, such as flexibility, transparency, low weight and inexpensive manufacture. Hence, understanding the kinetics of light-generated excitons around the organic donor-acceptor heterojunction may significantly improve the performance of such solar cells. In this talk, we present a quantum mechanical theory of molecular photocells based on a coarse-grained attractive Hubbard Hamiltonian, where the transport and dissociation of excitons are analyzed on an excitonic state lattice containing impurity sites originated from the attractive electron-hole interaction. The presence of these impurity sites prevents the use of reciprocal space and then, the numerical calculation was carried out by means of an independent channel plus real-space renormalization method, where the competition between the driving force from heterojunction and the Coulomb attraction leading to an electron-hole recombination has been explicitly addressed. The results reveal an optimal distance between molecular photocells to achieve the maximum quantum efficiency, in accordance with numerous experimental reports about the optimal concentration of donor molecules. Moreover, the calculated quantum efficiency has good agreement with those obtained from diverse organic photovoltaic devices, such as bilayer, perovskite and inverted solar cells. This research was partially supported by projects CF-2023-I-830, UNAM-IN110823 and LANCAD-UNAM-DGTIC-039.

Speech Title: Advancing Sustainable Food Security: The Role of Renewable Energy
Abstract: Global sustainable food security is a cornerstone of the Sustainable Development Goals (SDGs), yet in 2023 approximately 2.33 billion people are undergoing moderate to dreadful food insecurity, including 733 million suffering from hunger, according to a UN report. Concurrently, renewable energy is vital to achieving multiple SDGs, especially SDG 2 (Zero Hunger) and SDG 7 (Affordable and Clean Energy). In 2021, agriculture, forestry, fisheries, and aquaculture accounted for 15.4% of global energy consumption, with renewables supplying over 55% of this share. The causes of global food insecurity are multidimensional encompassing to climate change, shortage of irrigation, post-harvest waste, regional conflicts, and lack of infrastructure, particularly in low and middle‑income nations. Innovative renewable energy solutions are proving critical: off‑grid solar-powered irrigation can double or triple yields, and micro‑hydropower is powering agro-processing. In many countries, food waste has been a crucial issue due to the lack of cold storage and food processing facilities. As of 2022, in India about 40% of the food produced was wasted due to the lack of cold storage. Additionally, solar cookstoves in Zambia have cut household fuel costs, easing nutrition-related expenditure constraints. This presentation explores barriers such as high cost, policy gaps, and infrastructure deficits while highlighting scalable renewable-energy-driven solutions like agrivoltaics, solar-powered irrigation, solar thermal food drying, cold storage systems, and off-grid microgrids. By focusing on practical, context-specific innovations, the aim is to illustrate how renewable energy can significantly advance food security in underdeveloped and developing countries.

Speech Title: Real-Time Wideband Dynamic Measurement In Embedded System
Abstract: Aiming at the application challenges of high-precision wideband dynamic measurement methods in embedded measurement devices with limited computing resources and lacking native support for complex-valued operations for new energy grids, the real-valued fast measurement method for wideband dynamic signals is proposed and applied in the embedded system. There is no need for special real-valued processing of complex-valued programs according to the specific type of embedded system, resulting in low computational complexity and minimal memory overhead. Through the measurement analysis of field wideband oscillation recorded signals and practical tests on domestic embedded systems, the engineering applicability of the proposed method is verified.
