Highly concentrated photovoltaic (HCPV) systems exploit concentrated solar flux using cheap optical components in lieu of large area, expensive photovoltaic cells. However, HCPV chips - due to their higher energy flux - generate considerable amount of waste heat which lowers their energy conversion efficiency. Novel microscale water cooling systems (i.e. microfluidic chips) can effectively regulate the photovoltaics cell temperature, thereby enhancing the cell energy efficiency. Additionally, the heat extracted by the coolant can be reused in: a. Food and Pharmaceutical stage: to run an absorption refrigeration unit (where evaporation of a working fluid causes cooling) for food preservation and storage of vaccines, that require considerable energy use.b. Water: membrane based water desalination processes to make saline water suitable for domestic and agricultural use c. Fuel: for efficient production biodiesel Integrating water cooled HCPV systems with one or more of these waste heat recovery technologies can have major positive impact on water, energy, food, healthcare and environmental challenges faced by Brazil - this is very well-aligned with the 'Food energy water environment nexus' theme.

高聚光光伏 (HCPV) 系统使用廉价的光学元件代替大面积、昂贵的光伏电池，利用聚光太阳能通量。然而，HCPV 芯片由于其较高的能量通量，会产生大量废热，从而降低了其能量转换效率。新型微型水冷系统（即微流控芯片）可以有效调节光伏电池温度，从而提高电池能量效率。此外，冷却剂提取的热量可重新用于：食品和制药阶段：运行吸收式制冷装置（其中工作流体的蒸发导致冷却）用于食品保存和疫苗储存，这需要大量的能源使用。水：基于膜的水淡化工艺，使盐水适合家庭和农业使用 c．燃料：用于高效生产生物柴油将水冷 HCPV 系统与一种或多种废热回收技术相结合，可以对巴西面临的水、能源、食品、医疗保健和环境挑战产生重大积极影响 - 这与“食品能源水环境关系”主题非常吻合。
