Sustainable production of potable water is one of the United Nations sustainable development goals set for 2030. Among available renewable energy resources, solar energy is abundantly available in most of the fresh water scarce rural and remote locations. Moreover, solar distillation units and solar photovoltaic (PV) modules have been acknowledged as suitable candidates for addressing rising fresh water and electricity demands in these regions. In recent years, researchers have proposed a number of novel hybrid solar distillation units where the solar PV modules are integrated with solar thermal distillation units in different ways to harvest both electric power and potable water. In this work, a detailed review highlighting the classification, working principle, performance and features of these novel hybrid units have been carried out. In most of these hybrid units, integration is highly beneficial for solar thermal distillation units rather than for PV modules. Direct utilization of PV module as absorber, condenser and reflector in solar stills has few drawbacks. However, indirect utilization like utilizing electric power and waste heat energy recovered from PV module in distillation units has posed significant distillate yield enhancement up to 300.0%. In some cases, the integrated PV module has even generated sufficient power for carrying out essential domestic activities. Integrated PV module's performance has also improved significantly in few studies but the magnitude of improvement has not been disclosed clearly in most of the studies as more focus has been given to distillation units rather than PV modules. However, these novel hybrid configurations have not been fully explored & optimized and their techno-enviro-economic aspects have not yet been disclosed in these available precious literatures and they are still available as a potential research gap.
可持续生产饮用水是联合国 2030 年可持续发展目标之一。在可用的可再生能源中，太阳能在大多数淡水短缺的农村和偏远地区都大量存在。此外，太阳能蒸馏装置和太阳能光伏 (PV) 模块已被公认为解决这些地区日益增长的淡水和电力需求的合适候选方案。近年来，研究人员提出了许多新型混合太阳能蒸馏装置，其中太阳能 PV 模块以不同的方式与太阳能热蒸馏装置集成，以同时收获电能和饮用水。在这项工作中，对这些新型混合装置的分类、工作原理、性能和特点进行了详细的回顾。在大多数这些混合装置中，集成对太阳能热蒸馏装置非常有益，而对 PV 模块则不然。将 PV 模块直接用作太阳能蒸馏器中的吸收器、冷凝器和反射器有一些缺点。然而，间接利用如利用 PV 模块中的电能和废热能量来提高蒸馏装置的产水率，最高可达 300.0%。在某些情况下，集成的 PV 模块甚至产生了足够的电力来进行基本的家庭活动。在少数研究中，集成的 PV 模块的性能也得到了显著提高，但在大多数研究中，并没有明确披露改进的幅度，因为更多的关注点放在了蒸馏装置上，而不是 PV 模块上。然而，这些新型混合配置尚未得到充分探索和优化，其技术环境经济方面在这些现有的珍贵文献中尚未披露，它们仍然是一个潜在的研究空白。
