Underwater photovoltaic (PV) systems supported with modern‐day technology can lead to possible solutions for the lack of long‐term power sources in marine electronics, navy corps, and many other remotely operated underwater power systems. Currently, most of these systems are powered by conventional batteries, which are bulky, costly, and require periodic maintenance and replacement. Harnessing the underwater Solar energy by using Solar PV cells is simple, reliable, and leads to tremendous advantageous as water itself provides cooling, cleaning, and avoid challenges due to land constraints. The present work encompasses an experimental study on Solar radiation in water and its changes with varying water conditions. Accordingly, the performance of monocrystalline and polycrystalline silicon solar cells with different submerged water conditions and water depths up to 20 cm has been studied. Most importantly, these studies have been carried out with different types of water conditions, consisting of salinity, bacteria, algae, and other water impurities. These investigation results manifest that the percentage decrease of maximum power output in monocrystalline and polycrystalline Solar cells is 65.85% and 62.55%, respectively, in the case of ocean water conditions, whereas in deionized (DI) water conditions, it is 63.06% and 60.72% up to 20 cm. Such results conclude that valuable amount of Solar energy is can be explored underwater. These experimental studies pave the way to explore further to utilize Solar PV cells efficiently in underwater conditions.

浸没式单晶和多晶太阳能电池的太阳辐照度研究和性能分析

受现代技术支持的水下光伏（PV）系统可能会导致可能的解决方案，因为船用电子产品，海军陆战队和许多其他远程操作的水下电力系统缺少长期电源。当前，这些系统中的大多数由常规电池供电，该常规电池体积大，价格昂贵并且需要定期维护和更换。通过使用太阳能光伏电池来利用水下太阳能非常简单，可靠，并且由于水本身可提供冷却，清洁并避免由于土地限制而带来的挑战，因此具有巨大的优势。目前的工作包括对水中太阳辐射及其随水的变化而变化的实验研究。因此，研究了不同浸水条件和水深达20 cm的单晶硅和多晶硅太阳能电池的性能。最重要的是，这些研究是在不同类型的水条件下进行的，这些条件包括盐度，细菌，藻类和其他水杂质。这些研究结果表明，在海水条件下，单晶和多晶太阳能电池的最大输出功率降低的百分比分别为65.85％和62.55％，而在去离子（DI）水条件下分别为63.06％和60.72。％可达20厘米。这些结果表明，可以在水下探索有价值的太阳能。这些实验研究为进一步探索在水下条件下有效利用太阳能光伏电池铺平了道路。
