研究目的
To conduct an experimental study for investigating the underwater performance of a-Si based thin-film PV module. Electrical characteristics and their variation with respect to PV module immersion depths (shallow waters and deep waters) are evaluated.
研究成果
The performance of PV module is varied with respect to the immersion depths. The varied parameters include the voltage, current, and power output. As the PV module immersion depth increases the output power is reduced. As a result, the power conversion efficiency is reduced. Based on the performance results, it is understood that the output power is less in deep waters, hence the use of underwater photovoltaic systems can be encouraged for low power applications.
研究不足
The research on underwater photovoltaics is very much limited to performance studies itself. Future works might include on the efficiency improvement by having a detailed understanding over the spectral response, and thermal behavior of photovoltaics cells.
