Are photovoltaic energy storage solutions realistic alternatives to current systems?

Due to the variable nature of the photovoltaic generation, energy storage is imperative, and the combination of both in one device is appealing for more efficient and easy-to-use devices. Among the myriads of proposed approaches, there are multiple challenges to overcome to make these solutions realistic alternatives to current systems.

Can photovoltaic devices and storage be integrated in one device?

This critical literature review serves as a guide to understand the characteristics of the approaches followed to integrate photovoltaic devices and storage in one device, shedding light on the improvements required to develop more robust products for a sustainable future.

Can a thin-film solid-state rechargeable battery be used as a harvesting device?

For instance, in Ye et al, 68 the fabrication and characterisation of a harvesting device that integrates a thin-film solid-state rechargeable battery was introduced, showing a 0.1%/cycle reduction on battery capacity and a generation-storage efficiency and maximum power point of 7.03% and 150 mW, respectively.

Are Battery integrated PV panels more efficient?

Consequently, it was found that in average, the PV panel with batteries integrated is 10 to 15° C hotter than PV panel without batteries; as a consequence, the battery integrated PV panel is 6% less efficient for a defined scenario.
