Wearable Photovoltaic Applications as Energy Sources for Everyday Devices

Solar technology since its first implementation for energy production has evolved in numerous directions to become part of a normal reality in future energy systems. The people’s energetic consumption changed as well. In the present days, people use portable devices more than ever, such as mobile phones and laptops and to power these portable devices, batteries are used. But what if we did not use batteries? or what if we could just keep charging our portable devices on the go? Flexible solar cells’ efficiency has been increasing throughout the years, especially the perovskite material that in the last years have reached a power conversion efficiency above the 20% mark. This opened the possibility to tackle other areas that traditional solar cells could not, including the possibility to use solar cells as a wearable source of power for our daily gadgets. Three types of materials will be shown as wearable solar cells and the evolution of perovskite material will be presented in order to set the state-of-art for future works in this domain.
