AB  - Solar cell in combination with a secondary battery is a straightforward power supply solution for portable electronics. When used indoors or outdoors under sufficient illumination conditions the combination is attractive to realize self-sustained devices or extend off-grid operation time. However, only little fraction of widely spread portable devices worldwide are equipped with PV energy harvesters. Besides low-average power, combination of discrete PV module and battery is bulky for extreme demands in modern portable electronics. Integration of thin-film solar cell with a thin-film storage cell in a monolithic, customizable module is a viable option. The low level cell-to-cell integration is possible with thin-film silicon multi-junction solar cells providing sufficient voltage to charge Li-ion storage cell. In this work, we focus on the development of triple-junction thin-film silicon solar cells for monolithic integration with lithium ion storage cells. We show that with appropriate voltage matching a triple junction thin-film silicon solar cell provides efficient charging for lab-scale Li-ion storage cell under a range of illumination intensities. Maximum solar energy-to-battery charging efficiency of 8.8% was obtained.
