Direct integration of photovoltaic device into circuit board

摘要

Aspects relate to an integrated system that is electrically powered. The integrated system includes a circuit board and a photovoltaic device. The circuit board includes one or more on-board electronic components and an upper surface configured as a substrate. The photovoltaic device is integrally deposited on the upper surface of the circuit board and electrically connected to the one or more on-board electronic components, wherein the upper surface of the circuit board is a photovoltaic device substrate.
