Abstract

A thin film photovoltaic structure has a substrate, a first conductive layer, a photovoltaic layer, a second conductive layer, multiple serial connection conductive layers and multiple first insulating areas. By using the serial connection conductive layer, each width between each adjacent serially connected photovoltaic structures is reduced, and an effective area of the thin film photovoltaic structure for collecting optic energy is increased, thus enhancing a geometry fill factor of the thin film photovoltaic structure. Further, by using the serial connection conductive layer and the first insulating area to form contact overlap areas in an overlapping arrangement, it can effectively protect conductive areas in the first conductive layer when etching the second conductive layer during the manufacturing process, which prevents the conductive areas from being damaged to not act as electrodes, and efficiently increases a manufacture yielding rate of the thin film photovoltaic structure.

Abstract

An aqueous electrolyte solution, a power storage device filled with the aqueous electrolyte solution, and a manufacturing method of the power storage device are illustrated. The aqueous electrolyte solution comprises alkali metal cations of different types. With the hydration enthalpy of the alkali metal cations of the different types, a simulated boiling point of the aqueous electrolyte solution is higher than the 105° C. of the conventional aqueous electrolyte solution. After processed by the reflow furnace at 250° C., the power storage device has no cracks found on its appearance, which meets the electrical requirements, and overcomes the problem of bursting of the power storage device filled with conventional aqueous electrolyte solution. The housing of the power storage device adopts liquid crystal polymer, and/or the power storage device is firstly vacuumed and then packaged, therefore increasing coulombic efficiency of electrical testing of the power storage device.
