Thin Onboard Power Storage for Photovoltaics (TOPS-PV).
Abstract
Thin Onboard Power Storage for Photovoltaics (TOPS-PV) is a concept where a thin, flexible battery is placed onto a thin, flexible photovoltaics device, thereby consolidating both electrical power generation and power storage. Flexible PV has been demonstrated in both amorphous silicon (aSi) and copper indium selenide (CIS), as well as laboratory scale flexible solid state lithium ceramic batteries. However, no attempt has been reported at combining the two technologies. This concept would reduce the cost, weight, and storage volume of both the PV array and the battery storage required in the spacecraft bus. The TOPS-PV program investigated the combination of the solid state battery and aSi to determine the compatibility of the two technologies with regard to roll to roll manufacture. Phase I investigated the PV battery stack using existing PV devices and sputtering, chemical vapor deposition, and evaporation battery processing techniques.
