DYE-SENSITIZED TANDEM SOLAR CELLS COMPRISING TWO-SIDE ELECTRODE LINKED THROUGH VIA HOLE OF A COMMON SUBSTRATE

摘要

A dye-sensitized tandem solar cell comprising an upper solar cell and a lower solar cell formed on upper and lower portions of the first substrate, including electrode layers formed on both upper and lower surfaces of a first substrate which is a common substrate. The first substrate relates to a dye-sensitized tandem solar cell connected in series or in parallel, comprising one or more via holes coated or filled with a conductive material, for energizing electrode layers formed on both upper and lower sides. .
