【解決手段】大量生産されるDSSCを実現するにあたっての制約の1つは、良好なアラインメントを提供する高解像度パターニング技法が存在しないことである。本発明は、電気化学電池を製造するためにポリマー層上にパターン化された構造を作成するための方法を提供する。当該方法は、基板上にポリマー層を堆積させること、および、エンボス工具を用いてポリマー層にスタンプ加工を行い、それにより、エンボス加工されたポリマー層を形成することであって、エンボス工具は、隣接するセルの第1のアレイを有し、第1のアレイは互いに離間するとともに、エンボス工具のスタンプ面から延在し、それにより、隣接するセルの第2のアレイを形成し、第2のアレイは、互いに離間するとともに、エンボス加工されたポリマー層内部にキャビティとして延在する、スタンプ加工を行うことを含む。
【選択図】図5
