Beschreibung
Zusammenfassung:A hybrid photovoltaic device (1) comprising a thin film solar cell (2) disposed in a first layer (21) comprising an array of vertically aligned nanowires (25), said nanowires having a junction with a first band gap corresponding to a first spectral range., The nanowires (25) form absorbing regions, and non-absorbing regions are formed between the nanowires. A bulk solar cell (3) is disposed in a second layer (31), positioned below the first layer (21), having a junction with a second band gap, which is smaller than said first band gap and corresponding to a second spectral range. The nanowires are provided in the first layer with a lateral density selected a such that a predetermined portion of an incident photonic wave-front will pass through the non-absorbing regions without absorption in the first spectral range, into the bulk solar cell for absorption in both the first spectral range and the second spectral range. 用于薄膜太阳能电池的层结构和制造方法。本发明涉及种用于薄膜太阳能电池(1)的层结构,包括光伏吸收剂层(5),所述光伏吸收剂层(5)至少在与光伏吸收剂层的表面(6)邻近的区域中掺杂有至少
