    摘要： Organic photovoltaic cells (OPVs) and their compositions are described herein. In one or more embodiments, the OPV or solar cell includes an anode; a cathode; a first active layer positioned between the anode and the cathode, the first active layer configured to absorb light in a first wavelength spectrum; a second active layer positioned between the anode and the cathode, the second active layer configured to absorb light in a second wavelength spectrum; and a recombination zone positioned between the first active layer and the second active layer.

    摘要： A highly efficient multi-junction photovoltaic device, such as a two, three, or four junction device, is disclosed. The multi-junction device may include a first subcell comprising a first photoactive region and a second subcell comprising a second photoactive region. The first and second photoactive regions are designed to minimize spectral overlap and maximize photocurrent across a broad absorption spectra, such as wavelengths ranging from 400 nm to 900 nm. The device may further include an interconnecting layer, disposed between the first subcell and the second subcell, that is at least substantially transparent. By introducing a transparent interconnecting layer, a dual element (tandem) cell achieves a power conversion efficiency of 10.0 ± 0.5%. By adding an additional (3 rd ) sub-cell that absorbs at the second order optical interference maximum within the stack. The triple-junction cell significantly improves the quantum efficiency at shorter wavelengths, achieving a power conversion efficiency of 11.1 ± 0.5%. Adding additional sub-cells has been shown to increase power conversion efficiency above 12%.

    摘要翻译： 公开了一种高效率的多结光伏器件，例如两个，三个或四个接合器件。 多结器件可以包括包括第一光活性区域的第一子电池和包括第二光活性区域的第二子电池。 第一和第二光活性区域被设计成使光谱重叠最小化并且在宽吸收光谱（例如400nm至900nm的波长）之间最大化光电流。 设备还可以包括布置在第一子电池和第二子电池之间的互连层，其至少是基本上透明的。 通过引入透明互连层，双元件（串联）单元实现10.0±0.5％的功率转换效率。 通过添加在堆叠内吸收二阶光学干涉最大值的附加（第三）子单元。 三结电池在较短波长下显着提高了量子效率，实现了11.1±0.5％的功率转换效率。 已经显示添加附加子单元可以提高12％以上的功率转换效率。
