The application of two-dimensional MoSe₂ atomic layers to the lift-off process is proposed for the preparation of light-weight and flexible bifacial Cu(In, Ga)Se₂ (CIGS) solar cells. The results show that CIGS solar cells are successfully peeled from a Mo rear contact when the c-axis of the MoSe₂, formed between the Mo and CIGS layers, is vertically oriented to the Mo surface. In this study, 11.5% efficient lift-off cells are fabricated, indicating a high-performance ratio of 95.0% compared with the 12.1% efficient substrate cells, thereby suggesting the usefulness of layered-grown MoSe₂ for the lift-off procedure. Finally, by applying the lift-off process, light-weight and flexible bifacial CIGS solar cells utilizing thin Au and Sn-doped In₂O₃ back contacts are derived.

二维MoSe ₂原子层在剥离生产轻质柔性双面Cu（In，Ga）Se ₂太阳能电池中的应用

提出了二维MoSe ₂原子层在剥离过程中的应用，以制备轻质柔性双面Cu（In，Ga）Se ₂（CIGS）太阳能电池。结果表明，当在Mo和CIGS层之间形成的MoSe ₂的c轴垂直于Mo表面时，CIGS太阳能电池成功地从Mo后接触中剥离。在这项研究中，制造了11.5％的高效剥离电池，表明与12.1％的高效基质电池相比，其高性能率为95.0％，从而表明了分层生长的MoSe ₂的有用性用于提起程序。最后，通过应用剥离工艺，获得了利用薄的Au和Sn掺杂的In ₂ O ₃背接触的轻量且柔性的双面CIGS太阳能电池。
