Photovoltaic devices having contact layers are described herein. Devices, intermediate structures, and methods for making multilayer contacts for perovskite photovoltaic devices are provided. Embodiments include back contacts for N-I-P structures.

Solar cell modules and methods of fabrication are described. In an embodiment, a pair of tandem solar cells are a step surface or trench within the top subcell of a tandem solar cell is at least partially filled with another material such as an insulator support or electrically conductive support to transfer stress away from the absorber layer of the top subcell of the tandem solar cells when stacked or connected with ribbon.

A detection device includes: an active area including an active layer; a coupling area with a coupling part provided at an end of a first substrate; a peripheral area between the active area and the coupling area; a sealing film sealing the active area and the peripheral area; and a first wiring line coupling a lower electrode to the coupling part. The peripheral area includes: a first portion including the first insulating layer, the sealing film, the second insulating layer, and the second substrate; and a second portion including at least one of the sealing film, the second insulating layer, and the second substrate as compared with the first portion. The first wiring line intersects a boundary line provided between the first and second portions along a longitudinal direction of the second substrate formed in a band shape that intersects a direction from the coupling area toward the active area.
