Abstract: The present disclosure relates to a perovskite-containing solar cell module that includes a glass substrate; a first cell; and a second cell, where each cell includes, in order, a first contact layer that includes fluorine-doped tin oxide, positioned on the substrate, and having an outside surface and a first thickness; an electron transfer layer that includes TiO2 and having a second thickness between 1 nm and 10 ?m; an active layer that includes the perovskite and having a third thickness; a hole transfer layer that includes spiro-OMeTAD and having a fourth thickness; and a second contact layer that includes copper and having a fifth thickness. In addition, the first cell and the second cell are electrically connected by a first gap filled with the copper, and the first gap passes through the third thickness, the fourth thickness, and substantially through the second thickness to terminate at the outside surface.

Abstract: Transparent and conductive adhesive (TCA) materials that may be incorporated into various devices are provided. According to an aspect of the invention, a device includes a first layer, a second layer, and a third layer including a TCA material. The third layer is arranged between the first layer and the second layer, and is configured to provide electrical conductivity between the first layer and the second layer. The TCA material includes conductive elements dispersed within a transparent adhesive, and the conductive elements are deformable.
