An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.

Force sensing architectures

Transparent conductors including a silver layer with high transparency and low sheet resistance are described. In some examples, the silver layer can be located between two transparent conductive oxide layers. The transparent conductor can further include additional transparent conductive oxide layers, optical layers, and/or additional conductive layers (e.g., layers including ITO or another fully or partially transparent conductive material), for example. In some examples, transparent conductors including a silver layer can be included in a touch screen device. For example, one or more shielding layers or one or more touch electrodes can include transparent conductors with a silver layer. In some examples, the silver layer can improve transparency, sheet resistance, and/or infrared reflection characteristics of the transparent conductor.

The present invention provides a method to form Group IBIIIAVIA solar cell absorber layers on continuous flexible substrates. In a preferred aspect, the method forms a Group IBIIIAVIA absorber layer for manufacturing photovoltaic cells by providing a workpiece having a precursor layer formed over a substrate, the precursor layer including copper, indium, gallium and selenium; heating the precursor layer to a first temperature; reacting the precursor layer at the first temperature for a first predetermined time to transform the precursor layer to a partially formed absorber structure; cooling down the partially formed absorber structure to a second temperature, wherein both the first temperature and the second temperature are above 400&#xb0; C.; and reacting the partially formed absorber structure at the second temperature for a second predetermined time, which is longer than the first predetermined time, to form a Group IBIIIAVIA absorber layer.
