Power converters are key to the energy transition, and their main component is the power module. Emma Solà is a predoctoral researcher in PDS group, and the focus of her thesis is on improving the connections of the devices within the modules, in order to enhance their efficiency and reliability. She is studying the behaviour of sintered silver particles, which show very promising characteristics compared to lead-based solders (toxic for humans and environment). Concerning the top side conections of the device, she has set-up the necessary processes (in IMB-CNM clean room) to deposit thick copper layers, thus enabling the use of more advanced technologies that can improve the module’s performance. These improvements in chip connections will allow us to achieve energy savings in all their applications, such as sustainable mobility or renewable electricity generation, among many others.
