Interlayers for Solar Cells

Project: Highly transparent, stable, and highly conductive interlayers for solar cells

PI: Thomas Anthopoulos, Frederic Laquai, Stefaan De Wolf, Jr-Hau He

Functional interlayers represent an indispensable element of several emerging optoelectronic device technologies including, organic light emitting-diodes, photodetectors, and solar cells, to name but a few. The materials used to prepare such functional layers need to combine several important properties such as high optical transparency, high electrical conductivity, suitable energy levels, processing compatibility, and reliability, while avoiding use of toxic and scarce elements. 
The aim of this project is to develop advanced interlayer material systems with improved opto-electronic properties compared to current state-of-the-art and to prove their applicability in high-performance 3rd generation photovoltaic devices. To achieve this, a variety of deposition techniques, including solution-based processing, vacuum sublimation, atomic layer deposition and sputtering, will be employed. The advanced interlayers will be optimized and tested in different baseline processes available within KAUST Solar Centre, including organic, silicon heterojunction and perovskite solar cells.
