Based on research on previous literature and looking at the success of other materials we propose two similar, yet different designs, illustrated in figure .  Both designs are based three main ideas:   1. **Buffer Layer** between the window and the front contact.   2. Novel materials for back contacts. \cite{Matin_2010}  3. Distributed Bragg Reflectors as a back mirror to increase photon recycling.\cite{Khosroabadi_2014}  ## Buffer Layer  transparent conductive oxide
