Effect of Mixed Layer Crystallinity on the Performance of Mixed Heterojunction Organic Photovoltaic Cells. (8th February 2014) - Song, Byeongseop
Abstract Organic vapor‐phase deposition (OVPD) is used to grow tetraphenyldibenzoperiflanthen (DBP):C70 mixed heterojunction photovoltaic devices. Compared with vacuum thermal evaporation (VTE), the OVPD‐grown film develops nanocrystalline domains of C70. Optimized OVPD‐grown OPVs have a 61% fill factor for a 100 nm active layer thickness, whereas VTE‐grown devices have a 47% fill factor at the same thickness.
