Hole-Transport Materials for Perovskite Solar Cells.
The pressure to move towards renewable energy has inspired researchers to look for ideas in photovoltaics that may lead to a major breakthrough. Recently the use of perovskites as a light harvester has lead to stunning progress. The power conversion efficiency of perovskite solar cells is now approaching parity (>22 %) with that of the established technology which took decades to reach this lev...
متن کاملChemically modified graphene oxides as a hole transport layer in organic solar cells.
We demonstrate O(2) plasma treated graphene oxides with a work function of 5.2 eV as a high performance hole transport layer in organic solar cells. The high transparency and high work function simultaneously increase short circuit current, threshold voltage and fill factor, resulting in a 30% increase in cell efficiency.
متن کاملGraphene oxide hole transport layers for large area, high efficiency organic solar cells
Graphene oxide (GO) is becoming increasingly popular for organic electronic applications. We present large active area (0.64 cm 2), solution processable,
متن کاملA dopant-free organic hole transport material for efficient planar heterojunction perovskite solar cells
We demonstrate efficient planar perovskite solar cells using a dopant-free donor–acceptor (D–A) conjugated small molecule as a hole transport material. The photovoltaic cell reaches a power conversion efficiency (PCE) of 14.9%, which is comparable to or even better than that of the devices using the traditional doped 2,20,7,70-tetrakis(N,N0-di-p-methoxyphenylamine)-9,90-spirobifluorene (spiroOM...
متن کاملGraphene quantum dots as the hole transport layer material for high-performance organic solar cells.
We present an investigation of organic photovoltaic (OPV) cells with solution-processable graphene quantum dots (GQDs) as hole transport layers (HTLs). GQDs, with uniform sizes and good conductivity, are demonstrated to be excellent HTLs in both polymer solar cells (PSCs) and small-molecule solar cells (SMSCs) with the blend of poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (...
