This contribution demonstrates the effects of mole ratio, concentration perovskite components and fullerene derivatives used as electron transport layer (ETL) on stability performances inverted solar cells (PSCs). C60, C70, PC61BM PC71BM are selected ETL materials. Methylammonium iodide (MAI):Lead (II) (PbI2):Lead(II) chloride (PbCl2) to form MAPb2I2Cl which is a mixed halogen structure. The fa...
Solar cells based on p-conjugated donor-acceptor (D-A) organic molecular systems are a promising alternative to conventional electrical energy generation. D-A systems, which have triphenylamine (TPA) moiety linked with benzothiadiazole (BTD) moiety, open the potential development of new small molecule donors for bulk heterojunction (BHJ) solar cells. Here, series donor-acceptor-π-acceptor (D-A-...
Light and flexible photovoltaic devices based on organic materials are extensively studied as an alternative to expensive and fragile silicon-based solar cells. The efficiency of these devices is rapidly increasing with the most recent power conversion efficiency (PCE) of greater than 8% bringing them closer to commercial viability. Further improvements are needed and can be achieved by optimiz...
Polymer bulk heterojunction (BHJ) solar cells consisting of the photoactive layer containing the interpenetrating network of electron donating polymer and electron accepting PC71BM has been proved to be quite effective in converting the solar energy into electrical energy. After many efforts, the power conversion efficiency (PCE) of the polymer solar cells (PSCs) was improved up to 9.2%. Unfort...
