Localized photovoltaic investigations on organic semiconductors and bulk heterojunction solar cells
Newly synthesized organic electronics materials are often available in submicrogram amounts only. Photoelectrochemical scanning droplet cell microscopy is a powerful method that allows a comprehensive characterisation of such small amounts including oxidation, reduction potentials, doping, determination of charge carriers, band gap, charge capacity, over-oxidation sensitivity and many more. Loc...
متن کاملSpin-enhanced organic bulk heterojunction photovoltaic solar cells.
Recently, much effort has been devoted to improve the efficiency of organic photovoltaic solar cells based on blends of donors and acceptors molecules in bulk heterojunction architecture. One of the major losses in organic photovoltaic devices has been recombination of polaron pairs at the donor-acceptor domain interfaces. Here, we present a novel method to suppress polaron pair recombination a...
متن کاملBulk heterojunction organic solar cells based on merocyanine colorants.
Traditional low-molecular weight colorants that are widely applied in textile coloration, for printing purposes and nonlinear optics, now afford bulk heterojunction solar cells in combination with soluble C(60) fullerene derivative PCBM with power conversion efficiencies up to 1.7% under standard solar radiation.
متن کاملNanofi ber - Based Bulk - Heterojunction Organic Solar Cells
Bulk heterojunction organic photovoltaic (BHJ–OPV) devices have been the topic of ever increasing research efforts due to their potential to result in printable, inexpensive solar cells which can be processed onto fl exible substrates. [ 1–3 ] Typically, the active layer of the BHJ consists of an interpenetrating network of electrondonating conjugated polymers and electron-accepting fullerenes....
متن کاملCharge Carrier Recombination in Bulk Heterojunction Organic Solar Cells
Photovoltaic phenomenon was first observed by E. Becquerel (Becquerel) in 1839. He observed the electric current-lit silver electrode, immersed in the electrolyte. In 1894, taking advantage of the observed photoconductivity phenomenon in amorphous selenium the semiconductor solar cell was developed. The very first silicon p-n junction solar cell was made in 1954, energy conversion efficiency of...
