Investigation of Organic Bulk Heterojunction Solar Cells from Optical Aspect

Nanofi 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....

Bulk 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.

Charge 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...

Multiparameter investigation of bulk heterojunction organic photovoltaics

A key parameter to improve the performance of organic solar cells is the optimization of electronic phenomena at donor–acceptor interfaces through the optimization of the morphology of the bulk heterojunction. The correlative mapping of morphological, electrical and mechanical properties at the nanoscale by advanced scanning probe microscopy techniques allows for a detailed characterization of ...
