Effects of thermal annealing of polymer:fullerene photovoltaic solar cells for high efficiency

Organic solar cells: Study of combined effects of active layer nanostructure and electron and hole transport layers

“…Up-todate, the highest performance OSC has been reported by Toshiba with power conversion efficiency (PCEΨ of 11±0.3% [11]. Among all the organic materials, P3HT:PCBM blends are the most investigated organic system for OSC applications; the highest recorded PCE for this system is found to be in the range of 4.5-6% [12][13][14]. Recently, we have reported several approaches based on different treatments of blends comprising P3HT:PCBM; these include, employing cosolvents to dissolve the active layer materials [15,16] with highest PCE recorded for a cosolvents treatment of chlorobenzene (CBΨ:chloroform (CFΨ (1:1Ψ is 2.73%.…”

Hybrid solar cells of conjugated polymers metal-oxide nanocrystals blends; state of the art and future research challenges in Indonesia

“…The choice of solvents can also affect the nanomorphology of blend polymer-inorganic nanocrystals and the PCE of hybrid solar cells. A post-production thermal annealing can also influence the nanomorphology of hybrid solar cells, as it was well-known method for improving crystallinity of conjugated polymer to provide conductive pathways and to improve hole mobility in P3HT:PCBM solar cells [17,19,53].

Structural, morphological, optical, and electrical transport studies of poly(3-methoxythiophene)/NiO hybrid nanocomposites

“…Another approach to improve the efficiency is the enhancement of spectral coverage and reduction in optical interference in the device. Because of the optical interference, the light intensity is zero at the electrode; thus, a large fraction of active layers is in dead zone in which the photogeneration of carriers is significantly reduced [13]. Incorporation of the inorganic nanocrystals into the device can expand the spectral coverage and apparently improve the performance of the device.…”
