Abstract:
We investigate the morphological and performance of organic photovoltaics based on blended films of alternating poly(thiophene-phenylene-thiophene) and [6,6]-phenyl-C(71)-butyric acid methyl ester (PC(71)BM). The resulting fine-scale phase separation leads to enhanced performance and the highest power efficiency (6.4% under AM 1.5G (100 mW cm(-2))) when we use solvent annealing process.

Semiconductors
Metals such as copper (Cu), zinc (Zn), or lead (Pb) have low resistivity and feature conduction bands that are either not fully occupied or overlap with the valence band, making a bandgap non-existent. This allows electrons in the highest energy levels of the valence band to easily transition to the conduction band upon gaining...
