Nanotechnology based Polymerized Solar Cells and Screen-Printing Technique for Power Generation

Energy is central to improved social and economic well-being, and is indispensable to most industrial and commercial wealth generation. It is key for improving human welfare and raising living standards. Industrialization of developing countries like India needs more and more power to meet the demand of life amenities. The global demand for energy is increasing drastically. The previous primary sources of energy like fossil fuel, coal, diesel etc which are decreasing day by day due to energy demand and there is a global warming problem also. Even hydro, thermal, biomass, solar, wind energy are not permanent solutions for the rise in demand. So there is a need for non-conventional energy sources to fill the gap in an improved version of power conversion efficiencies. This is fulfilled by organic polymerized solar cells, which have brought and gained the attention of practical large-scale users' minds to meet the energy required for work life. This paper explains nanotechnology application for energy storing and implementation of polymer technique to the plastic solar cells and also screen-printing technology in the fabrication of organic based bulk heterojunction solar cells.

Enhanced power-conversion efficiency in organic solar cells incorporating copolymeric phase-separation modulators

Fullerene–oligothiophene copolymers acting as donor/acceptor segregation modulators improve the device efficiency, giving the highest values for P3HT:PCBM plastic solar cells.

PBDTTPD for plastic solar cells via Pd(PPh3)4-catalyzed direct (hetero)arylation polymerization

Pd(PPh3)4-catalyzed direct (hetero)arylation polymerization (DHAP) affords PBDTTPD in higher molar mass than Stille coupling. PDHAP-based solar cells display PCE up to 5.3%.
