Global Research Activities for Harvesting Solar Energy (A Review)

The increasing importance of environmental concern, fuel savings and unavailability of power has led to the renewal of interest in renewable energies. This paper examines global research patterns to assess development prospects. The various new and advanced methods to harness solar energy and also the methods to increase the efficiency of the existing techniques are discussed.

Dye-Sensitized Solar Cell for Energy Harvesting Applications

A dye-sensitized solar cell (DSC) has unique properties that the cell performance does not readily decrease even at higher incident light angles compared with a Si solar cell and dose not decrease or rather increases under low light conditions. Fujikura is developing new applications of DSC by taking advantages of these properties to the field of “Energy Harvesting” where rapid growth of market...

Harvesting UV photons for solar energy conversion applications.

We report the synthesis and characterization of five new donor–π–spacer–acceptor dye molecules with a diphenylamine donor, fluorene–1,2,5-oxadiazole spacers and a range of acceptor/anchor groups (carboxylic acid 1, cyanoacrylic acid 2 and 3, alcohol 4 and cyano 5) to facilitate electron injection from the excited dye into the TiO2 photoanode in dye-sensitized solar cells (DSSCs). Detailed photo...

A Bridge Voltage Doubler Ac/dc Converter for Low-voltage Energy Harvesting Applications

Efficient ac/dc rectification of low voltages is critical for the realization of fully-functional vibrational energy harvesting systems. This paper presents the design and experimental characterization of low-power ac/dc converter designed to operate with very low input voltage amplitudes (as low as 20 mV) for magnetic induction energy harvesters. The bridge voltage doubler provides a dc output...
