In the PV system with storage batteries, as a maximum power point tracking (MPPT) device is used to enhance battery charging, the enhancement must be greater than the internal loss of the device itself, or there will be no net gain at all. To evaluate the MPPT device benefits under different...

A novel structure of dye-sensitized solar cell (DSSC) with integrated photoanode was first reported in this paper. Titanium threads and titanium sheet were first used in this novel structure in place of traditional glass substrate, thus reducing the series resistance of the substrates. An...

Here we report a 3-dimensional dye-sensitized solar cell (3D-DSSCs) and module simulating the fractal structure of the pine tree for capturing sunlight. Compared to traditional flat solar cells, this type of solar cell exhibits superiority of absorbing sunlight from all directions. The...

Selective emitter for silicon solar cell was realized by employing a-Si thin films as the semi-transparent diffusion barrier. The a-Si thin films with various thicknesses (∼10–40nm) were deposited by the electron-beam evaporation technique. Emitters with sheet resistances from 37 to...

Well-aligned hierarchical TiO2 tubular macrochannel arrays (HTTMAs) with high surface area have been synthesized via a facile one-step ammonia hydrothermal synthesis process without using any structure-directing templates. The typical samples are made of an assembly of macrochannels with uniform...
