-One of the most important characteristic curves of a solar cell is its current density-voltage (J-V) curve under AM1.5G insolation. Solar cell can be considered as a semiconductor diode, so a diode equivalent model was used to estimate its parameters from the J-V curve by numerical simulation. Active layer plays an important role in operation of a solar cell. We investigated the effect thicknesses and defect densities (N d ) of the active layer on the J-V curve. When the active layer thickness was varied (for N d = 8×10 17 cm -3 ) from 800 nm to 100 nm, the reverse saturation current density (J o ) changed from 3.56×10 -5 A/cm 2 to 9.62×10 -11 A/cm 2 and its ideality factor (n) changed from 5.28 to 2.02. For a reduced defect density (N d = 4×10 15 cm -3 ), the n remained within 1.45≤n≤1.92 for the same thickness range. A small increase in shunt resistance and almost no change in series resistance were observed in these cells. The low reverse saturation current density (J o = 9.62×10 -11 A/cm 2 ) and diode ideality factor (n = 2.02 or 1.45) were observed for amorphous silicon based solar cell with 100 nm thick active layer.

“…Depending on the type of mirror, that is flat or textured, the light trapping can be retro reflective or diffused reflective. Textured back reflector are preferable than a simple smooth BR 5,8,10) . In a textured BR, the reflected light remains diffused, thereby increasing average optical path length of reflected light within the cell and also raising a possibility of keeping more light outside the escape cone and thereby enhanced light trapping 10) .…”

“…Interestingly, the analysis 2) shows that the intensity of this confined light inside a non-absorbing textured film can be larger than the incident light intensity, implying that light absorption in such a film morphology can be enhanced. Since then a large number of investigations have been made on various types of solar cells, like single junction 5,6) , tandem [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] and triple junction solar cells [23][24][25][26] and considered as a state of the art technique to improve device performance.…”

Among the various types of solar cells, silicon based two terminal tandem solar cell is one of the most popular one. It is designed to split the absorption of incident AM1.5 solar radiation among two of its component cells, thereby widening the wavelength range of external quantum efficiency (EQE) spectra of the device, in comparison to that of a single junction solar cell. In order to improve the EQE spectra further and raise short circuit current density (Jsc) an optimization of the tradeoff between the top and bottom cell is needed. In an optimized cell structure, the Jsc and hence efficiency of the device can further be enhanced with the help of light trapping scheme. This can be achieved by texturing front and back surface as well as a back reflector of the device. In this brief review we highlight the development of light trapping in the silicon based tandem solar cell.
