Abstract EN
A series of etching experiments on light trapping structure have been carried out by glass etching.
The block structure provides long light traveling path and a constant distance between the cathode and anode electrodes regardless of the block height, which results in higher efficiency of the block textured solar cell.
In terms of etching profile of the glass substrate, the addition of NH4F resulted in the smooth and clean etching profile, and the steep slope of the block was obtained by optimizing the composition of etching solution.
For a higher HF concentration, a more graded slope was obtained and the addition of HNO3 and NH4F provided steep slope and clean etching profile.
The effects of the block textured glass were verified by a comparison of the solar cell efficiency.
For the textured solar cell, the surface was much rougher than that of the plain glass, which also contributes to the improvement of the efficiency.
We accomplished block shaped light trapping structure for the first time by wet etching of the glass substrate, which enables the high efficiency thin film solar cell with the aid of the good step coverage deposition.
