An Investigation on a Crystalline-Silicon Solar Cell with Black Silicon Layer at the Rear

Crystalline-Si (c-Si) solar cell with black Si (b-Si) layer at the rear was studied in order to develop c-Si solar cell with sub-band gap photovoltaic response. The b-Si was made by chemical etching. The c-Si solar cell with b-Si at the rear was found to perform far better than that of similar structure but with no b-Si at the rear, with the efficiency being increased relatively by 27.7%. This finding was interesting as b-Si had a large specific surface area, which could cause high surface recombination and degradation of solar cell performance. A graded band gap was found to form at the rear of the c-Si solar cell with b-Si layer at the rear. This graded band gap tended to expel free electrons away from the rear, thus reducing the probability of electron-hole recombination at b-Si and improving the performance of c-Si solar cell.

Performance Analysis of an HJ-IBC Silicon Solar Cell in Ultra-High Temperatures: Possibility of Lower Reduction Efficiency Rate

The paper investigates the influence of various geometrical parameters (thickness of intrinsic a-Si, gap distance, n-type and p-type stripes) and the temperature on the performance of heterojunction interdigitated back contact (HJ-IBC) solar cell. There exists a strong correlation between the gap distance and the width of the n-type or p-type of the amorphous silicon (a-Si) layer as well as the thickness of the a-Si layer and the performance of the HJ-IBC silicon solar cells. It is shown that the defined reduction efficiency rate of an HJ-IBC silicon solar cell is lower than the reduction efficiency rate of conventional silicon solar, suggesting a better performance in the outdoor condition of the HJ-IBC solar cells. It is also argued that a temperature-dependent free HJ-IBC solar cell can be realized by tuning the intrinsic layer thickness. Furthermore, the comparison between top/rear contact HJ and HJ-IBC solar cell shows that HJ-IBC has the best performance in outdoor condition.

     

Effects of Annealing Conditions of Electrodes on the Photovoltaic Properties of Sintered Cadmium Sulfide/Cadmium Telluride Solar Cells

Polycrystalline n -CdS/ p -CdTe solar cells with a commerical carbon paint on the p -CdTe layer and an In-Ag paint on the n -CdS layer were fabricated by a coating and sintering method. Electrical properties of the conducting paints and solar cell parameters of the heterojunction solar cells were investigated as a function of electrode annealing conditions. The sintered CdS/CdTe solar cells whose electrode contacts were annealed at 350°C for 10 min in nitrogen showed maximum values of short-circuit current density, fill factor, and solar efficiency. Commercial carbon and silver paints can be used as electrodes to fabricate sintered CdS/CdTe solar cells with efficiency over 10%.

High-efficiency GaAs and GaInP solar cells grown by all solid-state molecular-beam-epitaxy

We report the initial results of GaAs and GaInP solar cells grown by all solid-state molecular-beam-epitaxy (MBE) technique. For GaAs single-junction solar cell, with the application of AlInP as the window layer and GaInP as the back surface field layer, the photovoltaic conversion efficiency of 26% at one sun concentration and air mass 1.5 global (AM1.5G) is realized. The efficiency of 16.4% is also reached for GaInP solar cell. Our results demonstrate that the MBE-grown phosphide-contained III-V compound semiconductor solar cell can be quite comparable to the metal-organic-chemical-vapor-deposition-grown high-efficiency solar cell.

Efficiency improvement of silicon solar cells enabled by ZnO nanowhisker array coating

An efficient antireflection coating is critical for the improvement of silicon solar cell performance via increased light coupling. Here, we have grown well-aligned ZnO nanowhisker (NW) arrays on Czochralski silicon solar cells by a seeding-growth two-step process. It is found that the ZnO NWs have a great effect on the macroscopic antireflection effect and, therefore, improves the solar cell performance. The ZnO NW array-coated solar cells display a broadband reflection suppression from 500 to 1,100 nm, and the minimum reflectance smaller than 3% can easily be achieved. By optimizing the time of ZnO NW growth, it has been confirmed that an increase of 3% relatively in the solar cell efficiency can be obtained. These results are quite interesting for the application of ZnO nanostructure in the fabrication of high-efficiency silicon solar cells.
