This paper reports on the rst use of two-dimensional (2D) device simulation for optimising the frontnger spacing of one-sun high-e ciency silicon solar cells of practical dimensions. We examine the 2D current ow patterns in these devices under various illumination conditions, resulting in improved insight into the operating conditions of the cells. Results for the optimal spacing of the front m...

Vertically aligned silicon nanowires have been synthesized by the chemical etching of silicon wafers. The influence of a hydrogenated amorphous silicon (a-Si:H) layer (shell) on top of a silicon nanowire (SiNW) solar cell has been investigated. The optical properties of a-Si:H/SiNWs and SiNWs are examined in terms of optical reflection and absorption properties. In the presence of the a-Si:H sh...

Solar energy is a pure and reproducible energy. China has paid more consideration to the investigation employment of solar The focuses on phenomenon PID capability degradation inactivation mediums for instance alumina/silicon nitride in transparent silicon high-efficiency cells. Through laboratorial effect individual in-activation membrane processes damping behavior, it found that deposition ap...

Roll-to-roll processing of thin film solar cells on flexible low cost substrates is an attractive option to lower the production cost of photovoltaic modules. Plastic substrates like PET or PEN are insulating which potentially offers advantages compared to conducting steel foils. However, plastic substrates require lower processing temperatures and novel schemes for efficient light trapping. In...

Thin-film solar cells have the potential to significantly decrease the cost of photovoltaics. Light trapping is particularly critical in such thin-film crystalline silicon solar cells in order to increase light absorption and hence cell efficiency. In this article we investigate the suitability of localized surface plasmons on silver nanoparticles for enhancing the absorbance of silicon solar c...

Silicon solar cells based on high temperature passivating contacts are becoming mainstream in the photovoltaic industry. Here, we developed a high-quality boron-doped poly-silicon hole contact. When combined with co-processed...

The p-type crystalline silicon wafers have occupied most of the solar cell market today. However, modules made with n-type crystalline silicon wafers are actually the most efficient modules up to date. This is because the material properties offered by n-type crystalline silicon substrates are suitable for higher efficiencies. Properties such as the absence of boron-oxygen related defects and a...
