Efficient electron selective contacts, smoother rear silicon surface and passivation of silicon-electrode interfaces could reduce parasitic light absorption and electron-hole recombination. Therefore, they are necessary for high conversion efficiency in silicon solar cells. In this work, a novel transition metal doped glass frit is fabricated and introduced into pristine Al paste. As a result, the average power conversion efficiency (PCE) of cells is improved from 17.9 to 18.3%. Combining several results, the improvement can be attributed to three key factors: (a) a thicker back surface field (BSF) layer that blocks electrons; (b) a smoother rear silicon surface which leads to less parasitic absorption; and (c) glass frit coating on aluminum particles which may facilite hole-transfer from silicon layer to aluminum electrode.

AbstractThe present research is focused on developing ZnAl2O4 (gahnite) spinel as an antireflection coating material for enhanced energy conversion of polycrystalline silicon solar cells (PSSC). ZnAl2O4 has been synthesized using dual precursors, namely aluminum nitrate nonahydrate and zinc nitrate hexahydrate in ethanol media. Diethanolamine has been used as a sol stabilizer in sol-gel process for ZnAl2O4 nanosheet fabrication. ZnAl2O4 nanosheet was deposited layer-by-layer (LBL) on PSSC by spin coating method. The effect of ZnAl2O4 coating on the physical, electrical, optical properties and temperature distribution in PSSC was investigated. The synthesized antireflection coating (ARC) material bears gahnite (ZnAl2O4) spinel crystal structure composed of two dimensional (2D) nanosheets. An increase in layer thickness proves the LBL deposition of ARC on the PSSC substrate. The ZnAl2O4 2D nanosheet comprising ARC on the PSSC was tested and it exhibited a maximum of 93 % transmittance, short-circuit photocurrent of 42.364 mA/cm2 and maximum power conversion efficiency (PCE) 23.42 % at a low cell temperature (50.2 °C) for three-layer ARC, while the reference cell exhibited 33.518 mA/cm2, 15.74 % and 59.1 °C, respectively. Based on the results, ZnAl2O4 2D nanosheets have been proven as an appropriate ARC material for increasing the PCE of PSSC.

When the petrochemical raw materials continue to rise, resulting in the demand for solar power to increase 25-30% annually. So solar power is currently the most practical and efficient best alternative energy sources. silicon solar cells is now the main raw material, which can be divided into: single-crystal silicon, polycrystalline silicon and amorphous silicon. The most efficiency is single crystal silicon solar cells, polycrystalline silicon solar cells yield larger and more expensive, amorphous silicon solar cell has the lowest price but the worst efficiency. Solar module packaging can produce the required voltage and current, and blocking the water to increase product life. Because the color of solar cells are usually black, is not easy to integrate into the environment. If we can use color packaging material to make solar modules, will be applied to toys, gifts, landscape, lighting and other everyday products, resulting in a more perfect match. This article will explore a range of color package parameters and the relative conversion efficiency of solar cell modules.
