贺利氏、帝科、匡宇、Kyoto Elex、乐叶、尚德、腾晖、正泰等邀您3月29日齐聚无锡，探讨太阳电池浆料与金属化技术

金属化是晶硅太阳电池生产的关键步骤，通过导电浆料丝网印刷和烧结等手段，在硅片正面和背面制备金属化电极，从而将光生载流子导出电池。浆料是金属化工艺的关键材料，约占电池片非硅成本的50-60%。浆料由导电相、粘结剂和有机载体等组成，包括正面银浆、背面银浆和背面铝浆，对电池的光电转换效率和成本有重要影响。

2017年中国光伏行业保持高速增长，全年新增装机超过50GW，极大地促进了上游导电浆料行业的发展。与此同时，由于持续的效率提升需求和成本降低压力，晶硅太阳电池技术快速更新迭代，对金属化工艺及导电浆料不断提出更高的要求。

PERC电池要求浆料具有较宽的烧结工艺窗口，降低烧结温度以避免LID；PERC背银要不能烧穿背钝化层并有良好的拉力表现，以及良好地匹配PERC铝浆。双面PERC在减少铝浆用量的同时，要求提升铝栅线高宽比并降低体电阻率。黑硅电池表面特殊的纳米结构，需求高拉力并且可以平衡接触电阻和开路电压的正银。异质结电池需要用低温银浆，并且最好可以在室温下储存。N型双面电池则迫切需要降低银浆消耗量以控制成本。

“十三五”太阳能发展规划提出，到2020年光伏发电要实现用电侧平价上网。减少电池片浆料用量，和硅片的价格下降一起构成电池成本降低的主要驱动力。多主栅、超细栅线金属化技术有利于减少正银用量；正银国产化率的提升，也有利于电池企业降低浆料成本。此外，2018年随着双面PERC电池、黑硅电池、N型双面电池和异质结电池的放量，相应的银浆产品预计将批量出货。

第四届太阳电池浆料与金属化技术论坛将于2018年3月29日在江苏无锡召开。会议将探讨全球与中国光伏行业展望与浆料市场前景，太阳电池金属化技术趋势，用于新型高效电池的浆料研发与应用，正面银浆国产化与成本降低路径，银浆和铝浆技术进展与投资机遇，光伏浆料关键原料生产与供需等。

Heraeus, DKEM, Transcom,  Kyoto Elex, Longi Solar, Suntech, Talesun  Chint invite you to join in Wuxi on March 29, to discuss solar cell paste  metallization technologies

Metallization is the key step in the production of crystalline silicon solar cells. The photogenerated carriers are led out of the cell by preparing metalized electrodes on the front the back of the silicon wafer by screen printing sintering of conductive paste. Solar cell paste is the key material for metallization, accounting for about 50-60% of the non-silicon cost of cells. The paste is made up of conductive phase, binder organic carrier, includes front-side silver paste, rear-side silver paste  rear-side aluminum paste, has an important influence on the cell’s photoelectric conversion efficiency cost.

In 2017, China''s PV industry maintained its rapid growth with an annual installed capacity of more than 50GW, greatly boosting the development of upstream conductive paste industry. At the same time, crystalline silicon solar cell technologies have rapidly been updated due to the continuous dem for efficiency improvement pressure to reduce costs, which put forward higher requirements for metallization process paste.

PERC solar cell requires that paste has a wide sintering process window, lower sintering temperature to avoid LID; PERC rear-side silver paste should not burn through the back-passivation layer, has good tension performance well match PERC aluminum paste. While reducing the consumption of aluminum paste, bifacial PERC requires increasing the aspect ratio of the aluminum grid line  lowering the volume resistivity. Black silicon cell surface has special nanostructures, deming silver paste has high tension  can balance contact resistance open circuit voltage. Heterojunction cell requires low temperature silver paste preferably stored at room temperature. N-type bifacial cell urgently needs to reduce the consumption of silver paste to control cost.

National “13^th FYP” PV industrial plan proposed that by 2020 PV power generation to achieve grid parity. Reducing the consumption of per cell paste, along with the falling price of silicon wafer, are the main driving force to reduce the cell cost. MBB, ultra-fineline metallization technologies help to reduce the consumption of silver paste; increasing localization rate of front-side silver pastes help cell manufactures to reduce paste cost. In addition, with the mass production of bifacial PERC cells, black silicon cells, n-type bifacial cells heterojunction cells, the corresponding silver pastes are expected to be shipped in volume in 2018.

4^th Solar Cell Paste Metallization Forum will be organized by ASIACHEM on 29 Mar.2018 in Wuxi, Jiangsu, China. The upcoming conference will discuss the global China’s PV industry outlook  paste market prospect; solar cell metallization technology trends; R&D application of pastes for advanced high efficiency solar cells; front-side silver pastes localization trends  cost reduction; silver paste aluminum paste technical progress investment opportunities; key raw materials production, supply dem of solar cell pastes, etc.

The topics are as follows:

1. Global China’s PV industry outlook paste market prospect

2. Advanced paste technologies for PERC, HJT  N-type bifacial cells

3. MBB cell metallization solutions ultra-fineline pastes

4. Knotless screen technology supporting pastes

5. R&D application of front-side silver paste for black silicon cell

6. Screen printing technology improvements yield enhancement - double printing dual printing

7. Ag paste Al paste localization trends investment opportunities
