光伏组件新技术的研发与应用可以有效提升光伏系统发电效率与可靠性，降低度电成本。双玻组件、叠片组件和半片电池组件是目前最具代表性的组件新技术。为了实现平价上网的终极目标，光伏行业要求组件持续提高性能并降低成本，驱动组件新技术的应用并走向成熟。

双玻组件以光伏玻璃代替背板，具有更高的可靠性、耐候性、耐磨性、绝缘性和防火等级，更低的衰减，以及生命周期更高的发电量。此外，双玻组件在双面发电、农业光伏和1500V系统应用相比传统组件也更具优势。随着双玻组件重量、抗风压、良品率和漏光等问题逐步得到解决，2016年双玻组件在中国市场的应用已超过2GW。

叠片组件将光伏电池以串并联结构紧密排布，几乎不需要焊带，同样的组件面积内可以放置多于常规组件13%以上的电池片。因此叠片组件具有输出功率高、内部损耗低、反向电流热斑效应小等优势。叠片组件技术的关键是电池联接的可靠性。中国光伏行业积极推进叠片组件的技术研发与大规模制造，赛拉弗于2016年3月推出日食系列组件，2017年2月，东方环晟宣布建设5GW叠片组件产能。

半片电池组件将一般的电池对切后串联起来，电池片电流失配损失减小，且电流在组件内部的自身损耗减少，因此半片电池组件的输出功率比同版型整片电池组件高约10W，而且热斑温度比同版型整片电池组件的温度低约25℃。中节能、协鑫、REC Solar、海润、航天机电等企业已开始量产高功率半片电池组件。

2017双玻、叠片与半片电池组件论坛将于7月25日在无锡召开。会议将探讨全球与中国光伏市场展望与组件技术发展趋势，双玻、叠片与半片电池组件技术优势与投资回报，双玻组件制造工艺优化及封装材料选择，叠片组件封装技术与工业化生产前景，半片电池组件大规模生产的良品率控制等。

Background

PV module new technologies R&D and application can effectively enhance the power generation efficiency and reliability, and reduce the levelized cost of electricity (LCOE). Double glass, overlapped-cell & halfcut-cell modules are the most representative new technologies. In order to achieve the ultimate goal of grid parity, PV industry requires modules to continuously improve performance and reduce costs, drive the mature application of new technology modules.

Double glass module replaces the PV backsheet with glass, which has higher reliability, weatherability, abrasion resistance, insulation and fire rating, lower attenuation, and higher lifecycle generating capacity. In addition, double glass modules also have more advantages in the bifacial power generation, agricultural PV and 1500V system applications compared with traditional modules. With the solutions of double glass module’s weight, wind load resistance, yield and light leakage, the application of China’s double glass modules has more than 2GW in 2016.

Overlapped-cell module places the solar cells in a serial-parallel structure, with little or no need for welding belt. More than 13% solar cells can be placed in the same module area. So overlapped-cell module has advantages of high output power, low internal loss and low reverse current hot spot effect. The key of overlapped-cell module technology is the reliability of cell connections. China's PV industry is actively promoting the technology R&D and mass production of overlapped-cell modules. Seraphim launched “Eclipse” series modules in Mar. 2016. DZS Solar announced the construction of 5GW overlapped-cell modules in Feb. 2017.

Halfcut-cell module connect the halfcut-cells in series, reducing the cell current mismatch loss and the module internal current loss, so that output power of halfcut-cell module is higher about 10W than the same type full-cell module, and the hot spot temperature is lower about 25℃ than the same type full-cell module. CECEP, GCL, REC Solar, Hareon Solar, HT-SAAE, etc. have begun mass production of high power half-cell modules.

Double Glass, Overlapped-cell & Halfcut-cell Modules Forum 2017 will be held on 25 July in Wuxi, Jiangs, China. The upcoming conference will discuss global and China’s PV market outlook and module technology trends, technical advantages and investment returns of double glass, overlapped-cell & halfcut-cell modules, double glass modules manufacturing process optimization and encapsulation materials selection, overlapped-cell module encapsulation technology and industrial production prospect, yield control of halfcut-cell modules mass production.
