Tandem solar cells target higher output as commercialization nears

01The Story新闻事实

Tandem solar panels combine silicon with a second light-absorbing layer, often perovskite, to capture more of the sunlight spectrum. The technology could produce roughly 25 percent more electricity than many panels sold today, while recent efficiency records and early commercial shipments suggest progress. Costs, durability and competition from Chinese manufacturers remain important barriers to wider adoption.叠层太阳能电池将硅与通常为钙钛矿的第二层吸光材料结合，以捕获更广泛的太阳光谱。该技术的发电量可能比目前销售的许多面板高约25%，近期效率纪录和早期商业出货显示其正在推进。不过，成本、耐久性以及来自中国制造商的竞争仍是扩大应用的重要障碍。

Tandem panels could produce roughly 25 percent more electricity than many panels sold today.叠层面板的发电量可能比目前销售的许多面板高约25%。
LONGi reported a certified efficiency of 35.5 percent for a perovskite-silicon tandem cell and 31.4 percent for a tandem module.LONGi报告称，其钙钛矿-硅叠层电池的经认证效率达到35.5%，叠层组件效率达到31.4%。
The best conventional silicon cells convert roughly 27 percent of incoming sunlight into electricity, near a theoretical limit of 29 percent.最好的传统硅电池可将约27%的入射阳光转化为电力，接近29%的理论上限。
Tandem devices use a top perovskite layer to capture higher-energy light and a silicon layer underneath to collect much of the lower-energy light that passes through.叠层设备利用顶部钙钛矿层捕获高能光，并由下方硅层收集穿透的较低能量光。
Oxford PV announced the first commercial shipment of perovskite-silicon tandem panels to a U.S. customer in 2024.Oxford PV于2024年宣布向一名美国客户完成首批钙钛矿-硅叠层面板商业出货。

Tandem cells could increase solar output from existing land and rooftop areas, but their market impact depends on cost and long-term durability.叠层电池有望在不增加土地和屋顶面积的情况下提高太阳能产出，但其市场影响取决于成本和长期耐久性。

Cause因果关系

How the design captures more light这种设计如何捕获更多光线

Silicon does not efficiently harvest every part of sunlight’s spectrum. A second material can absorb wavelengths that silicon handles less effectively, allowing the two layers to divide the available light.硅无法高效利用太阳光谱中的所有部分。第二种材料可以吸收硅处理效率较低的波长，使两层材料能够分担可利用的光线。

The upper perovskite layer can capture higher-energy light, while the silicon layer collects much of the lower-energy light that passes through.上方的钙钛矿层可捕获高能光，下方的硅层则收集大部分穿透的低能量光。
Higher-energy photons can lose excess energy as heat in silicon, while some lower-energy photons pass through without being captured.在硅材料中，高能光子可能以热量形式损失多余能量，而部分低能光子会穿透而未被捕获。

Future signal前瞻信号

From laboratory results to the market从实验室成果走向市场

The technology has begun moving toward commercial use, but cost was a major reason it had not gained market share. Oxford PV’s shipment indicates early market entry, while the source notes that durability remains an unresolved condition.这项技术已开始走向商业应用，但成本曾是其未能获得市场份额的主要原因。Oxford PV的出货表明其已初步进入市场，而报道指出耐久性仍是尚未解决的条件。
