Method for the Production and Series Connection of Strip-Shaped Elements on a Substrate

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention discloses a method for manufacturing and series-connecting strip-shaped elements (such as photovoltaic cells) on a substrate. The method enables a much denser arrangement by using small, region-specific openings and specialized structuring of contact layers, effectively reducing the unused area between elements and increasing the active surface area available for energy conversion. The process particularly suits solar cell modules, leading to higher efficiency by minimizing the space required for electrical isolation and interconnection.

Use CasesContent extracted from patent full text and abstract with AI.

• Manufacturing of high-efficiency thin-film solar cell modules for use in solar panels.
• Production of other semiconductor-based strip devices requiring compact series connection, such as sensors or light emitters.
• Integration into flexible or lightweight photovoltaic modules for building-integrated photovoltaics (BIPV).
• Advanced manufacturing for compact, modular electronic devices that benefit from efficient space utilization.

BenefitsContent extracted from patent full text and abstract with AI.

• Increases the proportion of active surface area in solar modules, enabling energy conversion rates above 98%.
• Reduces losses associated with intercellular connections and isolation, resulting in higher overall module efficiency.
• Enables more compact module designs, potentially lowering production costs or allowing greater energy output in the same area.
• Provides flexibility in material choice and processing method (laser ablation, etching, PVD, CVD), supporting various manufacturing environments.
• Improves yield by minimizing inactive regions and optimizing interconnections, especially useful for large-scale solar panel production.
