Alta Devices制造了一种薄膜单结GaAs组件，在一个太阳强度下，在全球AM1.5光谱下，独立确认的太阳能转换效率为23.5%。这代表着在非集中阳光下的陆地模块的新纪录。减少阴影、固有的电气互连、优化的光耦合和高效的太阳能电池都有助于该模块无与伦比的性能。在这些属性的背后是Alta太阳能材料的薄而灵活的性质，这使得电池和模块级别的转换效率很高。由于其薄膜特性，这种组件技术具有降低太阳能发电成本的潜力，超过电网平价。灵活的外形和户外环境中的高性能的独特组合使这项技术在传统太阳能安装以及各种先进的光伏(PV)应用中都具有极强的竞争力。
Alta Devices has fabricated a thin-film single-junction GaAs module with an independently confirmed solar energy conversion efficiency of 23.5%, under the global AM1.5 spectrum at one sun intensity. This represents a new record for terrestrial modules under non-concentrated sunlight. Reduced shading, intrinsic electrical interconnect, optimized optical coupling, and high efficiency solar cells all contributed to the unmatched performance of this module. Behind these attributes lies the thin and flexible nature of Alta's solar material, which enables high conversion efficiency at the cell and module levels. Because of its thin-film characteristics, this module technology has the potential to reduce the cost of solar energy generation beyond grid parity. The unique combination of a flexible form factor and high performance in outdoor environments makes this technology extremely competitive for both traditional solar installations as well as a variety of advanced photovoltaic (PV) applications.
