技术领域technical field
本发明涉及太阳能领域，具体而言，涉及一种可弯曲单晶硅太阳能发电装置。The invention relates to the field of solar energy, in particular to a bendable single crystal silicon solar power generation device.
背景技术Background technique
当前，以化石燃料为主导的国际能源形势，存在着对地区气候条件的影响、环境的恶化、燃料资源枯竭以及能源安全等威胁。因此，采用清洁、安全、无枯竭隐患的可再生能源对未来全球可持续发展是必不可少的。21世纪以来，由于在世界范围内的社会认知度提高，以及近十几年在技术上的创新和突破，自然可利用的太阳能显示出了想满足未来世界能源需求的明显优势。根据发电方式的不同太阳能光伏可分为光伏发电系统和光热发电系统。随着光伏发电组件的成本降低和效率的提高，分布式光伏发电正成为我国重点鼓励发展和精准脱贫攻坚的战略方向，而柔性化、轻薄化和光伏建筑一体化是分布式光伏发电的发展方向，此外该技术还广泛应用于便携式移动电源及军工领域。At present, the international energy situation dominated by fossil fuels poses threats to regional climate conditions, environmental degradation, depletion of fuel resources, and energy security. Therefore, the use of clean, safe, and non-exhaustive renewable energy is essential for future global sustainable development. Since the 21st century, due to the increase in social awareness around the world, as well as technological innovation and breakthroughs in the past ten years, naturally available solar energy has shown obvious advantages in meeting the future energy needs of the world. According to different power generation methods, solar photovoltaic can be divided into photovoltaic power generation system and photothermal power generation system. With the cost reduction and efficiency improvement of photovoltaic power generation components, distributed photovoltaic power generation is becoming a strategic direction for my country to encourage development and precise poverty alleviation, while flexibility, lightness and photovoltaic building integration are the development directions of distributed photovoltaic power generation , In addition, this technology is also widely used in portable mobile power and military fields.
目前，传统的太阳能电池板采用玻璃、塑料等刚性材料作为基底，不仅容易受到冰雹、石头等重物砸毁损坏，而且体积庞大、厚重难支撑、不可弯曲、不可携带，特别不适于布置在屋顶、遮阳及可移动设备等未来分布式光伏发电要求，其广泛应用受到限制。传统发电材料中只有非晶硅才能实现弯折，但是非晶硅的光电转换效率比较低，效益不高。因此针对分布式能源的发展急需具柔性且可以弯曲的晶硅太阳能电池组件光伏发电系统。At present, traditional solar panels use rigid materials such as glass and plastic as substrates, which are not only easily damaged by heavy objects such as hailstones and stones, but also bulky, heavy and difficult to support, inflexible, and non-portable, especially not suitable for placement on the roof Future distributed photovoltaic power generation requirements such as solar shading and mobile equipment limit its wide application. Among the traditional power generation materials, only amorphous silicon can be bent, but the photoelectric conversion efficiency of amorphous silicon is relatively low, and the benefit is not high. Therefore, a flexible and bendable crystalline silicon solar cell module photovoltaic power generation system is urgently needed for the development of distributed energy.
