The expectation to progress towards Terawatts production by solar technologies requires continuous development of new materials to improve efficiency and lower the cost of devices beyond what is currently available at industrial level. At the same time, the turnaround time to make the investment worthwhile is progressively shrinking. Whereas traditional absorbers have developed in a timeframe spanning decades, there is an expectation that emerging materials will be converted into industrially relevant reality in a much shorter timeframe. Thus, it becomes necessary to develop new approaches and techniques that could accelerate decision-making steps on whether further research on a material is worth pursuing or not. In this review, we will provide an overview of the photoemission characterization methods and theoretical approaches that have been developed in the past decades to accelerate the transfer of emerging solar absorbers into efficient devices.

通过太阳能技术实现太瓦生产的期望需要不断开发新材料，以提高效率并降低设备成本，超出目前工业水平。与此同时，使投资物有所值的周转时间正在逐渐缩短。传统吸收器的发展时间跨度跨越数十年，而新兴材料有望在更短的时间内转化为与工业相关的现实。因此，有必要开发新的方法和技术，以加快对材料的进一步研究是否值得进行的决策步骤。在这次审查中，
