The remarkable advances over the past few years in performance of photovoltaic cells, including the advent of new absorber materials, call for an update to the previous assessment of prospects for future progress. The same simple criteria with some refinements, based on cell and module performance data, serve to evaluate and compare most types of solar cells. Apart from Si and InP, for all types the "best cells" have improved in conversion performances (and crystalline Si modules have made major strides in cost reduction). New cell types, such as "perovskite", sustainable chalcogenide, and quantum dot cells, are included. CdTe results bring those cells in line with other well-developed ones, lending some credence to the idea that the criteria provide the reader with knowledge, useful for gauging possible future technological developments. Additionally, the developments of the past few years show that, while the advent of more new cell types cannot be predicted, it can be aided and stimulated by innovative, daring, and creative new materials research.
在过去几年中，光伏电池的性能取得了显著的进步，包括新型吸收材料的出现，这要求对未来发展前景的先前评估进行更新。基于电池和模块性能数据的一些改进的相同简单标准，可用于评估和比较大多数类型的太阳能电池。除了 Si 和 InP，对于所有类型，“最佳电池”在转换性能方面都有所提高（晶体硅模块在降低成本方面取得了重大进展）。包括新型电池类型，如“钙钛矿”、可持续硫属化物和量子点电池。CdTe 的结果使这些电池与其他成熟的电池保持一致，这使得人们相信这些标准为读者提供了有用的知识，有助于衡量未来可能的技术发展。此外，过去几年的发展表明，虽然无法预测更多新型电池类型的出现，但通过创新、大胆和创造性的新材料研究，可以帮助和刺激它们的出现。
