量子点敏化太阳能电池（QDSSC）在过去几年中经历了持续的性能增长，表现出> 13%的光电转换效率。QDSSC构成了利用半导体量子点（QD）的性质的智能方法，减轻了输运约束。与其他QD太阳能电池配置相比，对于QDSSC，记录效率已经用无Pb和Cd的敏化剂报道。为了提供具有非常高的QD负载的光阳极的技术开发和新电解质的发现，包括所有固体配置，是该技术必须解决的最重要的未来挑战，以进一步提高电池性能和稳定性。
Quantum dot sensitized solar cells (QDSSCs) have experienced a continuous performance growth in the past years presenting a photoconversion efficiency >13%. QDSSCs constitute a smart approach to take advantage of the properties of semiconductor quantum dots (QDs), mitigating the transport constrains. In contrast with other QD solar cell configurations, for QDSSCs, the record efficiencies have been reported with Pb and Cd‐free based sensitizers. The development of techniques in order to provide photoanodes with very high QD loading and the discovery of new electrolytes, including all solid configurations, are the most important future challenges that this technology must address to further increase cell performance and stability.
