Modeling and comparison of bulk and thin-film luminescent solar concentrators based on colloidal perovskite quantum dots

Zida Zheng et al.

Summary: This Letter demonstrates and develops a Monte Carlo ray-tracing model and a numerical description for the performance and loss evaluation of photovoltaic integrated luminescent solar concentrators (LSCs) based on colloidal quantum dots. The study finds that large-area thin-film LSCs generally perform better than bulk LSCs due to the suppression of scattering and the retention of quantum yield.

Large-Area Transparent Quantum Dot Glass for Building-Integrated Photovoltaics

Jing Huang et al.

Summary: A concept of transparent quantum dot glass (TQDG) is proposed for building-integrated photovoltaics (BIPVs). TQDGs, serving as both power-generating components and building construction materials, demonstrate favorable photovoltaic, aesthetic, and building envelope characteristics. They also have better thermal and sound insulation properties compared to normal float glass, as well as improved mechanical performance and safety.
