Highly efficient dye-sensitized solar cells achieved by matching

A good match of energy levels between dyes and redox couples is an important factor to reduce energy loss and further improve the power conversion efficiency of dye-sensitized solar cells (DSSCs). Pseudohalogens were introduced as an improved alternative to iodide/triiodide (I − /I 3−) couples to achieve this goal.

Rational selection of light sources for LED-based solar simulators

We reveal new ways to configure LED-based solar simulators with just four light source types to achieve A+ class spectrum. Even with A+ class spectrum significant spectral mismatch effects can remain, but may be reduced by adding or adjusting light sources.

Efficient Ternary Organic Solar Cells with Suppressed Nonradiative

3 天之前· Organic solar cells (OSCs) have developed rapidly in recent years. However, the energy loss (Eloss) remains a major obstacle to further improving the photovoltaic performance. To address this issue, a ternary strategy has been employed to precisely tune the Eloss and boost the efficiency of OSCs. The B‒N-based polymer donor has been proved process high E(T1)
