Polythiophene derivatives synthesized by Kumada catalyst-transfer polycondensation (KCTP) have been intensively studied as potential candidates for low-cost organic solar cells (OSCs) due to their capability of scalable production. However, the power conversion efficiency (PCE) is still unsatisfactory so far
Infrared (IR) solar cells are promising devices for improving the power conversion efficiency (PCE) of conventional solar cells by expanding the utilization region of the sunlight spectrum to near-infrared range. IR solar cells based on colloidal quantum dots (QDs) have attracted extensive attention due to the widely tunable absorption …

In this work we describe the dependence of luminescent coupling efficiency on the bias-voltage in multijunction solar cells. We combine a theoretical derivation and Sentaurus simulations to show that the luminescent coupling efficiency has a significant dependence on the bias voltage, and such dependence is mainly due to the change in the ratio …
Modern silicon solar cell concepts with passivated emitter rear contact (PERx), heterojunction (SHJ), or integrated back contact (IBC) enable bifacial solar cell operation at low additional cost. Due to these reasons, the International Technology Roadmap for Photovoltaics predicts nearly 70% market share for bifacial solar cells in 2030.
