Tandem Solar Cell—Concept and Practice in Organic Solar Cells

2015
In the past decade, organic solar cell (OPV) technology has been intensively studied and improved significantly due to its attractive properties in manufacturability, flexibility, light weight etc. The power conversion efficiency (PCE) has been enhanced dramatically from ~2–3 to ~12 % through materials, interface and device architecture innovations ...

Photon tunneling in tandem solar cells

2015 IEEE 42nd Photovoltaic Specialist Conference (PVSC), 2015
We investigate the influence of surface texture on the effectiveness of reflectance by intermediate reflectors in thin-film tandem solar cells. Two distinct angular reflection regimes are identified. For large-angle textures, frustrated total internal reflection or photon tunneling is the dominating mechanism.

Introduction to Tandem Solar Cells

2022
Photovoltaics has today become a mature industry and one of the main reasons of the tremendous growth in recent years is the continuous improvement in the performance and lifetime of PV modules. However, one of the main limitations in the improvement of the performance of commercialized PV devices is that the efficiency is getting closer and closer to ...

Tandem Organic Solar Cells with 21.5% Efficiency

Advanced Materials
Abstract Tandem organic solar cells (OSCs) offer a promising strategy for enhancing light utilization and reducing energy loss, presenting significant potential in achieving high power conversion efficiency (PCE). Herein, a narrow bandgap acceptor, BTA‐4F, featuring a 2‐methyl‐2H‐benzotriazole (BTA) central core, is fabricated, which ...

Approaches for III‐V/Si tandem solar cells and comparative studies on Si tandem solar cells

Progress in Photovoltaics: Research and Applications
AbstractPhotovoltaic (PV)‐powered vehicle applications are very attractive for reducing CO2 emission and creation of new market. Development of Si tandem solar cells is very promising for high‐efficiency and low‐cost solar cells. This paper presents our approaches for III–V/Si 3‐junction tandem solar cells.

Power Matching of Tandem Solar Cells

2011
We show that the usual current matching condition for tandem solar cells is insufficient because the matching of the subcell currents minimizes the fill factor of the device. We introduce a new definition for the matching condition of tandem solar cells, i.e.
