Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a double-sided solar cell that uses metal oxide nanorods in its active layer. These nanorods are shaped to narrow towards one side, efficiently connecting between two transparent conducting layers. The unique configuration allows the solar cell to absorb light from both sides and potentially improves electrical contact efficiency.

Use CasesContent extracted from patent full text and abstract with AI.

  • Building-integrated photovoltaics with transparent surfaces, such as solar windows or glass facades
  • Solar panels for vehicles where both surfaces may be exposed to sunlight
  • Portable solar devices that can collect energy from multiple directions
  • Agricultural greenhouses with transparent solar panels to generate energy while allowing light for plants

BenefitsContent extracted from patent full text and abstract with AI.

  • Increased energy generation by absorbing light from both sides
  • Potential higher efficiency due to improved electrical contacts with nanorods
  • Enhanced transparency, enabling integration into windows and glass surfaces
  • Flexible design suitable for various functional and aesthetic applications

Patent Abstract

Zweiseitige Solarzelle, mindestens aufweisend ein transparentes Substrat, auf dem eine TCO-Schicht als erster Kontakt angeordnet ist, auf dem sich eine aktive Schicht befindet, die mit einer weiteren TCO-Schicht als zweiter Kontakt versehen ist, dadurch gekennzeichnet, dass in der aktiven Schicht (4) Metalloxid-Nanostäbe (3) mit in Richtung zweiten Kontakt (5) sich verjüngendem Querschnitt angeordnet sind, wobei die Grundfläche der Metalloxid-Nanostäbe (3) mit dem größeren Querschnitt direkt am ersten Kontakt (2) anliegt, und die aktive Schicht (4) wie eine Matrix die Metalloxid-Nanostäbe (3) vollständig in ihrer Höhe bedeckt, wobei die Spitzen der Metalloxid-Nanostäbe (3) Punktkontakte bilden.
