Provisional Patent Application Filed

APPLICATIONS:

This is a novel innovation applicable to the high-efficiency solar cell market.

PROBLEMS ADDRESSED:

This innovation is designed to improve the market share for high-efficiency solar cells with a low development and market cost with comparable efficiency in comparison to high-efficiency solar cells currently on the market.

BENEFITS:

  • Low processing cost
  • High efficiency
  • Decreased CAPEX (capital expenditure) and OPEX (operational expenditure) costs.
  • Low temperature processing with higher yield

TECHNOLOGY DESCRIPTION:

This is a technological method involving photoinitiators and a passivated interface of organic molecules. The interface is designed to coat silicon wafers and change the electronic structure at the surface to ultimately allow electrons or holes to transport across the organic layer to a conducting layer. When exposed to light and radiation of a specific range of energy, the photoinitiators are able to react with the silicon surface, consequently.

STAGE OF DEVELOPMENT:

Prototype development and testing are underway along with ongoing research.
