Advanced crystalline silicon solar cell designs

Objective



1. Objectives

The objective of this project is: the development of at least one advanced, crystalline silicon solar cell technology with the following characteristics: - better commercialisation aspects than the standard technology. a design that can be easily used on larger substrates for large scale power production higher efficiencies than standard crystalline silicon solar cells made by the most comparable technology.

2. Technical approach

The project is divided in three parts. First the different solar cell designs are discussed and simulated by computer programmes. The common problems like increased recombination, shunting as well as series resistance are examined. In the second phase the solar cells must be produced according to the cell designs as defined in phase one. The cell process parameters must be optimised to testify the potential of the designs. In a third phase concepts will be developed to improve laboratory-scale methods to a large-scale production level and a complete technology from starting material up to module design will be worked out.

3. Expected achievements and exploitation

The result will be an improved crystalline silicon solar cell technology with the following characteristics. It will be an all back-contact cell with improved efficiency and cost/Wp compared to 'standard' crystalline silicon solar cell technology. The processing procedure also includes how to make solar modules taking advantage of the back-side contact characteristic of the cells. Based on the better cost/Wp ratio a natural exploitation of the results is expected by replacing existing technology in future solar cell production lines.
