SUMMARY

The discussion focuses on finding a suitable cover material for B50 solar cells, which have an efficiency of 21%. The key requirements for the cover material include being watertight, made from thermoplastic for effective sealing, having low mass, and absorbing minimal photons of 1.1 eV and higher. Participants suggest alternatives to glass, specifically considering plastics like acrylic and polycarbonate as potential solutions.

PREREQUISITES
  • Understanding of solar cell technology, specifically B50 cells
  • Knowledge of material properties, particularly thermoplastics
  • Familiarity with photon absorption characteristics
  • Basic principles of waterproofing materials
NEXT STEPS
  • Research the properties of acrylic and polycarbonate for solar applications
  • Explore thermoplastic sealing techniques for solar cell covers
  • Investigate alternative materials that meet the specified photon absorption criteria
  • Study the impact of cover material weight on solar cell performance
USEFUL FOR

Engineers, materials scientists, and solar energy developers seeking to optimize the performance and durability of solar cell installations.

In my project i have solar cells we use are called B50 cells with an efficiency of 21%.

Since the cells come in contact with water we are looking for a cover material that is first of all watertight and secondly it should influence the performance as less as possible. Last but not least the weight of the cover material should be very low.

Requirements:
• Watertight
• The material should be a thermoplastic in order to seal it
• Low mass
• Absorb minimal fotons of 1,1 eV and higher.

Expected results:

A list of materials with its specifications.

so can please anybody help

I'm guessing you don't want glass. How about a plastic like acrylic or polycarbonates?
