In summary, the project involves using solar cells with 21% efficiency called B50 cells, which need a watertight cover material that has minimal impact on performance and low weight. The desired material should be a thermoplastic, have low mass, and absorb minimal photons of 1.1 eV or higher. The expected results are a list of suitable materials with their specifications, and suggestions like acrylic or polycarbonates have been proposed as alternatives to glass.

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?
 

1. How does a material achieve watertight properties?

A material can achieve watertight properties through its molecular structure. A material with a tightly packed molecular structure, such as metals, can prevent water from seeping through. Additionally, materials with a hydrophobic surface can repel water and maintain a watertight seal.

2. What are some examples of watertight materials?

Examples of watertight materials include metals, such as aluminum or stainless steel, rubber, plastic, and certain types of coatings, such as epoxy or polyurethane. Some textiles, like Gore-Tex, are also designed to be watertight.

3. Can a material be both watertight and lightweight?

Yes, some materials are designed to be both watertight and lightweight. For example, aluminum can be coated with a waterproof layer to make it watertight while still maintaining its lightweight properties. Additionally, certain types of plastics and composites can also be lightweight and watertight.

4. How can a material be made watertight without adding weight?

One way to make a material watertight without adding weight is by using a coating or sealant on the surface. This creates a barrier between the material and water, without significantly increasing its weight. Another method is to use a material with a naturally tight molecular structure, such as certain types of plastics.

5. What are the benefits of using watertight and low weight materials?

Using watertight and low weight materials can have several benefits. It can help prevent water damage and corrosion, which can increase the lifespan of a product. Additionally, these materials can be more cost-effective and energy-efficient, as they require less maintenance and can be transported more easily due to their lightweight nature.
