## Abstract

Disclosed is a solar cell apparatus. The solar cell apparatus includes: a solar cell panel including a central region and an outer region surrounding the central region; a first adhesive member adhered to the central region; a second adhesive member adhered to the outer region and having an adhesive strength greater than the first adhesive member.

## Claims

### Claim 1

A solar cell apparatus comprising:
a solar cell panel;
a buffer member making direct contact with the top surface of the solar cell panel;
an adhesive member disposed on the solar cell panel and adhered to a surrounding region of the buffer member in a top surface of the solar cell panel; and
a protective panel disposed on the buffer member and the adhesive member, wherein the adhesive member has an area greater than the buffer member.

### Claim 2 (depends on 1)

The solar cell apparatus of claim 1, wherein the adhesive member has a closed- loop.

### Claim 3 (depends on 1)

The solar cell apparatus of claim 1, wherein the adhesive member surrounds the buffer member.

### Claim 4 (depends on 1)

The solar cell apparatus of claim 1, wherein the adhesive member covers side and top surfaces of the buffer member.

### Claim 5 (depends on 1)

The solar cell apparatus of claim 1, wherein the adhesive member comprises ethylene vinyl acetate which has about 40 wt % to 60 wt % of vinyl acetate.

### Claim 6 (depends on 1)

The solar cell apparatus of claim 1, wherein the buffer member has an adhesive strength less than the adhesive member.

### Claim 7 (depends on 1)

The solar cell apparatus of claim 1, wherein the buffer member is attachable/detachable to/from the solar cell panel.
