Stress mitigation for adhesively bonded photovoltaics with fibre reinforced polymer composites in load carrying applications

Thomas Keller, Yu Bai

Structural loads, especially in-plane compression, may cause local buckling and debonding of the photovoltaic (PV) cells that are mechanically integrated with structural members and this may lead to degradation in their electrical performance. This paper p ...
