Applications　of　photovoltaic　(PV)　cells　in　buildings　are　often　excluded　from　locations　with　major　mechanical　strains　because　of　their　brittleness　and　possible　damages　at　small　mechanical　strains.　Combinations　of　glass　fibre　reinforced　polymer　(GFRP)　components　and　amorphous　silicon　(a-Si)　photovoltaic　cells　show　potentials,　while　the　effects　from　elevated　temperatures　and　mechanical　loads　on　the　electrical　performance　of　the　integrated　PV　cells　need　to　be　well　understood.　In　this　study,　specimens　were　fabricated　by　adhesively　bonding　a-Si　PV　cells　to　GFRP　sandwich　structures.　The　specimens　were　then　exposed　to　outdoor　natural　sunlight.　The　sunlight　intensities　and　the　temperature　responses　at　different　locations　of　the　specimens　were　continuously　monitored　and　their　correlation　was　quantified.　An　approach　was　proposed　to　calculate　the　sunlight　intensities　received　by　the　integrated　PV　cells　and　their　temperature　responses　based　on　geographic　information　(e.g.　longitude,　latitude　and　altitude)　of　such　applications.　The　electrical　performance　of　the　integrated　PV　cells　was　then　investigated　under　four-point　bending　until　structural　failure.　Two　loading　scenarios　were　considered　where　non-uniformly　distributed　tensile　or　compressive　strains　were　introduced　into　the　integrated　PV　cells.　Reductions　in　voltage　of　the　integrated　PV　cells　were　highlighted　due　to　non-uniform　distribution　of　strains.
