Description
基材中に紫外線吸収剤を含む樹脂製太陽光集光用光学シートの設計方法であって、
メタルハライドランプ式耐候性試験(装置規格:JTM G 01:2000、日本試験機工業会)による加速劣化試験において、
T1時間の照射時間で試験した後の、400nm〜1850nmの波長領域における平均透過率の低下が
τuv(0)+τuv(T1)>τ0(0)+τ0(T1) (1)
を満たし、かつ、上記波長領域で各波長毎に初期値からの透過率低下が10%以下であるように基材中に含有させる紫外線吸収剤の量を決定することを特徴とする太陽光集光用光学シートの設計方法により解決できる。
ただし、
T1=150×2.5×U1/U0
×{0.44×ln(W1/W0)+0.88}

基材中に紫外線吸収剤を含む樹脂製太陽光集光用光学シートの設計方法であって、
メタルハライドランプ式耐候性試験(装置規格:JTM G 01:2000、日本試験機工業会)による加速劣化試験において、
T1時間の照射時間で試験した後の、400nm〜1850nmの波長領域における平均透過率の低下が
τuv(0)+τuv(T1)>τ0(0)+τ0(T1) (1)
を満たし、かつ、上記波長領域で各波長毎に初期値からの透過率低下が10%以下であるように基材中に含有させる紫外線吸収剤の量を決定することを特徴とする太陽光集光用光学シートの設計方法により解決できる。
ただし、
T1=150×2.5×D1/D0 (3)
D1:太陽光集光用光学シートを使用する環境での平均直達日射量

右辺は前記基材の種類が定まれば設置場所の条件により定まる。左辺のうち、τuv(0)は紫外線吸収剤の含有量が多いほど小さくなるが、τuv(T1)については紫外線吸収剤の含有量が多いほど大きく(透過率の低下が少なく)なる傾向にあり、そのため適正な紫外線吸収剤の添加量を与える式となっている。
