しかも、従来の分光感度測定装置によって出射可能な単色光の照射強度は０．５〜５ｍＷ／ｃｍ２程度であるため、５ｍＷ／ｃｍ２を超える照射強度を必要とする太陽電池の分光感度測定には適用することができないといった問題があった。特に、低コストの太陽電池として近年注目されている色素増感型太陽電池は、５ｍＷ／ｃｍ２を越える照射強度が必要とされ、従来の分光感度測定装置での測定には限界があった。 Moreover, the irradiation intensity of the conventional spectral sensitivity measuring apparatus capable monochromatic light emitted by the order of the order 0.5~5mW / cm 2, the spectral sensitivity measurement of the solar cell that requires irradiation intensity exceeding 5 mW / cm 2 There was a problem that could not be applied.

入射光学系１０２の長波長光源１０２Ａ（又は短波長光源１０２Ｄ）から出射した光は、分光光学系１０４の入射スリット１０４Ａを介して凹面グレーティング１０４Ｂに入射する。そして、凹面グレ−ティング１０４Ｂに入射した光は、凹面グレ−ティング１０４Ｂで所定スペクトルの単色光に分光された後、出射スリット１０４Ｃを介して出射光学系１０６に出射する。出射光学系１０６に入射した単色光は、出射光学系１０６において高次光の除去、光量の調整等がなされた後、被測定物１１０に照射される。なお、単色光の波長帯域４００ｎｍ〜１２００ｎｍにおける照射強度は、０．５ｍＷ／ｃｍ２以上とされており、特に、単色光の波長帯域４００ｎｍ〜８００ｎｍにおける照射強度は、５ｍＷ／ｃｍ２〜１０ｍＷ／ｃｍ２とされている。 The light emitted from the long wavelength light source 102A (or short wavelength light source 102D) of the incident optical system 102 enters the concave grating 104B via the incident slit 104A of the spectroscopic optical system 104.

一方、バイアス光学系１０８のバイアス光源１０８Ａから出射する光は、出射光学系１０６から照射される単色光に重畳された状態で、被測定物１１０に照射される。   On the other hand, the light emitted from the bias light source 108 </ b> A of the bias optical system 108 is irradiated onto the object 110 to be measured while being superimposed on the monochromatic light emitted from the emission optical system 106.

本実施形態の一例に係る分光感度測定装置１００によれば、分光光学系１０４は、凹面グレーティング１０４Ｂを有して構成されているため、従来よりも単色光の照射強度を増大することができる上に、凹面鏡などの結像素子を用いずに分光光学系を構成することができ、簡易構造、且つ、低コストの装置にすることができる。   According to the spectral sensitivity measuring apparatus 100 according to an example of the present embodiment, the spectroscopic optical system 104 is configured to include the concave grating 104B, so that the irradiation intensity of monochromatic light can be increased as compared with the conventional case.

The single concave grating 104B can cover all the wavelength band (400 nm to 1200 nm) necessary for measuring the spectral sensitivity of the solar cell, and can provide a predetermined irradiation intensity (0.5 mW / cm 2 or more) in that wavelength band. Can be secured.

特に、単色光の波長帯域４００ｎｍ〜８００ｎｍにおける照射強度が、５ｍＷ／ｃｍ２〜１０ｍＷ／ｃｍ２とされているため、単色光を太陽光スペクトルの特性に、より近づけることができ、精度の高い分光感度測定が可能な上に、５ｍＷ／ｃｍ２を超える照射強度を必要とする太陽電池（例えば、色素増感型太陽電池など）の分光感度測定にも適用が可能である。 In particular, the irradiation intensity in the wavelength band 400nm~800nm of monochromatic light, since there is a 5mW / cm 2 ~10mW / cm 2 , the monochromatic light on the characteristics of the solar spectrum, it is possible to more approximate, accurate spectral In addition to being able to measure sensitivity, the present invention can also be applied to spectral sensitivity measurement of solar cells (for example, dye-sensitized solar cells) that require irradiation intensity exceeding 5 mW / cm 2 .

従って、例えば、入射光学系１０２は長波長光源１０２Ａ及び短波長光源１０２Ｄの２つの光源を備えているが、本発明はこれに限定されるものではなく、入射光学系を１つの光源で構成してもよい。又、単色光の照射強度も、上記実施形態において示した数値に限定されるものではない。   Therefore, for example, the incident optical system 102 includes two light sources, a long wavelength light source 102A and a short wavelength light source 102D. However, the present invention is not limited to this, and the incident optical system is configured by one light source. May be. Further, the irradiation intensity of monochromatic light is not limited to the numerical values shown in the above embodiment.
