「革新的太陽光発電技術研究開発」事業では、平成23 年度より、新たな研究開発項目「高効率集光型太陽電池セル、モジュール及びシステムの開発(日EU 共同開発)」を追加し、日EU の知見・技術を結集することで、集光型太陽光発電技術のブレークスルーと技術開発の更なる加速、さらに日本に適した集光型太陽光発電システム技術の確立も目指している。
英文要約Title:Ultra-high efficiency concentration photovoltaic’s (CPV) cells, modules and Systems WP4:Development of characterization tools for CPV cells, modules and systems (FY2011-FY2012) FY2011 Annual Report
1. Characterization technologies for concentration photovoltaic (CPV) cell
For the purpose of an indoor round-robin measurement with EU research institute (Fraunhofer Institute for Solar Energy Systems ISE), we have confirmed the basic performance of a high intensity pulsed solar simulator, and improved the accuracy by adjusting the spatial uniformity of the irradiance (< ±2.0 % over 5 cm x 5 cm area), the spectral irradiance (the same photocurrent generated in each component cell as that under the reference solar spectrum < ±2.0 % accuracy, while satisfying the spectral match of < 10 % with the reference solar spectrum), the temporal stability of the irradiance during a light of pulse and the repeatability of the irradiance of < 1.0%, and selected the probe reducing the contact resistance. We have also confirmed the feasibility of the I-V performance characterization of CPV cells under concentration of up to 700 suns, and carried out the 1st indoor round-robin measurement with Fraunhofer ISE. 2. Characterization technologies for concentration photovoltaic (CPV) mini-modules For the purpose of an indoor round-robin measurement with EU research institute (Fraunhofer Institute for Solar Energy Systems ISE), we have confirmed the basic performance of a highly parallel continuous solar simulator, and improved the accuracy by adjusting the spatial uniformity of the irradiance (< ±2.0 % over 18 cm x 18 cm area), the spectral irradiance (the same photocurrent generated in each component cell as that under the reference solar spectrum < ±2.0 % accuracy, while satisfying the spectral irradiance requirement for class A(ASTM E927-10)). We have analyzed the angular distribution of the irradiance averaged over an effective illuminated area of 18 cm x 18 cm, and the angular dependency of the CPV mini-module performance. We have upgraded the tracker to evaluate the CPV mini-module performance outdoors.
