The photoluminescence (PL) excitation spectrum of Eu chelate shows that the violet light below 400 nm is effectively converted to the red emission at 613 nm. Since the PV cell has higher sensitivity at the red wavelength region compared to the violet region, Eu chelate is one of the suitable material for a WCF. The diameter of fabricated sol–gel encapsulated Eu chelate was larger than the wavelength of irradiated sunlight, therefore, the transmittance of a WCF decreased with increasing the concentration of Eu chelate. The short circuit current (JSC) was increased by inserting the the WCF on the front side of Si-PV cell compared to the reference module (glass/ethylene vinyl acetate/WCF without Eu chelate/Si-PV cell/EVA/back-film), and the maximum increase of ΔJSC was 1.03 mA/cm2 compared to the reference module. However, the maximum ΔJSC of fabricated module was almost same as the conventional Si-PV cell due to the refractive index mismatch of each layers., text, application/pdf}, pages = {22--25}, title = {Wavelength conversion film with glass coated Eu chelate for enhanced silicon-photovoltaic cell performance}, volume = {32}, year = {2009}, yomi = {フクダ, タケシ and ホンダ, ゼンタロウ and カマタ, ノリヒコ} }
