Recent Results of Europe-Japan Collaborative Research on Concentrator Photovoltaics

The Europe-Japan Collaborative Research Project on Concentrator Photovoltaics (CPV) has been initiated under support by the EC (European Commission) and NEDO (New Energy and Industrial Technology Development Organization) since June 2011. This paper presents outline and recent results of this project. Under this project, world-record efficiency (43.5% under 240-305 –suns) InGaP/GaAs/InGaAs 3-junction cell has been demonstrated by Sharp Co. Such efficiency has been confirmed by FhG-ISE.
