Outline of Final Research Achievements

A prototype photovoltaic (PV1) module using 1500 spherical solar micro-cells having 1.8 mm diameter with 15.4 cells cm-2 density in 97 mm2 area was developed for greenhouse roof applications. The electrical and shading characteristics of the PV1 module were measured and evaluated. Subsequently, a larger (910 mm x 610 mm) semi-transparent PV module (PV2) was developed matching the size of greenhouse roof frames. PV2 was produced using 4800 spherical solar micro-cells with 1.2 mm diameter. The sunlight eclipsing percentage of the cells was 9.7%. The electrical and shading characteristics of the PV2 module were measured and evaluated. The performances and possible applications of the PV1 and PV2 modules were reported at scientific meetings and journals.
