Merits of Thin-Film Si Photovoltaic Modules Merits Remarkably low consumption of raw Si material ( < 1% of consumption of bulk crystalline silicon modules)

Good and reliable outdoor performance

Thin-film Si solar cells

Crystalline Si solar cells

thickness: 0.3 - 3 μm

thickness: 150-300 μm

Temperature coefficient: - 0.2%/°C

Temperature coefficient: - 0.5%/°C

Normalized efficiency: 100% @ 25°C 91 % @ 70°C

Normalized efficiency: 100% @ 25°C 78 % @ 70°C

Low-temperature deposition (low cost substrates such as glass and flexible plastics are available)

Process temperature: 200°C (thin-film deposition process)

Process temperature: 400°C~1000°C (diffusion process)

Create synergy with the infrastructure of the LCD industry

Similar to the LCD technology

Similar to the semiconductor technology

Considerable margin for the improvement of the conversion efficiency via tandem cell structures

Stabilized efficiency: 6.5% (single) 10% (double junction) 14% (triple junction)

Efficiency: 14% (multicrystalline) 18% (single crystalline)


Annual Power Generation Using Photovoltaic Modules

*Refer to) http://www.mhi.co.jp

*Refer to) http://www.pv.kaneka.co.jp

Annual power generation using thin-film silicon modules is 10-15% higher than that of using bulk crystalline silicon modules
