可選透明度 Customized degree of transparency*: 20%-40%

*透明度會影響發電效率，因而影響安装面積和成本回收週期
Degree pf transparency would influence generation efficiency and in turn, installation area and length of pay-back period.

早於 2015年，團隊已把單結有機太陽能電池 效能提升至世界最高的 11.5%，並獲美國能源部國家再生能源實驗室 (NREL) 正式確認為主要科技突破，並刊登於 國際知名的「最佳效能研究電池圖表」上。

Earlier in 2015, the team achieved single-junction organic solar cells with a record efficiency of 11.5%, which has been officially certified. This achievement is noted as a major technological breakthrough in the renowned National Renewable Energy Laboratory (NREL) (US Dept of Energy) chart of “best research-cell efficiencies”.
