Description
上式において、Rは、レンズの曲率半径(球状タンクに対して〜約19,8cm(7.8インチ))である。μ1、μ2及びRに対して上記値を代入すると、約80cm(約31.5インチ)の焦点距離が計算される。この焦点距離及びタンクに当たる平行光線のための光線追跡に基づくと、水性電解質で充填された約40cm(15.7インチ)直径のタンクの中央部に取り付けられた、約27.9cm(約11インチ)の直径を備えるPVモジュール5は、約2の因子の光電性能増加度を享受することになる。PVモジュールがタンク1の背部の近傍に置かれ、電極3及び4が、PVモジュール5に向かって進む太陽光線の進路から外れて取り付けられた場合、約20.3cm(8インチ)PVモジュールに対して計算された約3.8の光電性能増加度が予想される。
