Abstract
【解決手段】 キセノンランプ1からパルス波形の頂部が平坦になるフラッシュ光を発光させる。このフラッシュ光を照度検出器3で受光してその照度を検出し、該検出値に基づいて光源の照度を狭い規定範囲内に制御する。そして規定範囲内の照度のフラッシュ光を被測定体としての太陽電池4に照射し、該太陽電池4の負荷を制御しながら太陽電池4から出力される電流と電圧を複数点測定する。これを、複数回のフラッシュ光について行い、太陽電池4のI−Vカーブを得る。
【選択図】 図1
Description
(1) 1フラッシュ光の間に負荷をステップ状に掃引することで、少ないフラッシュ点灯数で測定可能となり、測定時間を短縮することができる。例えば、フラッシュ点灯サイクルを約1secとして5回のフラッシュ光で測定した場合、測定時間は約5secで高速測定を実現できる。因みに、従来のショートパルス式の場合、100〜160回フラッシュ点灯すると、測定時間は、約15〜30secである。
