Description
例えば宇宙飛行用電力の用途に用いられる、ソーラーセルアレイの設計に関する新たな手法は、アレイ内のソーラーセル間の電気的接続に基づいている。
ソーラーセル14間には、複雑な電気的接続が必要とされる。この新しい手法は、基板12上でプリント、エッチング、又は形成された、パターン化されたコーナー導体20を使用する。代替的な実施例では、基板12は、剛性であるPCB、又は可撓性である可撓性シート組立品であり得る。
これらのコーナー領域26におけるソーラーセル14間の電気的接続の使用は、製造を容易にするが、カストマイズを制限する場合がある。例えば、ソーラーセル14は、高電圧出力を生成するため、直列に接続されており、これはストリングとして知られている。このストリングを構築するのに必要なソーラーセル14の数は、幾つかの理由により変動し得る。ストリングの終端は、電気的接続の一部となる。したがって、電気的接続は、あらゆる回路の長さについてカスタマイズする必要がある。これは、費用がかかり、遅延が生じる。したがって、望ましくない。
コーナー領域26におけるソーラーセル14間の電気的接続を使用することにより、自動化が促進されるが、この設計の電力生成能力、製造可能性、及び残存可能性には限界がある。特に、既存の解決策を用いてアレイ22から電力を取り出すことには、アレイ22の表面にわたってワイヤ82を通すことが必要とされるが、これには困難とリスクが伴う。
本セクションは、ソーラーセル14間に電気的接続をもたらすために、ソーラーセル14及び/又はダイオード44が基板12に取り付けられる前及び/又は後に、コーナー領域26内の基板12上に金属コーナー導体20をプリントすることを説明する。コーナー導体20をプリントすることは、製造を簡略化することができ、それと同時にカスタマイズをもたらす。電気的接続は、プリントされたコーナー導体20を用いて任意の所望の方法で行うことができ、設計を修正する労力が少ない。
本開示の各実施例は、図45に示すステップ116~128を含む、ソーラーセル14、ソーラーセルパネル10a、及び/又は人工衛星の製作方法114に関連して記載されていてよく、結果として製作される、ソーラーセル14からなるソーラーセルパネル10aを有する人工衛星130は、図46に示される。
