Abstract :
The prototype solar sheet using the paper-like thin film InGaP/GaAs solar cells and thin bypass diodes we newly developed was fabricated. The output power of the prototype solar sheet is 11.3W (Voc=11.88V, Isc=1.12A, F.F.=0.854), and the weight is about 16.7g. So output power per weight is about 0.68W/g. The preliminary reliability tests (thermal shock test, humidity test, high temperature vacuum test) are carried out in the solar sheet. Good reliability of the solar sheet has been confirmed in these tests.
