Hi everyone, I want cleared something. We are searching solar cells or non qualified solar cells for a cubesat to make electrical test. It is not important if they are form Emcore, Spectrolab or whatever. We need between 6 and 12 cells.
Nick, how much cells do you need?
Thanks you very much Ignacio
PD: Apologies for change the topic, sorry.

Bob,
The Voc (open circuit) = 2.7V aprox The Isc (short circuit) = 455 mA aprox
The value are aproximate because depends on the technology ATJ, BTJ, ZTJ, MATJ, MBTJ, MZTJ
This link show the cells and their datasheets http://www.emcore.com/solar_photovoltaics/space_solar_cells
Important, these value are infomation about standars cells, not for the cells with mechanical or electrical anomalies
The area is 26.6 cm2 and the size is like a rectangle of 4 x 8 cm (aprox). Enter two cells on each side of the cube.
Thanks Ignacio

Ignacio,
What is the SIZE of the cell and the output current.? I assume the voltage is 2.4v each?

From: Ignacio de León roverano8@gmail.com This is the email that Emcore answered to me.
EMCORE does offer mechanical/visual (MV) bare solar cells (MV cells are not available in SCA's). MV solar cells have mechanical anomalies or discoloration that make them unusable for space. MV solar cells have an efficiency typically greater than 25% at AM0 and 28°C.
Price
EMCORE offers MV cells for $50.00 (USD) each with a minimum order quantity of 150 cells.
Terms and Conditions
EMCORE’s MV cells are offered on an “as available, first come, first serve” basis. EMCORE’s standard terms and conditions for MV cells are as follows:
- Parts sold on an “as is” basis with no
warranty. All sales are final. 2. Quantities offered are subject to continued inventory availability. 3. Payment is required in advance of shipment by bank transfer or credit card. 4. Customer is responsible for all shipping costs (including insurance) from freight forwarding office. 5. Minimum purchase price is $7,500.00 for any order.
Sorry for bother Warm regards from Uruguay Thank you very much.
