Hi Jeff,

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: 1. 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.

The standars cells cost $650 (USD) aprox per cell 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.

We can not pay more than $70 (USD) per cell

Warm regards from Uruguay Thank you very much.

AMSAT and CUBESAT:

A student CUBESAT group in Uruguay wants to partner with another CUBESAT group to purchase the minimum quantity (150) of triple jnction solar cells from EMCOR. They only need a dozen.

Anyone want to team up?
