На эти как раз и прицел.

В Январе этого (2011) года запросил информацию у дочерней компании Боинга
о ячейках C1MJ.
Вот их ответ:
=======================
dear sir
-
Assuming 50 W/cm2 flux and efficiency of 37.5% under 25° C, our 36% cell produces 18.8 W. Since actual operating temperature will be higher, counting on 18 W per cell is a reasonable assumption.
Our most common cell size is the 36% efficiency cell. This is a concentrator cell with dual busbars (the two metal bars on the edge of the solar cell), and an area of 1 cm2. This cell can be purchased in three configurations:
1) Bare cell USD 15 DOLLAR BIG ORDER PER PIECE
minimum 100000 pieces order
A: We have achieved 40.7% conversion efficiency in December 2006. This result was verified independently . This record efficiency was achieved at 240x concentration and 25° C
non-uniform flux, the efficiency will drop and temperature variation could cause reliability issues.
The question of how to cool the cells is up to the CPV system designer.. Typically dense-array modules are actively cooled; whereas point focus systems may be actively or passively cooled.
During assembly, the cells can be exposed to temperatures as high as 300° C for a few minutes. During operation, we suggest maintaining a temperature below 100°C. Higher operating temperatures will reduce the cell efficiency and may jeopardize the lifetime of the cells in the field. Cell performance is a function of temperature. For every 10° C rise in cell temperature, the cell efficiency drops by about 0.5% absolute efficiency. That is, a 38% cell at 25° C will be a 37% cell at 45° C.

Умножаем 15 у.е. на 100'000 и получаем 1,5 млн. у.е. - минимальная партия заказа.
Вот это серьезный подход к делу, ("бизнесу")!
На мой запрос о двух других вариантах поставки ячеек и о цене для NNNN-ого дистрибьютора и пробных семплах - ни ответа, ни привета.
Вот реквизиты, в надежде - может кому-то повезет больше:
