I thought this might be important for you to read as an alternative non-consipircy theory reason why the cell isn't being manufacutured - Below are some exceprts from the annual report of one of the most successfull worldwide solar manufacturers... emphasis on declining prices and excess capacity with declining average selling prices over time. Long story short panel pricing is low enough that the profit is in the installation and excellent customer service makes the difference.
"The solar industry continues to be characterized by intense pricing competition, both at the module and system levels. In the aggregate, we believe manufacturers of solar modules and cells have, relative to global demand, significant installed production capacity and the ability for additional capacity expansion. We believe the solar industry may from time to time experience periods of structural imbalance between supply and demand (i.e., where production capacity exceeds global demand), and that such periods will put pressure on pricing."
"Worldwide solar markets continue to develop, in part aided by demand elasticity resulting from declining industry average selling prices, both at the module and system level, which make solar power more affordable to new markets."
"Lower industry module and system pricing, while currently challenging for certain solar manufacturers (particularly manufacturers with high cost structures), is expected to continue to contribute to global market diversification and volume elasticity. Over time, declining average selling prices are consistent with the erosion of one of the primary historical constraints to widespread solar market penetration, its affordability."
