Ooh, conspiracy theories!

Furthermore, solar panels with a 20% or greater efficiency can't be made because of the Secrecy Act. So much for alternative energy. I guess we'll be using oil until it's going to lose the government more money than a solar panel that's 20% efficient. :P Guess all of the researchers should give up and go home then: solar cell efficiencies.
The problem is that to get to the higher efficiencies generally requires the multijunction cells of non-silicon semiconductors which is expensive. A perfect P-N junction silicon solar cell taking only the bandgap into account is fundamentally limited to ~33% efficiency by the mismatch between the bandgap and the incoming photon energy spectrum. So we're doing pretty well at ~17% for commonly available panels.
