Was not InP also targeted for InP (radiation-hardened) applications? I thought I read about this a few years ago on this forum.

I did some research and came up with this: http://onlinelibrary.wiley.com/doi/10.1002/1099-159X(200005/06)8:3%3C349::AID-PIP326%3E3.0.CO;2-Z/abstract

Abstract

The effect of proton irradiation on the photovoltaic response of p-i-n InP solar cells that include an InP/InAsP multi-quantum well (MQW) layer in the intrinsic region is studied. Data from cells with three different quantum well structures are presented along with data from a control cell grown without MQW layer. The results show how the addition of the MQW's improves the solar energy conversion efficiency thereby allowing the base to be as thin a 1 μsm while still maintaining a good photocurrent. In addition, the radiation response of the MQW cells is shown to be equal to or better than the InP control cell. Published in 2000 by John Wiley & Sons, Ltd.
