The impact damage effect of solar cell is of concern in engineering so experiments of hypervelocity impact of small particles on solar cell cover glass is carried out on Space Particulate Impact Facility. Through experiments crater morphology on different particle diameter and velocity was deprived and the statistical law of crater diameter was constituted furthermore we had tested the optical penetration rate on crater area and got the primary results.
