a method for manufacturing optoelectronic devices comprising the steps of : providing a common growth substrate ; forming a light - emitting epitaxy structure on the common growth substrate ; forming a stripping layer on the light - emitting epitaxy structure ; forming a solar cell epitaxy structure on the stripping layer ; forming an adhesive layer on the solar cell epitaxy structure ; proving a solar cell permanent substrate on the adhesive layer ; and removing the stripping layer to form a light - emitting device and a solar cell device separately .
